Management Approach for Heart Failure According to Kumar and Clark's Clinical Medicine

The management of heart failure requires a structured approach that includes establishing the diagnosis, determining etiology, assessing severity, and implementing appropriate pharmacological and non-pharmacological interventions to reduce mortality and improve quality of life.

Diagnostic and Initial Assessment

• Establish that the patient has heart failure through clinical evaluation, natriuretic peptide testing, and echocardiography 1
• Assess presenting features including pulmonary edema, exertional breathlessness, fatigue, and peripheral edema 1
• Determine the etiology of heart failure (ischemic, hypertensive, valvular, etc.) 1
• Identify precipitating and exacerbating factors 1
• Evaluate concomitant diseases relevant to heart failure management 1, 2
• Classify heart failure as reduced ejection fraction (HFrEF, EF ≤40%) or preserved ejection fraction (HFpEF, EF ≥50%) 1, 2
• Assess severity using New York Heart Association (NYHA) functional classification 2

Pharmacological Management

For Heart Failure with Reduced Ejection Fraction (HFrEF)

• ACE inhibitors should be used as first-line therapy in patients with reduced left ventricular systolic function to improve survival and reduce hospitalizations 1
• Beta-blockers should be added to ACE inhibitors in stable patients to reduce mortality 1, 2
• Diuretics are essential for symptomatic treatment when fluid overload is present (pulmonary congestion or peripheral edema) 1
• Mineralocorticoid receptor antagonists (spironolactone) should be considered in patients with NYHA class III-IV symptoms despite optimal therapy, with careful monitoring of potassium and renal function 1, 3
• Consider angiotensin receptor blockers (ARBs) in patients intolerant to ACE inhibitors 1
• Digoxin may be added to improve clinical status in patients with persistent symptoms despite ACE inhibitors and diuretics 1
• SGLT2 inhibitors should be used in patients with type 2 diabetes and established cardiovascular disease to prevent heart failure hospitalizations 1
• Ivabradine may be considered in patients with heart rate ≥70 bpm despite maximally tolerated beta-blocker therapy 4

For Heart Failure with Preserved Ejection Fraction (HFpEF)

• Focus on managing comorbid conditions such as hypertension, ischemic heart disease, and diabetes 1
• Control blood pressure according to guidelines 1
• Diuretics for symptom relief when fluid overload is present 1

Non-Pharmacological Management

• Provide patient education about heart failure, including symptom recognition and self-management 1, 2
• Encourage self-weighing and reporting weight gains of >2 kg in 3 days 1, 2
• Promote regular physical activity and exercise training in stable patients 1, 2
• Implement moderate sodium restriction in symptomatic patients 1, 2
• Advise on fluid intake, alcohol consumption, and smoking cessation 1, 2

Multidisciplinary Approach and Follow-up

• Implement care through a multidisciplinary heart failure team 1, 2, 5
• Disease management programs should be considered for high-risk patients to reduce hospitalizations and mortality 1, 2, 5
• Schedule regular follow-up visits to monitor clinical status, medication adherence, and treatment response 1, 2
• Monitor biomedical parameters including renal function, electrolytes, and natriuretic peptides 1, 2
• Early follow-up (within 7-14 days) after hospital discharge 2, 6

Advanced Heart Failure Management

• Consider cardiac resynchronization therapy (CRT) and implantable cardioverter-defibrillators (ICDs) in appropriate patients 1
• Evaluate for mechanical circulatory support or heart transplantation in end-stage heart failure 7
• Consider palliative care approaches for patients with advanced heart failure 1, 6

Common Pitfalls to Avoid

• Inadequate diuresis in volume-overloaded patients 2
• Failure to uptitrate medications to target doses 1, 2
• Neglecting patient education and self-care strategies 2, 8
• Inadequate transitional care planning leading to early readmissions 2, 9
• Excessive potassium supplementation in patients receiving spironolactone 3
