Study Notes
Heart Failure (HF) Management
- Definition: Inability of the heart to pump enough blood to meet the body's oxygen and nutrient needs.
- Ejection Fraction (EF): Percentage of blood pumped out of ventricles during systole. Crucial in classifying HF types.
-
Types:
- Low EF (Systolic HF): Weakened ventricles struggle to pump effectively.
- Normal EF (Diastolic HF): Stiff ventricles fail to fill adequately during diastole.
- Left-sided HF: Primarily pulmonary symptoms (dyspnea, orthopnea) due to congested lungs.
- Right-sided HF: Primarily systemic symptoms (peripheral edema, JVD) due to fluid backup.
Etiology (Causes)
- Coronary artery disease (atherosclerosis)
- Systemic or pulmonary hypertension
- Valvular disorders (mitral stenosis or regurgitation)
- Diabetes mellitus
- Cardiomyopathy
Clinical Manifestations
- Left-sided HF: Dyspnea, orthopnea, pulmonary crackles, paroxysmal nocturnal dyspnea.
- Right-sided HF: JVD, peripheral edema, hepatomegaly, ascites.
Assessment and Diagnosis
- Comprehensive history and physical exam
- Echocardiography: Essential for EF measurement.
- Chest X-ray: Shows pulmonary congestion.
- BNP: Elevated levels indicate HF severity.
- Electrolytes, CBC, ECG: Supporting diagnostic evaluation.
Medical Management
- Goal: Improve cardiac function, reduce symptoms/hospitalizations, delay disease progression, and enhance quality of life.
-
Pharmacologic Therapy:
- ACE inhibitors (captopril): Vasodilation, diuresis
- ARBs (valsartan): Lower BP, improve cardiac output
- Beta-blockers: Slow heart rate, reduce workload
- Diuretics (furosemide): Increase urine output
- Digoxin: Improves contractility (caution for toxicity; therapeutic range 0.5–2.0 ng/mL)
- Anticoagulants: Prevent thromboembolism
- Avoid NSAIDs for this condition.
Lifestyle and Nutritional Modifications
- Low-sodium diet (≤2 g/day): Essential for reduced fluid retention.
- Restrict fluids, supplemental oxygen in cases of congestion.
- Avoid excess alcohol, smoking.
- Maintain a healthy weight and regular exercise.
Nursing Management
- Monitoring: Daily weights (monitor for excessive fluid gain), lung sounds, JVD, symptoms (orthopnea, dyspnea), skin turgor.
- Interventions: Medication administration, psychological support.
Nursing Diagnoses
- Activity intolerance
- Excess fluid volume
- Anxiety
- Noncompliance
Complications and Management
- Pulmonary Edema: Anxiety, restlessness, dyspnea, cyanosis, moist hands, distended neck veins. Immediate management includes supplemental oxygen, diuretics, and vasodilators.
- Thromboembolism: Prophylactic anticoagulation is crucial.
- Cardiac Arrest: Immediate CPR and advanced life support.
Diseases of the Heart Valves
- Mitral Regurgitation: Symptoms - Fatigue, dyspnea, palpitations. Management - ACE inhibitors, ARBs, surgery (valvuloplasty).
- Mitral Stenosis: Symptoms - Dyspnea, fatigue, orthopnea. Management - Anticoagulants, surgery (commissurotomy).
- Aortic Stenosis: Symptoms - Chest pain, syncope, exertional dyspnea. Management - Valve replacement or TAVI (transcatheter aortic valve implantation).
