What is the comprehensive management of heart failure?

Comprehensive Management of Heart Failure

The comprehensive management of heart failure centers on ACE inhibitors as first-line pharmacological therapy combined with diuretics for symptomatic relief, beta-blockers for survival benefit, and structured patient education with lifestyle modifications—all aimed at preventing disease progression, improving quality of life, and reducing mortality. 1, 2

Treatment Goals

The primary objectives are prevention and control of diseases leading to cardiac dysfunction, maintenance or improvement in quality of life, and improved survival. 1

Pharmacological Management

First-Line Therapy

• ACE inhibitors are the cornerstone of treatment for patients with reduced left ventricular systolic function (ejection fraction ≤40%). 1, 2
• Start with a low dose and titrate to recommended maintenance dosages proven effective in large trials. 1
• Check blood pressure, renal function, and electrolytes 1-2 weeks after each dose increment, at 3 months, and subsequently at 6-month intervals. 1

Critical initiation protocol for ACE inhibitors: 1

1. Review and reduce diuretic doses 24 hours before starting
2. Avoid excessive diuresis before treatment
3. Consider evening dosing when supine to minimize hypotensive effects
4. Stop treatment if renal function deteriorates substantially
5. Avoid potassium-sparing diuretics during initiation
6. Strictly avoid NSAIDs

Diuretics for Symptom Control

• Loop diuretics or thiazides are essential when fluid overload manifests as pulmonary congestion or peripheral edema, providing rapid improvement in dyspnea and exercise tolerance. 1, 2
• Always administer in combination with ACE inhibitors. 1
• If GFR <30 ml/min, avoid thiazides except when prescribed synergistically with loop diuretics. 1
• For insufficient response: increase diuretic dose, combine loop diuretics with thiazides, or administer loop diuretics twice daily. 1
• In severe chronic heart failure, add metolazone with frequent measurement of creatinine and electrolytes. 1

Beta-Blockers

• Beta-blockers improve survival and reduce hospitalizations in patients with heart failure with reduced ejection fraction (HFrEF). 2, 3, 4
• These are now standard therapy alongside ACE inhibitors and diuretics. 3, 4

Additional Pharmacological Options

• Angiotensin receptor blockers (ARBs) are recommended if ACE inhibitors are not tolerated. 3, 4
• Aldosterone antagonists may be added in select patients with stable NYHA class III or IV heart failure. 3, 4
• SGLT2 inhibitors are now first-line for HF with mildly reduced or preserved ejection fraction. 5
• Sacubitril/valsartan (angiotensin receptor-neprilysin inhibitor) reduces cardiovascular death and hospitalization in chronic heart failure with reduced ejection fraction. 6, 5
• Digoxin improves clinical symptoms, especially in patients with atrial fibrillation. 3
• Hydralazine and isosorbide dinitrate are alternatives when ACE inhibitors/ARBs cannot be used. 3, 4

Potassium-Sparing Diuretics

• Use only if hypokalemia persists after initiation of ACE inhibitors and diuretics. 1
• Start with 1-week low-dose administration, check serum potassium and creatinine after 5-7 days, and recheck every 5-7 days until potassium values stabilize. 1

Non-Pharmacological Management

Patient Education (Critical Component)

Provide specific education on: 1, 2

• What heart failure is and why symptoms occur
• Causes of heart failure and how to recognize worsening symptoms
• What to do when symptoms occur
• Daily self-weighing (report weight gains >2 kg in 3 days)
• Rationale of treatments and importance of medication adherence
• Smoking cessation (use nicotine replacement therapies)
• Prognosis and disease trajectory

Exercise and Activity

• Rest is NOT encouraged in stable conditions—daily physical and leisure activities prevent muscle deconditioning. 1, 2
• Exercise training programs are recommended for stable NYHA class II-III patients. 1, 2
• Sexual activity should be maintained as tolerated. 1

Dietary and Social Modifications

• Control sodium intake, particularly in patients with severe heart failure. 1, 2
• Avoid excessive fluid intake only in severe HF. 1, 2
• Avoid excessive alcohol consumption. 1, 2
• Advise on potential problems with long flights, high altitudes, hot humid climates when using diuretics/vasodilators. 1

Monitoring and Follow-Up

• Monitor symptoms, weight fluctuations, and medication adherence daily. 2
• Schedule early follow-up within 7 days of hospital discharge. 2
• Refer high-risk patients to multidisciplinary heart failure disease management programs. 2
• Reassess after therapy initiation to evaluate symptoms, health status, and left ventricular function. 5

Management of Comorbidities

Treatment of comorbidities such as diabetes mellitus, ischemic heart disease, and atrial fibrillation is crucial through each stage of heart failure. 5, 7

Medications to Avoid

Strictly avoid or use with extreme caution: 8, 9

• NSAIDs and COX-2 inhibitors
• Class I antiarrhythmic agents
• Calcium antagonists
• Tricyclic antidepressants
• Corticosteroids
• Combination of ACE inhibitors, ARBs, and mineralocorticoid receptor antagonists

Common Pitfalls

• Inadequate diuresis in volume-overloaded patients leads to persistent symptoms. 2
• Failure to uptitrate medications to target doses reduces survival benefit. 2
• Neglecting patient education and self-care strategies increases readmission rates. 2
• Inadequate transitional care planning results in early hospital readmissions. 2

Special Considerations for Right Heart Failure

Right heart failure requires fundamentally different management: 8, 9

• Identify underlying etiology immediately (pulmonary hypertension, RV infarction, pulmonary embolism)
• Use diuretics and vasodilators cautiously to avoid compromising RV filling pressure
• For RV infarction: perform urgent coronary angiography and volume loading with normal saline (500-ml bolus, then 500 ml/h) unless left heart volume overload present
• For pulmonary hypertension-related RHF: pulmonary vasodilators (phosphodiesterase-5 inhibitors, endothelin antagonists, prostacyclin analogues) are cornerstone therapy
• Consider inotropic support (dobutamine 2.5-5.0 μg/kg/min or milrinone 0.25-0.75 μg/kg/min)
• Maintain oxygen saturation above 90% at all times
