    Study Notes

    Heart Failure

    • Heart failure (HF) occurs when the heart cannot pump enough blood to meet the body's needs.
    • HF results from damage or stress on the heart muscle, impacting both contractility (pumping) and relaxation.
    • Reduced heart function leads to decreased cardiac output (CO), impacting tissue perfusion.
    • The body compensates for reduced CO by activating mechanisms that lead to vascular congestion, hence the term "congestive heart failure."
    • HF is a progressive condition, worsening over time as the heart muscle weakens.
    • Common causes include coronary heart disease, myocardial infarction (MI), cardiomyopathy, myocarditis, hypertension, and structural heart disorders.
    • Acute conditions like volume overload, hyperthyroidism, and pulmonary embolism can also trigger HF symptoms.

    Impaired Myocardial Function

    • Coronary Heart Disease: A leading cause of heart failure, caused by blockages in the coronary arteries. Reduced blood flow to the heart muscle can weaken it.
    • Cardiomyopathies: Diseases that affect the heart muscle, such as dilated cardiomyopathy (enlarged heart chamber) and hypertrophic cardiomyopathy (thickened heart muscle).
    • Rheumatic Fever: An inflammatory condition that can damage heart valves. This can happen after a strep throat infection.
    • Infective Endocarditis: A bacterial infection of the heart valves, causing inflammation and damage.

    Increased Cardiac Workload

    • Hypertension: High blood pressure forces the heart to work harder, leading to damage over time.
    • Valve Disorders: Aortic stenosis (narrowed aortic valve) and mitral regurgitation (leaky mitral valve) increase the workload on the heart.
    • Anemias: Conditions where the blood carries less oxygen, making the heart work harder to supply oxygen to tissues.
    • Congenital Heart Defects: Heart defects present from birth can increase workload and eventually lead to heart failure.

    Acute Noncardiac Conditions

    • Volume Overload: Sudden increase in body fluid, putting extra strain on the heart.
    • Hyperthyroidism: Overactive thyroid gland, causing the heart to beat faster and harder.
    • Fever and Infection: Fever and infection can increase metabolic demands and strain the heart.
    • Massive Pulmonary Embolus: Blood clot in the lungs creating a blockage, requiring the heart to work harder to pump blood.

    Pulmonary Edema

    • Pulmonary edema is a serious condition resulting from the buildup of fluid in the lungs.
    • Fluid accumulates in the interstitial tissues and alveoli of the lungs.
    • It is a frequent consequence of heart failure (HF).
    • Cardiogenic pulmonary edema specifically is a sign of severe heart failure.
    • This type of pulmonary edema occurs when the heart can no longer effectively pump blood to the body.
    • This leads to backup in the lungs.
    • It is a medical emergency:
      • Requires immediate treatment
      • Onset can be gradual or abrupt
      • Worsens to severe respiratory distress

    Cardiac Output

    • Cardiac output (CO) is the amount of blood ejected from the ventricles in 1 minute.
    • CO is impacted by functioning muscle mass and ventricular coordination
    • Increasing tissue oxygen demand increases CO to meet the need.
    • The ability of the heart to increase CO is called cardiac reserve.
    • Ventricular damage reduces cardiac reserve.
    • Stroke volume and heart rate produce CO.
    • Heart rate is the number of ventricular contractions per minute.
    • Stroke volume is the amount of blood expelled with each contraction.

    Heart Rate

    • The autonomic nervous system, catecholamines, and thyroid hormones influence heart rate.
    • Stress, fear, or hypovolemia stimulate the sympathetic nervous system (SNS).
    • SNS stimulation increases heart rate and stroke volume.
    • Rapid tachycardia shortens diastole (ventricular filling time) which can reduce stroke volume (SV) and CO.
    • Significant bradycardia can also reduce CO.

    Stroke Volume

    • Stroke volume is determined by preload, afterload, and myocardial contractility.

    Ejection Fraction

    • Ejection fraction is a measurement of the heart’s effectiveness.
    • A normal ejection fraction is 50–70%.
    • When the heart begins to fail, CO, SV, and ejection fraction decrease.

    Compensatory Mechanisms for Heart Failure

    • The Frank–Starling mechanism, neuroendocrine responses (SNS and RAAS activation), and myocardial hypertrophy are compensatory mechanisms for impaired heart function.

    Compensatory Mechanisms in Heart Failure

    • Frank-Starling Mechanism: The heart’s ability to increase contractile force when stretched, which is essential for maintaining cardiac output (CO) in heart failure. However, this mechanism has limitations; excessive stretching can lead to decreased contractility.

    • Neuroendocrine Response:

      • Sympathetic Nervous System (SNS) Activation: This response increases heart rate, blood pressure (BP), and contractility, initially trying to compensate for the decreased CO. However, prolonged SNS activation can lead to tachycardia, decreased filling time, and ultimately reduced CO.
      • Renin-Angiotensin-Aldosterone System (RAAS) Activation: This system is crucial for regulating blood volume and pressure. Activation increases aldosterone release, leading to sodium and water retention, further contributing to increased preload and afterload. However, this can also lead to pulmonary congestion, fluid retention, and ultimately reduced renal perfusion.
      • Antidiuretic Hormone (ADH) Release: Increases water reabsorption, contributing to fluid retention and worsening congestion.
      • Atrial Natriuretic Peptide (ANP) and Brain Natriuretic Peptide (BNP) Release: These hormones promote diuresis and vasodilation, counteracting the effects of RAAS activation.

    • Ventricular Hypertrophy:

      • The heart muscle adapts to chronic overload by thickening, increasing its contractile force. However, this comes at a cost: increased myocardial oxygen demand and a risk of cellular enlargement, potentially leading to further complications.

    • Potential Complications:

      • Increased myocardial work and oxygen demand
      • Decreased perfusion of other organ systems
      • Pulmonary congestion
      • Increased preload and afterload
      • Renal failure
      • Anaerobic metabolism and lactic acidosis

    Cardiovascular System and Cardiac Output (CO)

    • Baroreceptors in the aorta sense reduced CO and trigger the sympathetic nervous system (SNS) to release norepinephrine.
    • Norepinephrine increases heart rate and contractility by stimulating beta-receptors in the heart.
    • It also causes vasoconstriction in arteries and veins, increasing venous return to the heart.
    • Increased venous return improves ventricular filling and stretches the myocardium, leading to a stronger contraction according to the Frank-Starling mechanism.
    • Excessive myocardial stretch can lead to ineffective contractions.

    Blood Flow Prioritization

    • The cardiovascular system prioritizes blood flow to the brain and heart during reduced blood flow.
    • Reduced blood flow to the kidneys triggers the renin-angiotensin-aldosterone system (RAAS).

    RAAS Activation and Fluid Retention

    • RAAS activation causes vasoconstriction and stimulates the adrenal cortex to release aldosterone, increasing sodium reabsorption and water retention.
    • The posterior pituitary gland releases ADH, further inhibiting water excretion and causing vasoconstriction.
    • Overall, RAAS activation increases vascular volume, improving CO.

    Counteracting RAAS and ADH

    • Atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP) are released from atrial and ventricular tissues, respectively.
    • ANP and BNP promote sodium and water excretion while inhibiting norepinephrine, renin, and ADH secretion.
    • However, their vasodilatory action is weak and does not fully counteract the fluid retention and vasoconstriction associated with heart failure (HF).

    Structural Changes in Heart Failure

    • Structural changes in the heart, such as ventricular hypertrophy, occur in response to increased fluid volume and ventricular pressures.
    • Ventricular hypertrophy increases myocardial actin and myosin components for enhanced contractility.
    • Although beneficial initially, these changes hasten cardiac dysfunction over time.

    Heart Failure Etiology and Progression

    • Heart failure develops due to the decompensation of multiple cardiac mechanisms.
    • Increased heart rate reduces diastolic filling time and coronary artery perfusion, leading to ischemia.
    • Prolonged SNS stimulation reduces beta-receptor response, inhibiting rate variability and depleting myocardial norepinephrine stores.
    • Peripheral vascular alpha-receptors become more sensitive to stimulation, increasing afterload.
    • Chronic myocardial wall distention results in cellular degeneration and ventricular dilation, leading to inadequate coronary blood supply and ischemia.
    • Stretch fibers become compromised, leading to ineffective contractions.
    • Chronic distention depletes ANP and BNP stores, leading to unopposed actions of norepinephrine, renin, ADH, and RAAS.
    • This results in increased preload and afterload, further stressing the cardiovascular system.
    • As HF progresses, perfusion to peripheral and cardiac tissues is impaired, further weakening myocardial tissue.
    • Ultimately, cardiac function becomes inadequate even at rest, leading to increasing activity intolerance.

    Heart Failure Classifications

    • Systolic Failure: Decreased systemic arterial blood volume due to poor ejection volume.
      • Caused by ischemia, infarction, cardiomyopathy, or inflammation.
    • Diastolic Failure: Decreased passive diastolic filling due to incomplete myocardial relaxation.
      • Caused by poor ventricular compliance due to hypertrophy and cellular changes.
    • Left-Sided Failure:
      • Results from coronary heart disease and hypertension.
      • Increased left ventricular pressure obstructs flow back into the left atrium.
      • Increased left atrial pressure slows flow from the pulmonary vasculature.
      • Increased pulmonary pressure leads to fluid moving from the vasculature into the alveoli and interstitial spaces.
      • Manifests as pulmonary congestion and decreased cardiac output.
    • Right-Sided Failure:
      • Caused by reduced blood flow through the pulmonary arterial tree due to left-sided failure.
      • Right side of the heart distends more easily due to thinner myocardium.
      • Congestion in the abdominal organs and edema in the dependent extremities.
    • Pulmonary edema is a consequence of heart failure, not a class of heart failure.

    Low-Output Versus High-Output Failure

    • Low-output failure is primarily caused by cardiac disorders such as coronary artery disease (CAD), hypertension (HTN), and cardiomyopathy.
    • High-output failure is caused by conditions that require increased cardiac output (CO), such as hypermetabolic states like hyperthyroidism, infection, anemia, and pregnancy.
    • High-output failure occurs when increased blood flow cannot meet oxygen demand, and compensatory mechanisms to increase CO are insufficient.

    Acute Versus Chronic Failure

    • Acute heart failure (HF) occurs when a condition or event results in a sudden reduction in cardiac function.
    • Examples of acute HF include myocardial injury such as a massive myocardial infarction.
    • Chronic HF occurs when there is progressive deterioration of heart function.
    • Examples of chronic HF include cardiomyopathies, valvular disease, or coronary heart disease.

    Pulmonary Edema

    • Pulmonary edema can have various causes, including cardiogenic causes.
    • Cardiogenic pulmonary edema occurs when the ejection fraction falls due to impaired left ventricle contractility.
    • This leads to elevated end-diastolic pressure and volume, causing congestion in the pulmonary vasculature.
    • When pulmonary hydrostatic pressure exceeds blood osmotic pressure, intravascular fluid moves into the interstitial space.
    • Increased pulmonary interstitial fluid reduces lung compliance.
    • Congestion of the capillary beds of the alveolar walls impacts gas exchange.
    • Fluid moving into the alveoli further disrupts gas exchange, leading to hypoxia.

    Heart Failure Etiology

    • Heart failure affects 5.7 million Americans (NHLBI, 2020c)
    • Increased risk factors include:
      • Black ethnicity
      • Age 65 and older
      • Overweight
      • History of myocardial infarction (MI)

    Prognosis

    • 5 year survival rate is approximately 50%
    • 10 year survival rate is between 10 and 26% (CDC, 2020b; Yancy et al., 2017)
    • There is no cure, symptoms worsen over time
    • Increased risk of hospitalizations and sudden cardiac death

    Risk Factors

    • Coronary Artery Disease (CAD) is a key risk factor
    • Other risk factors include:
      • Cigarette smoking
      • Obesity
      • Substance abuse
      • Hypertension (HTN)
      • Diabetes (NHLBI, 2020c)

    Other Causes

    • Cardiomyopathy
    • Heart valve disease
    • Dysrhythmias
    • Congenital heart defects
    • Severe lung disease
    • Sleep apnea

    Prevention

    • Control risk factors
    • Follow treatment regimen
    • Patients without heart damage should avoid risky behaviors:
      • Illicit drug use
      • Smoking
    • Engage in health-promoting behaviors:
      • Heart-healthy diet
      • Maintain healthy weight
      • Physical activity
      • Stress reduction (CDC, 2020b, NHLBI, 2020c)
    • High-risk patients should consult with healthcare providers for specific prevention plans and safe exercise recommendations
    • Take all prescribed medications

    Heart Failure Manifestations

    • Heart failure can be caused by systolic or diastolic dysfunction.
    • Systolic heart failure is characterized by reduced pumping ability (decreased cardiac output) leading to:
      • Weakness
      • Fatigue
      • Decreased exercise tolerance
    • Diastolic heart failure is characterized by inability of the heart to properly relax and fill leading to:
      • Shortness of breath (dyspnea)
      • Rapid breathing (tachypnea)
      • Respiratory crackles (left ventricle involvement)
      • Distended neck veins, liver enlargement, anorexia, nausea (right ventricle involvement)
    • Many patients have a mix of both systolic and diastolic failure.

    Left-Sided Heart Failure

    • Early symptoms of left-sided failure are often nonspecific and include:
      • Fatigue
      • Activity intolerance
    • As cardiac output continues to decline:
      • Dizziness
      • Syncope (passing out)
    • Pulmonary congestion due to impeded blood flow leads to:
      • Dyspnea
      • Dry cough
      • Orthopnea, which is dyspnea exacerbated by lying down
    • Signs of left-sided heart failure:
      • Inspiratory crackles on lung auscultation
      • S4 gallop on cardiac auscultation, indicating difficulty filling a stiff ventricle

    Right-Sided Heart Failure

    • Right-sided heart failure affects venous system and increases venous pressure, resulting in:
      • Swelling in lower extremities and around the sacrum (edema)
      • Distended neck veins
    • Venous congestion of the GI tract can cause:
      • Nausea
      • Anorexia
    • Liver congestion can cause:
      • Tenderness or pain over the right upper quadrant

    Additional Manifestations of Heart Failure

    • Salt and water retention in response to reduced CO leads to:
      • Weight gain
      • Increased capillary pressure, causing edema
    • Nocturia (frequent urination at night) occurs as the kidneys are more efficient in excreting water during rest.
    • Paroxysmal nocturnal dyspnea (sudden shortness of breath at night) is caused by fluid reabsorption from the body, leading to fluid overload.
    • In severe heart failure, minimal cardiac reserve remains, resulting in shortness of breath even at rest.

    Heart Failure Complications

    • Venous Congestion: Increased intravascular pressure in the portal venous system due to the heart's compensation efforts leads to congestive hepatomegaly (enlarged liver) and splenomegaly (enlarged spleen).
    • Liver Function: Impaired liver function can result in increased abdominal pressure and ascites (fluid buildup in the abdomen).
    • Cardiomegaly: Enlargement of the heart can trigger dysrhythmias (irregular heartbeats), which reduce cardiac output.
    • Acute Pulmonary Edema: Severe shortness of breath, labored breathing, cool and clammy skin, diaphoresis (excessive sweating), and cyanosis (blue discoloration of the skin) are common symptoms.

    Acute Pulmonary Edema Manifestations

    • Respiratory: Shortness of breath, rapid and shallow respirations, productive cough with pink, frothy sputum, crackles on auscultation, and orthopnea (difficulty breathing lying flat).
    • Cardiovascular: Rapid heart rate, low blood pressure, S3 or S4 heart sounds on auscultation.
    • Neurologic: Agitation, anxiety, confusion, and lethargy as hypoxia worsens.

    Safety Alert

    • Pulmonary edema is a medical emergency. Rapid and effective intervention is crucial to prevent severe tissue hypoxia (oxygen deprivation), acidosis, and organ system failure leading to death.

    Heart Failure (HF) Management

    • Focuses on symptom management to reduce cardiac workload and improve cardiac function.
    • Aims to slow the progression of the disease.

    Diagnosis of Heart Failure

    • Diagnosis of Heart Failure (HF) involves a combination of:
      • Patient history
      • Physical examination
      • Diagnostic findings

    Diagnostic Tests for Heart Failure

    • Natriuretic peptides (ANP and BNP) are hormones released by the heart in response to blood volume changes.
      • Levels increase in HF and are positively correlated with left-ventricular and pulmonary vascular pressure elevations.
      • BNP levels increase as HF symptoms worsen and decrease as the condition stabilizes.
      • Elevated BNP levels in females and those over 60 without a diagnosis of HF are not considered primary diagnostic tools.
    • Serum electrolytes measure elemental substances in the blood (Sodium, Potassium, Chloride, Calcium, Magnesium).
      • These tests evaluate treatment effects.
      • Low serum osmolarity may indicate fluid retention.
    • Urinalysis, BUN, serum creatinine are blood and urine tests evaluating renal function.
    • Liver function tests measure:
      • Alanine aminotransferase (ALT or SGOT)
      • Aspartate aminotransferase (AST or SGPT)
      • Lactate dehydrogenase (LDH)
      • Serum bilirubin
      • Total protein and albumin levels
      • These assess the impact of HF on liver function.
    • Thyroid function tests measure specific components to rule out thyroid dysfunction, which can mimic HF.
    • Arterial blood gas (ABG) analysis evaluates oxygen, carbon dioxide levels, and acid-base balance in the arterial system.
      • Used in acute HF.
    • Chest X-ray visualizes subcutaneous tissues and can detect:
      • Pulmonary vascular congestion
      • Cardiomegaly (enlarged heart)
      • These findings are associated with HF.
    • Electrocardiography (ECG) measures and graphs electrical conduction through the heart.
      • Specific ECG changes are seen with ventricular enlargement.
      • It detects pathophysiologic changes due to dysrhythmia, ischemia, or infarction in the heart.
    • Echocardiography with Doppler flow studies is the gold standard test for HF.
      • Uses sound waves to visualize heart structures and blood flow to evaluate heart function.
      • Can be conducted via transthoracic (on the exterior chest) or transesophageal (positioned in the esophagus) probes.

    Hemodynamic Monitoring Overview

    • Hemodynamics studies the physical forces governing blood circulation.
    • Hemodynamic monitoring is crucial for assessing cardiovascular function in critically ill patients.
    • It uses specialized invasive devices to measure vital signs like heart rate, blood pressure, and central venous pressure.

    Hemodynamic Monitoring Measurements

    • Measures include:
      • Heart rate
      • Arterial blood pressure
      • Central venous or right-atrial pressure
      • Pulmonary pressures (directly measured)
      • Mean arterial pressure
      • Cardiac index
      • Stroke volume
      • Cardiac output (indirectly measured)

    Hemodynamic Monitoring System

    • Quantifies vessel pressure, converting it into a waveform visible on a display.
    • Components include:
      • Invasive catheter connected to a transducer via tubing
      • Continuous flushing system (normal saline or heparinized saline)
      • Stopcock ports for access
      • Pressure cuff for infusion bags

    Types of Measurement

    • Hemodynamic monitoring provides either peripheral artery or central artery pressure measurement.

    Risks of Central Pressure Monitoring

      -  Bleeding
  -  Hematoma formation
  -  Pneumothorax
  -  Hemothorax
  -  Arterial puncture
  -  Dysrhythmia
  -  Venospasm
  -  Infection
  -  Air embolism
  -  Thromboembolism
  -  Brachial or thoracic nerve injury

    Intra-arterial Pressure Monitoring

    • Measures systolic, diastolic, and mean arterial pressure (MAP)
    • Achieved using an indwelling arterial catheter (art line)
    • Provides access for arterial sampling
    • Careful aseptic technique is crucial for managing arterial lines
    • Cardiac output and systemic vascular resistance (SVR) generate arterial blood pressure
    • Systolic blood pressure is the pressure during ventricular systole
    • Diastolic blood pressure reflects the elasticity of arterial walls at minimum pressure
    • MAP is the average arterial circulation pressure across the cardiac cycle
    • Formula for MAP: (Systolic BP + 2 x Diastolic BP) / 3
    • MAP can also be calculated by adding one-third of the pulse pressure (PP) to the diastolic BP (DBP)
    • Desirable MAP range: 70 to 90 mmHg
    • Perfusion is impeded when MAP falls below 50 mmHg
    • Elevated MAP indicates hypertension or a vasoconstrictive state

    Venous Pressure Monitoring

    • Monitors central venous pressure (CVP) and right atrial pressure
    • Measures blood volume, venous return, and right-heart filling pressure
    • Provides accurate assessment of fluid volume status
    • Elevated pressures indicate right-sided heart failure
    • A CVP line is inserted into the internal jugular or subclavian vein, with the tip positioned in the superior vena cava
    • Normal CVP range: 2 to 8 cm H2O or 2 to 6 mmHg
    • Range can vary with hypovolemia/shock (decreased CVP) or fluid overload/vasoconstriction (increased CVP)

    Pulmonary Artery Pressure Monitoring

    • Uses a pulmonary artery catheter (Swan-Ganz catheter)
    • Contains multiple lumens for pressure measurement and drug delivery
    • Inserted through a central vein to the right atrium
    • Advanced into the right ventricle and then the pulmonary artery
    • Normal pulmonary artery pressure: approximately 25/10 mmHg
    • Normal mean pulmonary artery pressure: approximately 15 mmHg
    • Increased pulmonary artery pressure indicates left-sided heart failure
    • Pulmonary artery wedge pressure (PAWP) indirectly measures left-ventricular function
    • Normal PAWP: 8 to 12 mmHg
    • PAWP is increased in left-ventricular failure and pericardial tamponade, and it is decreased in hypovolemia

    Pharmacologic Therapy for Heart Failure

    • Multiple drugs are used to treat heart failure (HF), each targeting different aspects of the disease.

    • ACE inhibitors block the conversion of angiotensin I to angiotensin II, causing vasodilation and reducing cardiac work.

    • ARBs directly block the binding of angiotensin II to receptors, achieving similar effects as ACE inhibitors.

    • Beta-adrenergic blockers inhibit the sympathetic nervous system (SNS), improving failing heart function. Low doses are used to avoid worsening symptoms.

    • Diuretics are used to alleviate fluid overload. They can lead to rapid fluid loss and electrolyte imbalance, requiring careful monitoring.

    • Vasodilators, such as nitrates and hydralazine, relax blood vessels, reducing afterload and improving fluid reabsorption. They may also reduce venous return.

    • Cardiac glycosides (digitalis) have a limited role in HF treatment due to their narrow therapeutic index. They increase myocardial contractility but pose a risk of toxicity.

    • BiDil, a combination of hydralazine and isosorbide dinitrate, has been shown to benefit Black patients with HF.

    Specific Drug Information

    • Loop diuretics (furosemide, bumetanide) are commonly used due to their rapid onset of action.

    • Potassium-sparing diuretics are favored for long-term treatment of CHF.

    • Digitalis toxicity can lead to gastrointestinal distress, neurologic changes, and life-threatening cardiac dysrhythmias.

    • Careful monitoring and consideration of drug interactions are vital when using digitalis.

    Angiotensin-Converting Enzyme (ACE) Inhibitors

    • Examples: captopril, enalapril (Vasotec), fosinopril, lisinopril (Prinivil, Zestril), quinapril (Accupril), ramipril (Altace), trandolapril
    • Interfere with the enzyme that converts angiotensin I to angiotensin II, causing vasodilation, reduced blood pressure, and prevention of its effects in the heart and blood vessels.
    • ACE inhibitors reduce afterload, improve cardiac output, and renal blood flow in heart failure (HF).
    • They also reduce pulmonary congestion, peripheral edema, and suppress myocyte growth, reducing ventricular remodeling in HF.
    • Contraindicated in the second and third trimesters of pregnancy.
    • Carefully monitor patients with volume depletion or impaired renal function.
    • Use an infusion pump for intravenous administration.
    • Monitor BP closely for 2 hours after the first dose and as indicated thereafter.
    • Monitor serum potassium levels for potential hyperkalemia.
    • Monitor WBC count for potential neutropenia.

    Angiotensin II Receptor Blockers (ARBs)

    • Examples: candesartan (Atacand), valsartan (Diovan)
    • Block the action of angiotensin II at the receptors on arteries instead of interfering with its production.
    • Monitor for headache, dizziness, orthostatic hypotension, rash, and diarrhea.
    • Contraindicated in pregnancy.

    Beta-Adrenergic Blockers (Antagonists)

    • Examples: carvedilol (Coreg), metoprolol (Lopressor, Toprol XL)
    • Block the cardiac actions of the sympathetic nervous system (SNS) to slow heart rate and reduce blood pressure.
    • Abrupt withdrawal not advised.
    • Monitor BP and pulses.

    Cardiac Glycosides

    • Example: digoxin (Digitek, Lanoxin)
    • Improves myocardial contractility by interfering with ATP in the myocardial cell membrane, increasing calcium available for contraction.
    • This increases force of contraction, causing the heart to better empty, increasing stroke volume and cardiac output.
    • Improved cardiac output improves renal perfusion, decreasing renin secretion, reducing preload and afterload, and reducing cardiac work.
    • It also slows conduction through the AV node, decreasing heart rate and oxygen consumption
    • Nursing Considerations:
      • Assess apical pulse before administering.
      • Withhold digoxin and notify the provider if heart rate is below 60 bpm or there are signs of decreased cardiac output.
      • Record apical rate on medication record.
      • Evaluate the ECG for significant changes.
      • Report manifestations of digitalis toxicity: anorexia, nausea and vomiting, abdominal pain, weakness, vision changes (e.g., diplopia, blurred vision, yellow-green or white halos seen around objects), and new-onset dysrhythmias.
      • Monitor potassium, magnesium, calcium, and serum digoxin levels.
      • Hypokalemia can precipitate toxicity, even if the serum digoxin level is within the normal range (adult: 0.5–2 ng/mL, 0.5–2 nmol/L [SI units]; infants: 1–3 ng/mL).
      • Monitor patients with renal insufficiency or failure, and older adults closely for digitalis toxicity.
      • Prepare to administer digoxin immune Fab (DigiFab) for digoxin toxicity.

    Diuretics

    • Examples: amiloride, eplerenone (Inspra), spironolactone (Aldactone), triamterene (Dyrenium)
    • Act on different portions of the kidney tubule to inhibit reabsorption of sodium and water and promote excretion.
    • All are potassium-sparing diuretics, used to treat edema associated with CHF.
    • Eplerenone and spironolactone are aldosterone receptor blockers, which reduce symptoms and slow progression of HF.
    • Aldosterone receptors promote myocardial remodeling and fibrosis, activate the SNS, and promote vascular fibrosis (decreased vascular compliance) and baroreceptor dysfunction.
    • Nursing Considerations:
      • Obtain baseline weight and vital signs.
      • Monitor BP, intake and output, weight, skin turgor, and edema.
      • Assess for volume depletion: dizziness, orthostatic hypotension, tachycardia, and muscle cramping.
      • Report abnormal serum electrolyte levels to the HCP, and replace electrolytes as indicated.
      • Do not administer potassium replacements to patients on potassium-sparing diuretics.
      • Evaluate renal function by assessing urine output, BUN, and serum creatinine.

    Phosphodiesterase-3 Enzyme Inhibitors

    • Example: milrinone (Primacor)
    • Treats acute HF to increase myocardial contractility and cause vasodilation.
    • Net effects are an increase in cardiac output and a decrease in afterload.
    • Nursing Considerations:
      • Use an infusion pump to administer.
      • Monitor hemodynamic parameters carefully.
      • Avoid abrupt discontinuation of the drug.
      • Change solutions and tubing every 24 hours.

    Vasodilators

    • Examples:
      • hydralazine with isosorbide dinitrate (BiDil)
      • nesiritide
      • sacubitril/valsartan (Entresto)
    • Hydralazine with isosorbide dinitrate relaxes blood vessels and lowers BP.
    • Nesiritide causes vasodilation, reducing preload.
    • Sacubitril/valsartan inhibits the RAAS and increases levels of atrial natriuretic peptides.
    • Nursing Considerations:
      • Monitor BP, peripheral pulses, and urinary output.
      • These drugs may cause severe hypotension.
      • Nesiritide is administered intravenously.
      • Monitor for dysrhythmias.
      • Nesiritide may cause dysrhythmias
      • Do not use sacubitril/valsartan in pregnant women.

    Black Patients and Heart Failure

    • Black patients are more likely to experience heart failure (HF) symptoms, have more hospital stays related to HF, and are more likely to die from HF than other racial groups.
    • Atherosclerotic risk factors, high blood pressure (BP), obesity, and diabetes disproportionately affect Black patients, increasing their risk for HF.
    • Black patients tend to develop HF at younger ages, are more likely to have renal insufficiency, and have poorly controlled hypertension compared to others with HF.
    • Black patients often have lower ejection fractions at diagnosis than other races.
    • Common HF treatments like diuretics, vasodilators, and other medications are used for Black patients.
    • Black patients respond favorably to isosorbide dinitrate and hydralazine, often administered together as BiDil, a medication specifically used for Black patients with HF.
    • Discharge planning is crucial, including education about diet, exercise, medication, symptom recognition, and timely medical care.

    Antidysrhythmics and Heart Failure

    • Many patients with Heart Failure (HF) experience dysrhythmias.
    • Premature Ventricular Contractions (PVCs) are common but not associated with an increased risk of Ventricular Tachycardia (VT) or fibrillation.
    • Most antidysrhythmics negatively affect left ventricular function, making their use in HF uncommon.
    • Amiodarone is the preferred medication for nonsustained VT, which has a poor prognosis.

    Nutrition and Activity in Heart Failure

    • Sodium and fluid retention are common in HF due to the underlying pathophysiological changes.
    • A sodium-restricted diet, limiting intake to 1.5-2 grams per day, is recommended to minimize these retentions.
    • Exercise intolerance is an early symptom of HF.
    • Moderate, progressive aerobic exercise is encouraged, and cardiac rehabilitation is indicated for patients with HF.
    • Prolonged bed rest and avoidance of activity are discouraged as they lead to further weakening and worsening symptoms.

    Surgery for Heart Failure

    • There is no surgical procedure to reverse heart failure progression.
    • Patients with heart failure secondary to other cardiovascular diseases, such as valvular disease, may be candidates for surgery.
    • Heart transplantation is an option for select patients, however, limited donor heart availability restricts widespread use.

    Circulatory Assistance Devices

    • Circulatory assist devices are available for patients with heart failure who are expected to recover or as a bridge to cardiac transplantation.
    • The Intra-Aortic Balloon Pump (IABP) requires intensive care due to insertion via the femoral artery.
    • The Left Ventricular Assist Device (LVAD) requires a specialized team, but can be supported outside of the hospital.

    Cardiac Transplantation

    • Heart transplantation is the primary treatment for end-stage heart disease.
    • Over 90% of patients survive for 1 year after transplantation, and 77% survive for 5 years after transplantation.
    • During heart transplantation, the posterior walls of the atria, vena cavae, and pulmonary veins are preserved.
    • The atrial walls of the donor heart are then connected to the recipient's atria.
    • The donor pulmonary artery and aorta are connected to the recipient vessels.

    Postoperative Care

    • Similar to any cardiac surgery patient care
    • Bleeding is a major concern, chest tubes are monitored closely.
    • Cardiac hemodynamics are monitored
    • Cardiac tamponade may develop
      • Can either occur suddenly or gradually
    • Atrial dysrhythmias can develop post surgery
      • Temporary pacing wires are placed during surgery
      • Can be caused by surgical manipulation or postoperative swelling
    • Postoperative rewarming is gradual over 1 to 2 hours to avoid shivering and reduce oxygen consumption
    • Cardiac function is impaired in up to 50% of hearts in the early postoperative period
      • Patients may be placed on inotropic agents to support the heart

    Post-transplant Concerns

    • Infection and rejection are the major concerns
    • Rejection may develop at any time after transplantation
      • Acute rejection typically presents within weeks
      • Symptoms of acute rejection: lymphocytes infiltrate the organ and myocardial cell necrosis occurs
      • Detected through biopsy
    • Immunosuppressive therapy is started post surgery to help prevent rejection.
      • Patients will remain on one to three immunosuppressive drugs for life
    • Infection control is critical due to the increased risk of infection with immunosuppressive drugs
      • Strict hygiene practices are needed to minimize exposure to exogenous pathogens
    • Donor hearts are denervated during the transplant procedure
      • Heart rate variability changes, resulting in a high-normal heart rate of 90 to 110 beats per minute.

    End-of-Life Care

    • Chronic HF is a terminal disease
    • Patients and families need honest conversations about the course of the disease and treatment options
    • Advance directives should be discussed, such as living wills and healthcare power of attorney
    • Hospice services should be offered to patients with HF when appropriate
    • Severe dyspnea is common in the final stages of the disease
      • Treatment is symptomatic and may involve narcotic analgesics, diuretics, positioning, and anxiety reduction
      • Decreasing exertion may also be helpful

    Heart Failure in Different Lifespans

    • Heart failure (HF) is most common in people aged 65 and older.
    • Risk factors for HF at any age: overweight, heart attack, and being Black.
    • HF in children can be caused by congenital heart defects.
    • Types of HF in children:
      • Overcirculation failure: overload blood flow in one or more heart sections.

      • Myocardial fibrosis due to RAAS changes, inflammation, and oxidative stress.
    • Symptoms of HF in older adults:
      • Gradual onset, often accompanied by decreased appetite and weight loss.
      • Shortness of breath can be attributed to other age-related conditions.
    • Treatment of HF in older adults: similar to the general population but efficacy might be compromised due to underrepresentation in clinical trials.
    • Concerns with treatment in older adults: drug interactions and nonadherence.

    Heart Failure Risk Reduction

    • Lifestyle changes can significantly reduce the risk and occurrence of heart failure.
    • Smoking cessation and substance abuse recovery programs are crucial interventions.
    • Coronary heart disease, a primary cause of heart failure, should be understood by patients.
    • Discussing coronary artery disease risk factors with both patients and caregivers is essential for prevention.
    • Hypertension, a major contributor to heart failure, necessitates screening and referral to a primary healthcare provider.
    • Effective hypertension management is crucial for reducing the future risk of heart failure.
    • Patients with diabetes should be educated on the link between effective diabetes management and reduced heart failure risk.

    Heart Failure Management

    • Heart failure can significantly impact activity tolerance, diminishing quality of life.
    • Nursing care prioritizes oxygen demand reduction through balanced activity and rest.
    • Patient education on recognizing worsening symptoms includes daily blood pressure monitoring, weight tracking, nutrition guidance, medication comprehension, and activity planning.

    Heart Failure Assessment

    • Observation and Interview:
      • Review history of cardiac disease or past heart failure episodes.
      • Discuss other risk factors such as hypertension or diabetes.
      • Assess diet and activity levels, including activity tolerance and dyspnea with exertion.
      • Inquire about paroxysmal nocturnal dyspnea and pillow usage during sleep.
      • Investigate recent weight changes, anorexia, or nausea.
      • Review current medications.
      • Observe for shortness of breath, cough, chest or abdominal pain, and ease of breathing, conversing, and changing positions.
    • Physical Examination:
      • Assess vital signs, including apical and peripheral pulses.
      • Evaluate general appearance, skin and mucous membrane color, and neck vein distention.
      • Assess capillary refill.
      • Note the presence and extent of edema.
      • Auscultate heart sounds, breath sounds, and bowel sounds.
      • Palpate the abdomen for contour, tenderness, and liver enlargement.
      • Observe for signs of anxiety.

    Heart Failure (HF) Patient Diagnosis Problems

    • Decreased Cardiac Output (CO): The heart struggles to pump blood effectively, resulting in reduced blood flow to the body.
    • Fluid Volume Excess: The body retains fluid, leading to swelling (edema) in the legs, ankles, and lungs.
    • Intolerance to Activity: Even minimal physical exertion can cause shortness of breath and fatigue.
    • Lack of Knowledge about HF: Patients may be unaware of the condition, its causes, and management strategies.

    Heart Failure (HF) Patient Care Goals

    • Medication Understanding: Patients should be able to explain the purpose of each prescribed drug.
    • Symptom Reporting: Patients should know which symptoms to report to their healthcare provider (HCP).
    • Oxygenation Maintenance: Patients require adequate oxygen levels, monitored through respiratory status, breath sounds, oxygen saturation, and vital signs.
    • Tissue Perfusion and Myocardial Function: Proper blood flow and heart function are essential, assessed through capillary refill, hemodynamic monitoring, pulse assessment, and vital signs.
    • Nutritional Needs: Patients must meet their body's energy demands through appropriate and sufficient nutrition.

    Heart Failure (HF) Nursing Interventions

    • Promoting Perfusion and Oxygenation: Nursing care focuses on improving blood flow and oxygen levels.
    • Addressing Fear and Anxiety: A heart condition can generate significant fear of death and disability. Providing support and information to both the patient and family is crucial.
    • Managing Anxiety from Hypoxia: Nursing interventions address anxiety associated with low oxygen levels.

    Maintaining Cardiac Output

    • Elevate the head of the bed to reduce the work of breathing.
    • Monitor vital signs, especially heart rate, which may indicate sympathetic nervous system stimulation due to low cardiac output (CO).
    • Monitor oxygen saturation, as it provides a measure of gas exchange and tissue perfusion.
    • Monitor BNP levels, which indicate the severity of heart failure (HF) and increase with progressive HF.
    • Auscultate the heart and lungs. Diminished heart sounds may indicate poor cardiac function. Basilar crackles and dyspnea suggest worsening HF.
    • Administer supplemental oxygen as ordered for hypoxia.
    • Administer prescribed medications to decrease cardiac workload, increase contractility, and promote sodium and fluid excretion.

    Monitoring Fluid Volume

    • Assess respiratory status every 4 hours. Declining respiratory status indicates worsening left HF.
    • Monitor intake and output, and notify the healthcare provider if urine output is less than 30 ml/hr.
    • Monitor weight daily at the same time. A 1-liter increase in fluid equals a 2.2-pound weight gain.
    • Record abdominal girth every shift as an objective measure of fluid retention.
    • Assess for loss of appetite, abdominal discomfort, or nausea, as venous congestion can lead to ascites and affect GI function.
    • Monitor and record hemodynamic measurements such as pulse and blood pressure.
    • Monitor and restrict fluids as ordered.
    • Allow choices regarding fluid type and timing of intake, scheduling most fluids during the morning and afternoon.
    • Provide ice chips and mouth care for dry mouth and thirst.

    Monitoring Activity

    • Organize care to allow for rest periods between interventions.
    • Assist the patient with activities of daily living (ADLs) as needed, while encouraging independence within prescribed limits.
    • Work with physical therapists to plan and implement progressive activities.
    • Use passive and active range of motion (ROM) exercises to prevent skeletal muscle atrophy and complications of immobility.
    • Provide written and verbal information about activity after discharge and teach energy conservation techniques.
    • Consider home healthcare referrals.
    • Consult with a registered dietitian for dietary instruction and a social worker for assistance with household needs.
    • Refer to community resources, such as cardiac rehabilitation programs and support groups.

    Heart Failure and Diet

    • Low-sodium diet is essential for managing fluid retention in heart failure.
    • Discuss rationale for sodium restrictions with patients to improve dietary compliance.
    • Consult a dietitian to plan and teach low-sodium diet, and address any other dietary needs.
    • Provide materials from the American Heart Association (AHA) to support dietary planning and teaching.
    • Dietary planning and teaching empower patients and enhance their sense of control in managing their condition.

    Discharge Planning for Heart Failure

    • Discuss the disease process and its impact on daily life with patients and families.
    • Explain early symptoms of cardiac decompensation:
      • Weight gain
      • Increased shortness of breath
      • Edema
      • Orthopnea
    • Educate patients and families about medication effects and side effects to monitor.
    • Emphasize the importance of adhering to the prescribed therapeutic diet, including sodium and fluid restrictions.
    • Utilize AHA materials and consider a nutrition consult.
    • Provide guidance on home activity guidelines, including aerobic exercise recommendations to strengthen the heart muscle.
    • Reinforce follow-up medical appointments for managing chronic disease and symptoms.

    Evaluation of Patient Progress

    • Patients should be able to describe each prescribed medication and the symptoms that warrant immediate reporting to their healthcare provider.
    • Patients should understand the importance of daily weight monitoring, keeping a weight log, and reporting significant weight gain.
    • Patients should be able to choose appropriate low-sodium foods from a menu.
    • Patients should be able to adjust their daily routine to accommodate adequate periods of rest and activity.
    • Noncompliance with treatment regimens can lead to rapid changes in patient condition and hospitalization.
    • Identify the cause of noncompliance and develop a care plan addressing the underlying issues when patients fail to adhere to dietary restrictions or medication regimens.

    Heart Failure Overview

    • Heart failure (HF) is a chronic condition where the heart cannot pump enough blood to meet the body's needs.
    • This can be caused by problems with heart contraction (systolic failure) or filling (diastolic failure).
    • HF can happen in the left ventricle, right ventricle, or both.

    Pathophysiology of Heart Failure

    • Reduced cardiac output (CO) leads to decreased blood flow and oxygen delivery to tissues.
    • Stroke volume (SV) and CO are both affected as HF worsens.

    Compensatory Mechanisms in HF

    • The Frank-Starling mechanism increases contraction strength initially but prolonged stretch causes overstretching and decreased contractility.
    • The sympathetic nervous system (SNS) increases heart rate and vasoconstriction to temporarily raise CO but also increases oxygen demand.
    • The renin-angiotensin-aldosterone system (RAAS) causes vasoconstriction, sodium, and water retention, increasing preload. Prolonged activation leads to fluid overload, high blood pressure, and cardiac stress.

    Myocardial Hypertrophy and Remodeling

    • The heart muscle thickens and stiffens (hypertrophy), and the ventricles dilate.
    • This helps maintain CO temporarily but worsens HF due to increased myocardial oxygen demand and fibrosis.

    Left vs. Right-Sided Heart Failure

    • Left-sided HF: Commonly due to hypertension and coronary artery disease, leading to pulmonary congestion and symptoms like dyspnea and orthopnea.
    • Right-sided HF: Usually due to left-sided HF or pulmonary problems, leading to venous congestion and symptoms like edema and ascites.

    Progression and Exacerbation of HF

    • HF can worsen as compensatory mechanisms fail, leading to decreased exercise tolerance, fluid retention, and ultimately symptoms even at rest.

    Diagnostic Markers in HF

    • Brain natriuretic peptide (BNP): Elevated BNP levels are associated with HF severity. It is released when the ventricle stretches.
    • Ejection fraction (EF): Measured by echocardiography, it helps determine HF type. Reduced EF is linked to systolic HF and preserved EF to diastolic HF.

    Common Triggers of HF Exacerbation

    • Poor medication adherence, high sodium intake, unmanaged hypertension, and concurrent illness can worsen HF symptoms.

    Treatment Goals for HF

    • Reduce cardiac workload, manage fluid retention, control symptoms, and prevent disease progression.
    • Medications like ACE inhibitors, beta-blockers, and diuretics are commonly used.

    Primary Risk Factors for HF

    • Coronary Artery Disease (CAD): Blocked or narrowed coronary arteries restrict blood flow to the heart, increasing the risk of heart failure.
    • Hypertension (HTN): Chronic high blood pressure forces the heart to work harder, leading to hypertrophy and eventual heart muscle weakening.
    • Diabetes: Increases the risk of CAD, contributes to high blood pressure, and can directly impair heart muscle function.
    • Heart Attack (Myocardial Infarction): Damaged heart tissue from a previous MI can impair the heart's pumping ability, leading to HF.
    • Obesity: Excess weight increases the heart's workload and is often associated with hypertension and diabetes, both of which increase HF risk.
    • Valvular Heart Disease: Valve disorders cause blood flow irregularities, increasing heart workload and predisposing it to failure.
    • Age (65 and Older): HF prevalence rises with age due to age-related changes in cardiac function and increased risk of other contributing conditions.
    • Gender and Race: HF is more prevalent in men under age 65 but increases in women post-menopause. Black patients are at higher risk and often experience more severe HF symptoms and complications.

    Contributing (Secondary) Risk Factors

    • Chronic Kidney Disease (CKD): Leads to fluid and electrolyte imbalances, increasing the heart's workload and raising the risk of heart failure.
    • Sleep Apnea: Obstructive sleep apnea (OSA) can lead to intermittent hypoxia, increasing blood pressure and putting strain on the heart.
    • Preeclampsia and Pregnancy-Related Conditions: Conditions like peripartum cardiomyopathy and preeclampsia increase HF risk in pregnant women.
    • Substance Use (Alcohol and Drugs): Excessive alcohol intake and illicit drugs (like cocaine) can lead to cardiomyopathy and HF.
    • Smoking: Damages blood vessels, contributes to CAD, worsens HTN, and increases HF risk.
    • Sedentary Lifestyle: Lack of physical activity is associated with obesity, HTN, and diabetes, all of which are HF risk factors.

    Preventive Measures for HF Risk Factors

    • Controlling blood pressure and cholesterol
    • Maintaining a healthy weight and diet
    • Managing diabetes
    • Quitting smoking and limiting alcohol intake
    • Staying physically active

    Assessment in Heart Failure

    • Medical History - Questions should revolve around a history of cardiac disease, previous episodes of heart failure, and other cardiovascular conditions.
    • Risk Factors - Assess for hypertension, diabetes, obesity, smoking, and other known HF risk factors. Explore patient activity levels and lifestyle choices.
    • Symptoms and Activity Tolerance - Inquire about shortness of breath, fatigue, and activity intolerance which are common in HF due to reduced cardiac output. Document any recent weight gain or loss, which could indicate fluid retention or loss of appetite.
    • Appetite and Gastrointestinal Symptoms - Inquire about potential loss of appetite, nausea, and abdominal discomfort. These may be due to venous congestion affecting the gastrointestinal tract.
    • Medication Adherence - Evaluate prescribed medications, over-the-counter drugs, and supplements. Inquire about adherence to medication and if they are experiencing any side effects.
    • Observation of Patient Condition - Note signs of shortness of breath, cough, and difficulty speaking or moving due to dyspnea. Observe for swelling in the extremities or abdomen, as this can indicate fluid retention. Evaluate the patient’s mental state for signs of anxiety or confusion, which may be linked to hypoxia.
    • Vital Signs - Check heart rate for tachycardia and blood pressure for hypertension or hypotension. Assess oxygen saturation to gauge gas exchange and tissue perfusion.
    • General Appearance and Skin - Observe skin color and temperature—pale, cool, or clammy skin can indicate poor perfusion. Assess for cyanosis (bluish tint) on lips, fingers, or toes, which suggests low oxygen levels.
    • Neck Veins - Check for jugular vein distention (JVD), a sign of increased central venous pressure and potential right-sided heart failure.
    • Edema - Examine for peripheral edema in the ankles, legs, or sacral area and assess its severity. Measure and document abdominal girth if ascites is suspected.
    • Auscultation
      • Heart Sounds - Listen for abnormal sounds such as S3 (ventricular gallop), which is common in HF and may indicate fluid overload, or S4, indicating a stiff ventricle.
      • Lung Sounds - Check for basilar crackles or rales, especially in the bases of the lungs. These sounds indicate pulmonary congestion.
      • Bowel Sounds - Abnormal sounds or a distended abdomen can suggest gastrointestinal congestion due to right-sided HF.
    • Peripheral Pulses and Capillary Refill - Palpate peripheral pulses to assess circulation. Weak or diminished pulses can indicate low CO. Check capillary refill time in the fingers and toes; delayed refill (>2 seconds) may indicate poor perfusion.
    • Abdomen - Palpate the abdomen for tenderness, liver enlargement (hepatomegaly), or signs of ascites. These findings suggest venous congestion, commonly seen in right-sided HF.
    • Signs of Anxiety and Restlessness - Assess for anxiety or restlessness, which may be secondary to hypoxia or an indication of worsening HF.
    • Assessment Goals in HF
      • The goal of the assessment is to gather both subjective and objective data to evaluate the extent of HF, identify any potential complications, and guide subsequent interventions.
      • The information from the interview and physical exam provides a comprehensive picture of the patient’s condition and helps direct nursing care and medical treatment.

    BNP and NT-proBNP

    • BNP and NT-proBNP are hormones released by the heart in response to ventricular stretch and increased pressure.
    • Higher levels indicate worsening heart failure (HF).
    • BNP values are categorized to estimate HF severity:
      • < 100 pg/mL: Unlikely HF
      • 100–300 pg/mL: HF possible, especially if symptomatic

      • 300 pg/mL: Mild HF

      • 600 pg/mL: Moderate HF

      • 900 pg/mL: Severe HF

    • NT-proBNP values are age-specific:
      • < 50 years: < 450 pg/mL suggests HF is unlikely
      • 50–75 years: < 900 pg/mL suggests HF is unlikely

      • 75 years: < 1800 pg/mL suggests HF is unlikely

    • Elevated BNP/NT-proBNP levels correlate with more severe HF and are useful for monitoring HF progression and treatment efficacy.

    Echocardiography

    • Uses ultrasound to visualize the heart, measure ejection fraction (EF), and assess ventricular function, valve integrity, and chamber size.
    • Ejection Fraction (EF):
      • Normal EF: 50–70%
      • Borderline EF: 41–49% (suggestive of mild impairment)
      • Reduced EF: ≤ 40% (systolic heart failure)
    • Low EF (≤ 40%) is typical in systolic HF.
    • Preserved EF with HF symptoms may indicate diastolic HF.
    • Other findings like enlarged ventricles, abnormal valve function, and ventricular wall motion abnormalities can support an HF diagnosis and guide treatment.

    Chest X-Ray

    • Visualizes heart size, pulmonary congestion, and fluid in the lungs.
    • Key Findings:
      • Cardiomegaly: Enlarged heart silhouette, indicating an enlarged heart due to HF.
      • Pulmonary Edema: Cloudy or “fluffy” appearance in lung fields, suggesting fluid accumulation.
      • Kerley B lines: Horizontal lines at the lung periphery, indicating interstitial edema from fluid overload.
    • An enlarged heart and evidence of pulmonary congestion suggest HF, especially if the patient is symptomatic.

    Electrocardiogram (ECG)

    • Assesses the heart’s electrical activity, helping detect arrhythmias, ischemia, or left ventricular hypertrophy commonly associated with HF.
    • Key Findings:
      • Q waves: Sign of previous myocardial infarction (MI) that could have led to HF.
      • Atrial or Ventricular Hypertrophy: Increased voltage patterns can indicate chamber enlargement from HF.
      • Arrhythmias: Atrial fibrillation (AFib) is common in HF patients and can worsen symptoms.
    • Abnormal ECG findings alone don’t diagnose HF, but they often accompany HF, particularly when combined with other clinical signs

    Complete Blood Count (CBC)

    • May reveal anemia or infection, both of which can exacerbate HF symptoms.
    • Key Values:
      • Hemoglobin (Hgb): Low Hgb levels (< 12 g/dL in women, < 13 g/dL in men) indicate anemia, which can worsen HF symptoms by reducing oxygen delivery to tissues.
      • White Blood Cell (WBC) Count: Elevated WBCs (> 10,000 cells/µL) can indicate infection, which may stress the heart further.
    • Identifying anemia or infection helps in managing HF by treating contributing factors that can worsen heart function.

    Serum Electrolytes and Renal Function Tests

    • Provide insight into fluid balance, kidney function, and potential complications of HF medications like diuretics.
    • Key Values:
      • Sodium (Na): Normal range is 135–145 mEq/L. Hyponatremia (< 135 mEq/L) may indicate fluid overload.
      • Potassium (K): Normal range is 3.5–5.0 mEq/L. Hypokalemia or hyperkalemia may occur from diuretic use and affect heart rhythm.
      • Creatinine: Normal is 0.6–1.2 mg/dL. Elevated levels suggest renal impairment (common in advanced HF).
    • Electrolyte imbalances and renal dysfunction are common in HF and need close monitoring, especially with diuretic therapy.

    Arterial Blood Gases (ABG)

    • Evaluates oxygenation, carbon dioxide levels, and acid-base balance, especially in acute HF with respiratory distress.
    • Key Values:
      • PaO2: Normal is 80–100 mmHg. Low levels indicate poor oxygenation.
      • PaCO2: Normal is 35–45 mmHg. Elevated levels (> 45 mmHg) indicate hypoventilation.
      • pH: Normal is 7.35–7.45. Low pH (< 7.35) suggests acidosis, which can occur in HF due to tissue hypoxia and lactic acid build-up.
    • Low oxygen levels and acid-base imbalances are signs of severe HF with respiratory compromise.

    Thyroid Function Tests

    • Hyperthyroidism or hypothyroidism can contribute to HF.
    • Thyroid function tests rule out these conditions in HF patients
    • Key Values:
      • TSH (Thyroid-Stimulating Hormone): Elevated in hypothyroidism, low in hyperthyroidism.
      • Free T4: Abnormal levels indicate thyroid dysfunction
    • Managing thyroid abnormalities is crucial, as they can exacerbate HF symptoms.

    Liver Function Tests

    • Liver function can be affected by right-sided HF due to congestion in the venous system, impacting blood flow to the liver.
    • Key Values:
      • ALT (Alanine Aminotransferase) and AST (Aspartate Aminotransferase): Elevated levels indicate liver stress or damage.
      • Bilirubin: Elevated levels suggest liver congestion.
    • Abnormal liver function tests indicate venous congestion and may be present in right-sided HF.

    ### Pharmacologic Interventions

    • ACE Inhibitors (e.g., Lisinopril, Enalapril) inhibit the conversion of angiotensin I to II, causing vasodilation and reducing workload on the heart
      • Benefits: Improve cardiac output and reduce fluid overload
      • Considerations: Monitor blood pressure and potassium levels

    Heart Failure in Children

    • Heart failure in children is often caused by congenital heart defects or acquired heart conditions.
    • Congenital heart defects cause excess strain on the heart.
    • Overcirculation failure: Occurs when there is increased blood flow in specific heart sections, leading to poor pumping efficiency.
    • Pump failure: Valve or structural defects increase pressure within the heart chambers, impacting the heart's ability to pump effectively.
    • Rare causes include severe trauma or myocarditis (inflammatory heart disease).
    • Children with heart failure might present with difficulty breathing, excessive sweating, low blood pressure, poor feeding, and slow growth.
    • Edema (swelling) is less prominent in children compared to adults.
    • Diagnosis: Similar to adults, BNP levels, echocardiography, and other imaging studies are used to diagnose heart failure.
    • Treatment includes surgery (valve replacement, defect repair), mechanical supports (pacemakers or ventricular assist devices), and medications (diuretics, afterload reducers like ACE inhibitors).
    • Medications are carefully calculated based on body weight.
    • Treatment must balance symptom management while minimizing impact on growth and development.
    • Compensated heart failure: Some children achieve stability after initial treatment, but the underlying condition may persist.
    • Regular follow-up is crucial to monitor heart function, growth, and development.

    Heart Failure in Pregnancy

    • Cardiac output (CO) increases by 30-50%, blood volume rises by 40-50%, and both heart rate and stroke volume increase during pregnancy.
    • These changes place additional strain on the heart.
    • Women with preexisting heart failure, especially stage III or IV or with a low ejection fraction, are at higher risk of decompensation during pregnancy.
    • Pregnancy is generally discouraged for women with advanced heart failure (stage III/IV) or an ejection fraction below 40%.
    • Symptoms of heart failure during pregnancy include dyspnea (shortness of breath), fatigue, and fluid retention, which can be easily mistaken for normal pregnancy symptoms.
    • Medications:
      • ACE inhibitors and ARBs are contraindicated due to teratogenic effects (harmful to the fetus).
      • Diuretics can be used cautiously for fluid overload but require careful monitoring to prevent electrolyte imbalances.
      • Beta-blockers can be used but carry risks, like intrauterine growth restriction.
    • Close monitoring during pregnancy and postpartum is vital for worsening heart failure symptoms.
    • Alternative therapies include compression stockings and reduced sodium intake to manage fluid retention.

    Peripartum Cardiomyopathy

    • Heart failure that develops during the last trimester of pregnancy or shortly after delivery.
    • Often requires long-term monitoring and treatment.
    • May improve postpartum, but symptoms persist for some women.
    • Postpartum care requires careful monitoring due to the sudden decrease in blood volume after delivery.
    • This can exacerbate heart failure symptoms.

    Heart Failure in Older Adults

    • Heart failure prevalence increases with age.
    • Common causes include hypertension, coronary artery disease, diabetes, and valvular diseases.
    • Aging contributes to myocardial cell loss, fibrosis, and reduced heart function.
    • Older adults often experience gradual symptom onset, including fatigue, weight loss, and decreased appetite.
    • Shortness of breath and edema may be attributed to other age-related conditions, delaying diagnosis.
    • Treatment considerations:
      • Similar medications are used as with younger adults, but with careful monitoring due to increased sensitivity to medications and drug-drug interactions.
      • Older adults are more susceptible to side effects like hypotension and electrolyte imbalances.
      • Polypharmacy (multiple medications) increases the risk of adverse drug interactions, especially with diuretics, ACE inhibitors, and beta-blockers.
      • Dosing adjustments may be necessary to prevent adverse effects.
    • Additional support needs:
      • Cognitive and physical support for medication adherence, monitoring, and understanding symptoms.
      • Access to home healthcare services, physical therapy, and nutritional support may be necessary to manage heart failure effectively.
    • Activity and lifestyle modifications:
      • Gentle, supervised physical activities are encouraged to improve endurance without overexerting the heart.
      • A low-sodium diet is essential, but sensory changes or financial limitations may impact diet quality.
    • End-of-life care:
      • Palliative care can help manage symptoms and improve quality of life in advanced stages.
      • Discussing goals of care, advanced directives, and treatment limitations (e.g., resuscitation preferences) is crucial in heart failure management for older adults.
    • Summary of Lifespan Considerations:
      • Children: Focus on managing congenital defects and promoting normal growth and development. Tailored medications with an emphasis on preventing long-term complications.
      • Pregnant Women: High risk of decompensation due to increased CO and blood volume. Contraindications for ACE inhibitors and ARBs; cautious use of diuretics and beta-blockers.
      • Older Adults: Age-related changes complicate heart failure management, increasing sensitivity to medications and the need for support. Polypharmacy risks, dietary support, and advance care planning are critical in this group.
