Study Notes

Heart Failure Definition and Causes

Heart failure is a clinical condition where the heart cannot pump enough oxygenated blood to meet the body's needs.
Causes include structural abnormalities (e.g., valve malfunction, abnormal communication between heart chambers), inadequate myocardial contractility (e.g., cardiomyopathy, coronary artery disease), and cardiac arrhythmias.

Types of Heart Failure

Heart failure is categorized into right-sided and left-sided heart failure.

Right-Sided Heart Failure Signs and Symptoms

Distended neck veins with elevated pressure and congestion in systemic veins.
Peripheral edema (swelling) and weight gain.
Liver congestion and ascites (fluid buildup in the abdominal cavity).
Anorexia (loss of appetite) and nausea due to gastrointestinal tract swelling.
Nocturia (increased urination at night).

Left-Sided Heart Failure Signs and Symptoms

Paroxysmal nocturnal dyspnea (shortness of breath after sleeping).
Frequent coughing, particularly when lying down, and shortness of breath (orthopnea) due to pulmonary edema.
Fatigue and decreased exercise tolerance.
Pale, cold, clammy skin.
Dizziness or fainting.
Sudden death.

Treatment Options

Lifestyle changes (crucial for symptom management).
Medications (various types).
Surgery to correct heart or valve abnormalities.
Heart transplantation (a last resort).

Lifestyle Changes for Heart Failure

Dietary modifications: salt-restricted diet, reduced fat intake (especially animal fat), controlled fluid intake, weight management (caloric reduction), and frequent small meals instead of large ones.
Rest and exercise: individualized exercise programs after physician evaluation, alternating rest periods and activity, gradual increase in activity levels, and tailored exercises (e.g., walking, bicycling, swimming).
Smoking cessation and avoidance of alcohol.

Medications for Heart Failure

Diuretics: increase urination to remove excess salt and water, but electrolyte monitoring is vital.
Digitalis: strengthens the heart's pumping ability.
Vasodilators, ACE inhibitors, and calcium channel blockers: lower blood pressure to reduce strain on the heart.

Nursing Roles in Heart Failure Care

Positioning the patient comfortably.
Bed rest and bedside commode in acute stages.
Elevating the head of the bed.
Monitoring vital signs, daily weight, and administering medications.
Assessing respiratory distress and ABGs (arterial blood gases).
Providing pulmonary hygiene.
Administering supplemental oxygen as needed.
Encouraging deep breathing exercises.
Passive range-of-motion exercises.
Administering sedation as prescribed.
Restricting sodium.
Preventing constipation.
Monitoring patient compliance with medications, diet, and lifestyle changes.
Educating patients about their disease and treatment plan.
