CORONARY ARTERY DISEASE Reporters; Dungog, Daniel Mark Menor, Nicole Dannielle  DEFINITION CAD is a condition characterized by the narrowing or blockage of the coronary arteries, usually due to atherosclerosis (buildup of plaque inside the artery walls). This reduces blood flow to the heart muscle, which can lead to chest pain (angina), heart attacks, or other heart complications. TYPES OF CORONARY ARTERY DISEASE There are three types of coronary artery disease: 1. Obstructive Coronary Artery Disease: This type occurs when a fatty substance called plaque builds up the coronary arteries, leading to artery narrowing. It’s the most common type of coronary heart disease. TYPES OF CORONARY ARTERY DISEASE 2. Nonobstructive Coronary Artery Disease: There’s no plaque buildup in the coronary arteries. Instead, narrowing in the coronary artery is caused by other conditions, including irregular constrictions (coronary vasospasm), heart tissue that compresses the coronary arteries ( myocardial bridging) or damage to the artery lining (endothelial dysfunction).  TYPES OF CORONARY ARTERY DISEASE 3. Spontaneous Coronary Artery Dissection (SCAD): A sudden tear in the coronary artery wall blocks blood flow to the heart. SCAD causes sudden symptoms that often present as a heart attack. SIGNS AND SYMPTOMS Chest pain (angina), fullness or pressure Fatigue Heart palpitations, or sensations of a racing heartbeat Shortness of breath (dyspnea) Swelling in the hands or feet PATHOPHYSIOLOGY Central Adiposiy Increased fasting blood glucose and productio of adipokines by adipose cells Metabolic Syndrome Insulin resistance Increased fasting blood glucose Dyslipidemia Hypertension Chronic inflammation Direct atherogenic effects ATHEROSCLEROSIS  Lifestyle Modifications: Patients are encouraged to adopt a heart- healthy lifestyle, including: MEDICAL MANAGEMENT Smoking cessation. Regular physical activity (at least 150 minutes of moderate-intensity exercise Risk Factor Control: per week). Management of underlying Healthy diet (low in saturated conditions such as fats, trans fats, cholesterol, hypertension, diabetes mellitus, and salt; high in fruits, and hyperlipidemia. vegetables, whole grains, and lean proteins). Weight management. PROCEDURES Electrocardiogram (ECG) A baseline test to detect ischemic changes, arrhythmias, previous myocardial infarctions, or ongoing ischemia. It records the electrical activity of the heart and may show ST- segment changes, T-wave inversions, or Q waves indicative of CAD. Echocardiography (Stress Echocardiogram) A baseline test to detect ischemic changes, arrhythmias, previous myocardial infarctions, or ongoing ischemia. It records the electrical activity of the heart and may show ST- segment changes, T-wave inversions, or Q waves indicative of CAD. Nuclear Stress Test (Myocardial Perfusion Imaging) Involves injecting a small amount of radioactive tracer (e.g., technetium-99m or thallium-201) and taking images of the heart at rest and after stress. The test assesses blood flow to the heart muscle and identifies areas of reduced perfusion, suggesting CAD. Coronary CT Angiography (CCTA) A non-invasive imaging technique using computed tomography (CT) to visualize the coronary arteries. CCTA provides detailed images of the coronary artery anatomy and can detect the presence of calcified and non-calcified plaques, stenosis, and anatomical anomalies Cardiac Magnetic Resonance Imaging (MRI) A non-invasive imaging method that provides detailed information about heart muscle viability, perfusion, and anatomy. Stress cardiac MRI can be used to evaluate myocardial ischemia and scarring. Coronary Angiography (Cardiac Catheterization) Considered the "gold standard" for diagnosing CAD. It involves the insertion of a catheter into the coronary arteries (usually via the radial or femoral artery), followed by the injection of contrast dye to visualize the arteries under X- ray. It provides direct visualization of coronary artery anatomy, the location and severity of stenosis, and other abnormalities. If significant stenosis is found, an intervention like percutaneous coronary intervention (PCI) with stenting may be performed during the same procedure. Intravascular Ultrasound (IVUS) An imaging modality used during coronary angiography to provide cross-sectional images of the coronary artery walls. It helps assess the degree and nature of atherosclerotic plaque and guide stent placement.  PHARMACOLOGICAL MANAGEMENT The pharmacologic treatment of CAD aims to reduce symptoms, prevent complications, and improve survival. Antiplatelet Agents: Aspirin (low-dose) is the cornerstone for preventing thrombosis. P2Y12 inhibitors (e.g., clopidogrel, ticagrelor) may be used in combination with or as an alternative to aspirin, especially in patients with stents or aspirin intolerance. Statins: To lower LDL cholesterol and stabilize atherosclerotic plaques (e.g., atorvastatin, rosuvastatin). Beta-blockers: To reduce heart rate, blood pressure, and myocardial oxygen demand (e.g., metoprolol, carvedilol). ACE Inhibitors/ARBs: For blood pressure control and to provide additional cardiovascular protection, especially in patients with diabetes or left ventricular dysfunction (e.g., enalapril, losartan). Calcium Channel Blockers: To reduce angina and control blood pressure, particularly when beta-blockers are contraindicated or not tolerated (e.g., amlodipine, diltiazem). Nitrates: For angina relief by dilating coronary arteries and veins (e.g., nitroglycerin, isosorbide mononitrate). Anticoagulants: In certain cases, like atrial fibrillation or recent myocardial infarction (e.g., warfarin, direct oral anticoagulants).  SURGICAL MANAGEMENT: Percutaneous Coronary Intervention (PCI): Angioplasty with stent placement is often performed in patients with significant coronary artery stenosis to restore blood flow. Drug-eluting stents (DES) are preferred to reduce the risk of restenosis. Coronary Artery Bypass Grafting (CABG): Indicated for patients with multi-vessel disease, left main coronary artery disease, or when PCI is not feasible. Involves bypassing the blocked coronary arteries using grafts from other vessels (e.g., internal mammary artery, saphenous vein).  LABORATORY MANAGEMENT Lipid Profile Total Cholesterol: Elevated levels are associated with an increased risk of CAD. Low-Density Lipoprotein (LDL) Cholesterol: Known as "bad cholesterol"; high levels contribute to plaque formation in arteries. High-Density Lipoprotein (HDL) Cholesterol: Known as "good cholesterol"; low levels are associated with an increased risk of CAD. Triglycerides: Elevated levels are an independent risk factor for CAD Cardiac Biomarkers Troponin (T and I): The most specific and sensitive biomarkers for myocardial injury. Elevated levels indicate myocardial infarction (MI) or acute coronary syndrome (ACS). Creatine Kinase-MB (CK-MB): An enzyme that increases in response to myocardial damage; less specific than troponin but still useful. Inflammatory Markers High-Sensitivity C-Reactive Protein (hs-CRP): A marker of inflammation that, when elevated, indicates an increased risk of CAD and future cardiovascular events. It is particularly useful for risk stratification in patients with intermediate risk. Erythrocyte Sedimentation Rate (ESR): A nonspecific marker of inflammation; it is not specific to CAD but may provide additional information in some cases.  LABORATORY MANAGEMENT Electrolytes and Renal Function Tests Serum Electrolytes (Sodium, Potassium, Calcium, Magnesium): Imbalances can predispose patients to arrhythmias, especially in those on diuretics or with heart failure. Complete Blood Count (CBC) To assess for anemia, which can exacerbate myocardial ischemia by decreasing oxygen- carrying capacity. To evaluate the white blood cell (WBC) count, which may be elevated in response to inflammation or infection, sometimes seen in acute coronary syndrome.  NURSING MANAGEMENT Assessment: Monitor vital signs, cardiac rhythm, oxygen saturation, and symptoms of angina. Assess for risk factors, medication adherence, and understanding of lifestyle modifications. Patient Education: Educate about CAD, medication regimen, lifestyle changes, and recognizing signs of complications (e.g., myocardial infarction). Provide instructions on proper use of medications (e.g., sublingual nitroglycerin for angina relief). Monitoring and Prevention: Monitor for potential side effects of medications (e.g., bleeding with antiplatelet agents, hypotension with beta-blockers). Encourage smoking cessation programs, dietary consultations, and physical activity as tolerated. Post-Intervention Care: For PCI: Monitor for signs of bleeding or hematoma at the catheter insertion site, and educate on activity restrictions. For CABG: Monitor for signs of infection, ensure proper wound care, pain management, and encourage deep breathing exercises. Rehabilitation: Encourage participation in cardiac rehabilitation programs for supervised exercise, risk factor modification, and psychological support.  HEART FAILURE  DEFINITION Heart failure is a condition in which the heart is unable to pump sufficient blood to meet the body’s needs. It can result from various heart conditions that weaken or damage the heart, including CAD, high blood pressure, and heart attacks.  TYPES OF HEART FAILURE LEFT-SIDED HEART FAILURE Systolic Heart Failure (HFrEF - Heart Failure with Reduced Ejection Fraction): The heart's left ventricle cannot contract effectively, reducing the amount of blood ejected with each beat. Common causes: Coronary artery disease, hypertension, or myocardial infarction. Diastolic Heart Failure (HFpEF - Heart Failure with Preserved Ejection Fraction): The heart muscle is stiff and cannot relax properly, limiting its ability to fill with blood during diastole. Common in older adults and those with hypertension, diabetes, or obesity. TYPES OF HEART FAILURE RIGHT-SIDED HEART FAILURE Often a result of left-sided heart failure, but it can also occur due to pulmonary hypertension or chronic lung disease. Causes a backup of blood in the veins, leading to swelling (edema) in the legs, ankles, or abdomen. TYPES OF HEART FAILURE CONGESTIVE HEART FAILURE A term used when heart failure causes fluid buildup (congestion) in the lungs and other body tissues. It can occur in both left-sided and right-sided heart failure. TYPES OF HEART FAILURE HIGH-OUTPUT HEART FAILURE This is a less common form of heart failure, where the heart pumps normally but the body's tissues demand more oxygen than the heart can supply. Causes can include severe anemia, hyperthyroidism, or arteriovenous malformations. SIGNS & SYMPTOMS Shortness of breath (Dyspnea) Fatigue and weakness Swelling (Edema) Rapid or irregular heartbeat (Palpitations) Persistent cough or wheezing Increased need to urinate, especially at night (Nocturia) Weight gain Reduced exercise tolerance Difficulty concentrating or confusion Lack of appetite or nausea  RISK FACTORS The risk for having HF increases with advancing age. For adults over 60 years of age, is more prevalent among men than women. Cigarette smoking Patient with major cardiovascular disease and disorders Obesity Poorly managed diabetes Metabolic syndrome PATHOPHYSIOLOGY MEDICAL MANAGEMENT Improvement of cardiac function with optimal pharmacologic management Reduction of symptoms and improvement of functional status Stabilization of patient condition and lowering of the risk of hospitalization. Delay of progression of HF and extension of life expectancy Promotion of lifestyle conducive to cardiac health LABORATORY PROCEDURES B-type Natriuretic Peptide (BNP) or N-terminal pro-BNP (NT-proBNP): these are key biomarkers in diagnosing and managing heart failure. Elevated levels suggest heart failure and indicate the severity of the condition. Complete Blood Count (CBC): to check for anemia or infection, both of which can exacerbate heart failure symptoms. Serum Electrolytes: measures sodium, potassium, and other electrolytes. Abnormal levels can result from heart failure treatments, particularly diuretics. Kidney Function Tests (Blood Urea Nitrogen [BUN], Creatinine): evaluates kidney function since heart failure and its treatment can affect kidney performance. Liver Function Tests: heart failure, particularly right-sided failure, can cause liver congestion, leading to liver dysfunction. LABORATORY PROCEDURES Thyroid Function Tests: hyperthyroidism or hypothyroidism can worsen heart failure, so thyroid-stimulating hormone (TSH) and other thyroid markers are checked. Lipid Profile: to assess cholesterol levels, as coronary artery disease is a common cause of heart failure. Blood Glucose or Hemoglobin A1c: to monitor for diabetes, which often coexists with heart failure. Arterial Blood Gas (ABG): especially in cases of acute heart failure, this test helps assess oxygenation and carbon dioxide levels in the blood. D-dimer Test: to rule out pulmonary embolism, which can present with similar symptoms to heart failure. DIAGNOSTIC PROCEDURES Echocardiogram (Echo): Most essential diagnostic tool for heart failure. Assesses heart structure, function, ejection fraction, and valve problems. Determines whether heart failure is systolic (HFrEF) or diastolic (HFpEF). Electrocardiogram (ECG or EKG): evaluates heart rhythm, detects arrhythmias, ischemia (lack of oxygen to the heart), or previous heart attacks that may contribute to heart failure. Chest X-ray: helps identify the size and shape of the heart and the presence of fluid in the lungs, which is a sign of heart failure. Cardiac MRI (Magnetic Resonance Imaging): Provides detailed images of the heart’s structure and function. Useful for assessing myocarditis, amyloidosis, or scarring from previous heart attacks. Cardiac Catheterization (Angiography): To check for blocked coronary arteries, which can cause heart failure. A catheter is inserted into the heart, and dye is injected to visualize the coronary arteries on X-ray. DIAGNOSTIC PROCEDURES Stress Test (Exercise or Pharmacologic): Evaluates the heart's ability to respond to stress, either through exercise or medication that mimics exercise. Helps assess the severity of heart failure and the presence of ischemia. Nuclear Imaging (e.g., SPECT or PET): Shows areas of the heart with poor blood flow or damage. Often used when other imaging techniques are inconclusive. Right Heart Catheterization: Measures pressures in the heart chambers and pulmonary arteries to assess the severity of heart failure and the degree of pulmonary hypertension. Coronary Computed Tomography Angiography (CTA): Non-invasive imaging to visualize the coronary arteries and detect blockages that may contribute to heart failure. DIAGNOSTIC PROCEDURES Sleep studies: to rule out sleep apnea, a common condition in patients with heart failure. Genetic testing: this may be considered for familial cardiomyopathies. These two tests will depend on the case of the patient, to help determine the cause, type and severity of heart failure, allowing for appropriate treatment plans to be made. PHARMACOLOGICAL MANAGEMENT Angiotensin-Converting Enzyme (ACE) Inhibitors - Lisinopril, Enalapril, Ramipril, Captopril to reduce mortality, improve symptoms, and slow the progression of heart failure. Angiotensin II Receptor Blockers (ARBs) - Losartan, Valsartan, Candesartan often used as an alternative in patients who cannot tolerate ACE inhibitors due to side effects like coughing. Angiotensin Receptor-Neprilysin Inhibitors (ARNIs) - Sacubitril/Valsartan (Entresto) more effective than ACE inhibitors or ARBs alone in reducing mortality and hospitalizations in patients with systolic heart failure (HFrEF). Beta-Blockers - Carvedilol, Metoprolol Succinate (extended-release), Bisoprolol to improve symptoms, reduce hospitalizations, and improve survival. PHARMACOLOGICAL MANAGEMENT Diuretics Loop Diuretics: Furosemide, Torsemide, Bumetanide Thiazide Diuretics: Hydrochlorothiazide Potassium-Sparing Diuretics: Spironolactone, Eplerenone to relieve symptoms of fluid overload (edema, shortness of breath). Potassium-sparing diuretics like Spironolactone also help reduce mortality in heart failure with reduced ejection fraction (HFrEF). Aldosterone Antagonists (Mineralocorticoid Receptor Antagonists) - Spironolactone, Eplerenone Mechanism: Block the effects of aldosterone, reducing fluid retention, sodium reabsorption, and potassium loss. Purpose: Reduce morbidity and mortality, especially in patients with HFrEF. Hydralazine and Nitrates - Hydralazine (vasodilator) & Isosorbide dinitrate or Isosorbide mononitrate (nitrate) this combination is particularly beneficial in African American patients with heart failure and for those who cannot tolerate ACE inhibitors or ARBs. It reduces hospitalizations and improves survival. Digoxin (Cardiac Glycosides) this is used to relieve symptoms and improve exercise capacity, especially in patients with atrial fibrillation or symptoms that persist despite standard therapy. PHARMACOLOGICAL MANAGEMENT Sodium-Glucose Co-Transporter 2 (SGLT2) Inhibitors - Dapagliflozin, Empagliflozin to reduce hospitalizations and mortality in patients with heart failure with reduced ejection fraction (HFrEF) and are beneficial in heart failure with preserved ejection fraction (HFpEF). Ivabradine to use in patients with HFrEF who remain symptomatic despite being on maximum tolerated doses of beta-blockers or who cannot tolerate beta-blockers. Reduces hospitalizations for heart failure. Anticoagulants - Warfarin, Apixaban, Rivaroxaban to use in patients with heart failure who are at risk of blood clots. Statins (HMG-CoA Reductase Inhibitors) - Atorvastatin, Rosuvastatin to indicate in patients with heart failure caused by coronary artery disease.  SURGICAL MANAGEMENT Coronary Artery Bypass Grafting (CABG): to improve blood flow to the heart by bypassing blocked coronary arteries. Indication for patients with heart failure caused by coronary artery disease (ischemic heart failure) or those who have had heart attacks. CABG can improve heart function by restoring blood flow to areas of the heart affected by blockages. Outcome: Can reduce symptoms of heart failure, improve survival, and reduce the risk of future heart attacks. Heart Valve Repair or Replacement: it corrects malfunctioning heart valves (e.g., mitral valve, aortic valve) that can cause or worsen heart failure by affecting the flow of blood through the heart. Indication for heart failure caused by valvular heart disease, such as mitral valve regurgitation or aortic stenosis. Techniques: Valve repair: Reshapes or strengthens the valve to restore normal function. Valve replacement: Replaces the damaged valve with a mechanical or biological prosthesis. Outcome: Alleviates symptoms, prevents worsening of heart failure, and improves survival. Implantable Cardioverter-Defibrillator (ICD) - to prevent sudden cardiac death by monitoring the heart rhythm and delivering an electric shock to restore normal rhythm if a life-threatening arrhythmia occurs. Indication for patients with heart failure at risk for sudden cardiac death due to ventricular arrhythmias, particularly those with an ejection fraction of ≤35%. Outcome: Reduces the risk of sudden death but does not directly improve heart failure symptoms.  SURGICAL MANAGEMENT Cardiac Resynchronization Therapy (CRT) - it uses a specialized pacemaker to coordinate the contractions of the heart’s ventricles, improving the efficiency of the heart's pumping. Indication for patients with heart failure and electrical conduction delays (e.g., left bundle branch block) leading to inefficient heart function. Outcome: Improves heart function, reduces symptoms, and lowers the risk of hospitalization and death. Ventricular Assist Devices (VADs) - mechanical pumps that help the heart pump blood throughout the body. These devices can be used temporarily or as long-term therapy. Indication for severe heart failure (end-stage heart failure) where the heart is no longer able to pump blood effectively. VADs can be used as: Bridge to transplant: Temporarily supports patients while they wait for a heart transplant. Destination therapy: Permanent solution for patients who are not candidates for heart transplant. Outcome: Improves survival and quality of life in patients with severe heart failure. Heart Transplantation - it replaces the patient’s diseased heart with a healthy donor heart. Indication: end-stage heart failure that does not respond to medical or other surgical treatments, and when the patient is a suitable candidate for transplantation. Outcome: Offers the best chance for long-term survival in patients with severe, refractory heart failure.  SURGICAL MANAGEMENT Transcatheter Aortic Valve Replacement (TAVR) - minimally invasive procedure to replace a narrowed aortic valve that fails to open properly (aortic stenosis), which can contribute to heart failure. Indication: Older or high-risk patients with heart failure due to aortic stenosis who are not candidates for traditional open-heart surgery. Outcome: Improves symptoms and can improve survival in high-risk patients. Left Ventricular Reconstruction (Surgical Ventricular Restoration) - reshapes and reduces the size of the left ventricle to improve heart function. Indication: Patients with heart failure due to left ventricular enlargement following a heart attack or chronic ischemic heart disease. Outcome: Improves heart function, reduces symptoms, and can improve quality of life. Pericardiectomy - surgical removal of part or all of the pericardium (the sac surrounding the heart). Indication: Heart failure caused by constrictive pericarditis, where the pericardium becomes thickened and restricts the heart's ability to pump blood effectively. Outcome: Relieves pressure on the heart and improves heart function.  SURGICAL MANAGEMENT MitraClip (Transcatheter Mitral Valve Repair) - minimally invasive procedure to clip the leaflets of the mitral valve together, reducing mitral regurgitation (leakage of the mitral valve). Indication for patients with heart failure who have significant mitral regurgitation and are not candidates for open-heart surgery. Outcome: Reduces symptoms and improves quality of life in patients with mitral regurgitation.  LABORATORY MANAGEMENT B-Type Natriuretic Peptide (BNP) / N-Terminal proBNP (NT-proBNP): are proteins released by the heart in response to increased pressure and volume overload. These levels rise as heart failure worsens and fall as it improves. Electrolytes: can indicate kidney dysfunction, fluid overload, or complications related to medications. Renal Function Tests: to assess kidney function, which is closely related to heart function. Heart failure can reduce blood flow to the kidneys, leading to renal impairment. Complete Blood Count (CBC): assesses overall health and detects conditions like anemia, infection, or inflammation that can worsen heart failure symptoms. Liver Function Tests: heart failure can lead to congestion in the liver (hepatic congestion), resulting in elevated liver enzymes. This is particularly seen in right-sided heart failure. Thyroid Function Tests: thyroid dysfunction (both hyperthyroidism and hypothyroidism) can contribute to heart failure or worsen existing heart failure. Screening for thyroid dysfunction is important, particularly in new-onset heart failure.  LABORATORY MANAGEMENT Fasting Lipid Profile: high cholesterol levels, particularly elevated LDL, contribute to atherosclerosis and coronary artery disease, which are major causes of heart failure. Blood Glucose and Hemoglobin A1c (HbA1c): diabetes is a major risk factor for heart failure, and uncontrolled blood sugar can worsen heart function. HbA1c provides a long-term measure of blood sugar control. Arterial Blood Gas (ABG): assess oxygenation and acid-base balance in patients with severe heart failure or those experiencing respiratory distress. Cardiac Enzymes (Troponins): used to assess for myocardial injury (heart attack) in patients with acute heart failure exacerbations. Elevated levels suggest myocardial ischemia or infarction.  LABORATORY MANAGEMENT C-Reactive Protein (CRP) and High-Sensitivity CRP (hs-CRP): a marker of inflammation, CRP levels are often elevated in heart failure, especially during episodes of decompensation. High-sensitivity CRP (hs-CRP) is more specific for cardiovascular risk assessment. Serum Osmolality: it helps assess fluid balance and detect abnormalities such as dilutional hyponatremia, common in heart failure patients with excess fluid retention. Lactate: elevated lactate levels indicate tissue hypoxia and can be a marker of severe heart failure or shock.  LABORATORY MANAGEMENT Urinalysis: detects proteinuria, which can indicate kidney dysfunction, and assesses for other abnormalities such as infection. Genetic Testing (depends on the case): to identify underlying genetic mutations in cases of familial cardiomyopathy or inherited heart conditions leading to heart failure. NURSING MANAGEMENT Assessment: vital signs, lung and heart sounds, weight monitoring, and lab values. Medication Management: administer diuretics, ACE inhibitors, beta-blockers, and digoxin. Oxygenation: maintain optimal oxygen levels and reduce pulmonary congestion. Fluid Management: enforce fluid and sodium restrictions, monitor intake and output. Complication Monitoring: watch for signs of pulmonary edema, arrhythmias, and thromboembolism. Patient Education: teach about medications, diet, weight monitoring, and symptom recognition. Emotional and Psychosocial Support: help manage emotional distress, involve family, and discuss advanced care planning.  CONGESTIVE HEART FAILURE  DEFINITION Congestive Heart Failure (CHF) is a chronic condition where the heart's ability to pump blood effectively is weakened, causing a buildup of fluid (congestion) in the lungs, liver, abdomen, and lower extremities. This results in symptoms such as shortness of breath, fatigue, swelling in the legs, and fluid retention. CHF can be caused by conditions that damage the heart, such as coronary artery disease, high blood pressure, or previous heart attacks. It can affect either the left side, right side, or both sides of the heart. SIGNS & SYMPTOMS Shortness of breath (dyspnea) Fatigue and weakness Swelling (edema) Rapid or irregular heartbeat (palpitations) Persistent cough or wheezing Sudden weight gain Decreased ability to exercise Increased need to urinate at night (Nocturia) Swollen Abdomen Reduced appetite and Nausea Confusion Chest Pain PATHOPHYSIOLOGY  MEDICAL MANAGEMENT The primary goals of medical management are to reduce symptoms, improve quality of life, and prevent disease progression or complications. Lifestyle modifications: Diet: Low-sodium diet to reduce fluid retention, limited fluid intake, and weight management. Physical activity: Appropriate exercise programs to strengthen the heart. Smoking cessation and alcohol limitation. Daily weight monitoring to detect fluid retention early. Treat underlying causes: Treatment of conditions like hypertension, coronary artery disease, diabetes, or arrhythmias, which may contribute to heart failure.  MEDICAL MANAGEMENT Electrocardiogram (ECG/EKG) - Measures the electrical activity of the heart. - Detects arrhythmias, heart attack, or other abnormalities such as left ventricular hypertrophy (thickening of the heart muscle). Chest X-ray - Provides an image of the heart and lungs. - Helps detect: Heart enlargement. Fluid in the lungs (pulmonary edema). Other lung issues that could contribute to symptoms. Echocardiogram (ECHO) - Key diagnostic tool for CHF. - Uses ultrasound to create detailed images of the heart’s structure and function. - Measures ejection fraction (EF), which indicates how well the heart is pumping. An EF below 40% suggests heart failure with reduced ejection fraction (HFrEF). - Assesses heart valves and detects any structural abnormalities (e.g., valve disease, wall motion abnormalities).  MEDICAL MANAGEMENT Holter Monitor - A portable device worn for 24 to 48 hours to continuously monitor heart activity, helping to detect intermittent arrhythmias that might not be seen in a standard ECG. Right Heart Catheterization - A catheter is inserted into a vein and guided to the right side of the heart to measure pressures in the heart chambers and pulmonary arteries. - Helps in assessing the severity of CHF and pulmonary hypertension  PHARMACOLOGICAL MANAGEMENT Medications are central to managing CHF, aiming to improve symptoms and slow progression of the disease. Diuretics (e.g., furosemide, spironolactone): Help reduce fluid retention by promoting urination. ACE inhibitors (e.g., enalapril, lisinopril): Help relax blood vessels, reduce blood pressure, and decrease the workload on the heart. Angiotensin II receptor blockers (ARBs, e.g., losartan, valsartan): An alternative to ACE inhibitors to reduce blood pressure. Beta-blockers (e.g., carvedilol, metoprolol): Slow heart rate and reduce blood pressure, improving heart function.  PHARMACOLOGICAL MANAGEMENT Aldosterone antagonists (e.g., spironolactone, eplerenone): Reduce fluid retention and help prevent worsening of heart failure. Digoxin: Increases the strength of heart contractions and slows heart rate, useful in some cases of heart failure with atrial fibrillation. SGLT2 inhibitors (e.g., empagliflozin, dapagliflozin): Originally for diabetes, these drugs help reduce hospitalizations in heart failure patients. Vasodilators (e.g., hydralazine and nitrates): Lower blood pressure and reduce the heart’s workload. Ivabradine: Can reduce heart rate in patients with chronic heart failure.  SURGICAL MANAGEMENT Surgery may be considered when medications and lifestyle changes are insufficient, or in cases where a structural problem contributes to heart failure. Coronary artery bypass grafting (CABG): For patients with heart failure caused by coronary artery disease, this surgery improves blood flow to the heart. Heart valve repair or replacement: In cases where damaged valves contribute to CHF. Implantable devices: Implantable cardioverter-defibrillator (ICD): Prevents life-threatening arrhythmias by shocking the heart if abnormal rhythms are detected. Cardiac resynchronization therapy (CRT): A specialized pacemaker that coordinates heart contractions in patients with severe heart failure.  SURGICAL MANAGEMENT Left ventricular assist device (LVAD): A mechanical pump for patients with severe heart failure, often as a bridge to heart transplantation. Heart transplantation: Considered for end-stage heart failure when other treatments have failed.  LABORATORY MANAGEMENT Regular laboratory tests are important in the diagnosis and ongoing management of CHF to monitor heart function, electrolyte balance, and medication effects. B-type natriuretic peptide (BNP) or N-terminal pro-BNP (NT- proBNP): Elevated levels suggest heart failure and help gauge the severity of the condition. Electrolytes (e.g., sodium, potassium, chloride): Monitoring is essential due to the effects of diuretics and heart medications, which can cause imbalances.  LABORATORY MANAGEMENT Renal function tests (creatinine, blood urea nitrogen – BUN): CHF and its treatments can affect kidney function, so monitoring is necessary. Liver function tests: To assess any impact of CHF on the liver, especially in severe cases with liver congestion. Complete blood count (CBC): To detect anemia or infection, which can worsen heart failure.  LABORATORY MANAGEMENT Thyroid function tests: Hypothyroidism or hyperthyroidism can contribute to heart failure. Lipid profile: To assess cholesterol levels, especially in patients with coronary artery disease. Blood glucose and HbA1c: To monitor for diabetes or assess its control, as diabetes can worsen heart failure. Cardiac enzymes (e.g., troponin): Used during acute events, such as heart attacks, to assess heart damage. NURSING MANAGEMENT Nurses play a crucial role in monitoring, educating, and caring for patients with CHF. Patient education: Teaching patients about medication adherence, dietary restrictions (low sodium, fluid management), and daily weight monitoring. Monitoring for signs of fluid overload: Regular assessment of weight, respiratory status, heart sounds, and peripheral edema. Medication management: Administering medications and monitoring for side effects (e.g., hypotension, electrolyte imbalances). Emotional and psychosocial support: Helping patients cope with the chronic nature of heart failure. NURSING MANAGEMENT Care coordination: Collaborating with physicians, dietitians, physical therapists, and other healthcare providers to ensure comprehensive care. Preventing complications: Including monitoring for skin breakdown (due to edema), infection, and promoting mobility. Managing devices: Care and education on pacemakers, ICDs, or LVADs if applicable.
