Study Notes

Care of the Patient with Heart Failure

Heart failure (HF) is an abnormal condition involving impaired cardiac pumping and/or filling.
Ventricular function is impaired, leading to reduced exercise tolerance, decreased quality of life, and shortened lifespan.
Mortality risk is high.
Multiple risk factors contribute to heart failure.
Manifestations include both acute and chronic heart failure.

Preload and Afterload

Preload: The amount of blood in the ventricle before contraction (EDV - end diastolic volume).
Afterload: The pressure needed to open the heart valve, comparable to opening a door against resistance.
Stroke Volume: The volume of blood pumped out of the heart with each contraction; affected by preload, afterload, and contractility.
Cardiac Output: The amount of blood pumped by the heart per minute, dependent on heart rate, contractility, preload, and afterload.

Types of Heart Failure

Left-sided HF: Blood backs up into the left atrium and pulmonary veins, leading to increased pulmonary pressure and fluid buildup in the alveoli (pulmonary congestion). This causes symptoms like shortness of breath, cough, and fatigue.
Right-sided HF: Blood flows backward into the right atrium and venous circulation, resulting in peripheral edema, hepatomegaly, splenomegaly, and distention of the jugular veins. Symptoms include swelling, enlarged organs, and other symptoms.
Systolic HF: Left ventricle can't contract efficiently, indicating a pumping problem.
Diastolic HF: Left ventricle can't relax or fill adequately, causing a filling problem (often referred to as HF with preserved ejection fraction).

Clinical Manifestations

Left-sided HF: Hacking cough, worse at night, dyspnea, crackles/wheezes in lungs, frothy pink-tinged sputum, tachypnea, and shortness of breath.
Right-sided HF: Jugular vein distention, increased blood pressure (potentially), enlarged liver & spleen, anorexia, weight gain, dependent edema, polyuria at night, and swollen limbs.
Other symptoms include fatigue, weakness, shortness of breath (SOB), swelling of feet and legs, swollen/tender abdomen with loss of appetite, chronic lack of energy, difficulty sleeping at night due to breathing issues, cough with frothy sputum, and confusion/impaired memory.

Classification of Heart Failure

The classification is based on the tolerance to physical activity, graded from 1 to 4.
Class 1: No limitation of physical activity
Class 2: Slight limitation of activity
Class 3: Marked limitation of activity
Class 4: Inability to carry on any physical activity.

Heart Failure Cycle

The cycle is characterized by decreased cardiac output, activation of the sympathetic nervous system, resulting in decreased renal blood flow, and arterial and venous vasoconstriction. This leads to salt and water retention and remodeling of the heart (ventricular hypertrophy).

Heart Failure Complications

Pleural Effusion: Fluid buildup around the lungs.
Dysrhythmias (e.g., Atrial Fibrillation): Irregular heartbeats; can reduce cardiac output and increase the risk of stroke.
Hepatomegaly/Ascites: Enlarged liver and fluid buildup in the abdominal cavity.
Fibrosis/Cirrhosis: Scarring and damage of the liver.
Renal Insufficiency/Failure: Kidney problems due to decreased blood flow.
Cardiogenic Shock: Severe life-threatening condition.

Management of Acute Heart Failure (HF)

Goal: Improve left ventricular function by reducing intravascular volume, decreasing venous return, decreasing afterload, supporting gas exchange and oxygenation, and controlling anxiety.
Treatment: Diuretics (e.g., Lasix), ACE inhibitors, Beta-blockers, reduction of pulmonary congestion, patient positioning, improving gas exchange and oxygenation, and comfort measures.
Other treatments include drug treatment (diuretics, morphine, vasodilators, RAAS inhibitors, beta-blockers, anti-dysrhythmics), cardioversion, endotracheal intubation, mechanical ventilation, and circulatory assistive devices, fluid restriction, and symptom control.

Management of Chronic Heart Failure (HF)

Goal: Treat underlying causes and contributing factors, maximize cardiac output, improve myocardial contractility, manage symptoms, manage arrhythmias, hypertension, and CAD, provide physical and emotional rest, and promote self-management.

Nutritional Management of Chronic HF

Nutritional Therapy: Mild HF: 2g Na diet; severe HF: 1g Na diet.
Dietitian: Consultation is crucial.
Dietary Considerations: DASH diet, fluid restriction (1.5-2L/day), Daily weights, clothing, and reporting significant weight changes (3-5 lbs in 2 days or 3-5 lb in a week).
Report weight changes to health care provider.

Medical Management of Chronic HF

Drug Management: Diuretics to reduce sodium/fluid retention, ACE inhibitors to reduce afterload, Beta-blockers to improve contractility, inotropic drugs to improve contractility, and digoxin.
Additional Drugs: Phosphodiesterase inhibitors, corticosteroids, other inotropic agents, and other medications may be required depending on individual needs.

Nursing Interventions for Acute HF

Recognize primary characteristics of decreased cardiac output (fatigue, shortness of breath, swelling).
Place patient in appropriate positioning to optimize respiratory function (e.g., high-Fowler's position) to improve breathing and cardiac function.
Monitor pulse oximetry and administer oxygen as needed to improve tissue oxygenation.
Monitor vital signs to track cardiac and respiratory status.
Review lab results and hemodynamic monitoring to assess organ function and response to treatment.

Nursing Interventions for Acute HF (Continued)

Fluid restriction, accurate intake and output monitoring, and other supportive measures.
Relaxation and range-of-motion (ROM) exercises, compression stockings, and other interventions to promote comfort, prevent complications, and assist with self-management.
Serving small, frequent, sodium-restricted, and low-fat meals to minimize digestive strain.
Frequent rest periods alternating with activity are crucial to conserve energy and prevent cardiac stress.
Elevating legs when sitting to reduce edema and improve venous return.
Teaching self-management tools (daily weight, medication management, monitoring, and exercise plan modifications) are essential for long-term care and management of the condition.

Nursing Interventions for Chronic HF

Refer to cardiac rehabilitation programs for education and monitored exercise.
Facilitate weekly exercise (30-40 min, 3-5x per week) and resistance training, ensuring it aligns with individual limits to avoid overexertion, to slow progression of disease, and to support lifestyle changes.
Health teaching to help educate and assist patients in adapting to physiological and psychological changes.
Integrate the patient and family/support systems into overall care plan and teach lifestyle accommodations.
Emphasize energy-saving/efficient behaviors as crucial for long-term management.

Nursing Assessment:

Subjective: Patient's reports of symptoms (e.g., shortness of breath, swelling, fatigue).
Objective: Physical examination findings (e.g., edema, vital signs, respiratory status). This should include a comprehensive evaluation of all systems affected.
