Study Notes
Heart Failure (HF) Overview
- HF is a clinical syndrome marked by symptoms like breathlessness, ankle swelling, and fatigue, resulting from cardiac abnormalities.
- Common signs include elevated jugular venous pressure, pulmonary crackles, and peripheral edema.
Etiology and Types of Heart Failure
- Heart failure can occur due to:
- Structural or functional cardiac issues.
- Left ventricular ejection fraction (LVEF):
- HFrEF (Heart failure with reduced EF): LVEF < 40%.
- HFpEF (Heart failure with preserved EF): LVEF > 50%.
- Right ventricular dysfunction can also lead to heart failure, often secondary to left ventricular dysfunction-induced pulmonary hypertension.
Classification Based on Time Course
- Acute HF: Rapid onset symptoms.
- Chronic HF: Established diagnosis with gradual onset.
- Decompensated HF: Sudden or slow deterioration of chronic HF.
- Stable HF: Symptoms unchanged for at least one month.
- Congestive HF: Characterized by volume overload signs.
Diagnostic Investigations
- 12-lead ECG: Assesses heart rhythm, rate, QRS morphology, and other abnormalities.
- Chest X-ray: Identifies pulmonary congestion and excludes alternative diagnoses.
- Echocardiography: Evaluates myocardial structure and function for diagnosing HFrEF, HFmrEF, or HFpEF.
- Additional tests: Cardiac MRI, invasive coronary angiography, CT coronary angiography, cardiopulmonary exercise testing.
Management Strategies
- Treatment plans differ by type of HF:
- HFpEF: Focus on treating comorbidities and use of diuretics for congestion.
- HFmrEF: Similar approach as with HFpEF, consideration of ACE inhibitors, ARBs, beta-blockers, and MRAs.
- HFrEF: Pharmacological treatments are primary, often supplemented by devices and surgeries.
Pharmacological Treatment for HFrEF
- Core drugs include:
- ACE Inhibitors: First-line treatment shown to reduce mortality in HFrEF.
- Beta-blockers: Reduces mortality; initiated at low dosage and increased gradually.
- Mineralocorticoid Receptor Antagonists: Reduces mortality and HF hospitalizations; cautious in renal impairment.
- Angiotensin Receptor Neprilysin Inhibitor: Recommended for patients resistant to ACE or ARB therapy.
- SGLT2 Inhibitors: Reduces HF hospitalization and mortality; enhances diuresis.
Other Treatments for HFrEF
- Diuretics: Aim to maintain euvolemia; loop diuretics preferred for intense diuresis.
- ARBs: Alternative for patients intolerant to ACEi or ARNI.
- Ivabradine: Reduces HF hospitalization risk in eligible symptomatic patients.
- Combination Therapy: Hydralazine and isosorbide dinitrate for self-identified black patients with HFrEF.
- Digoxin: Considered if patients remain symptomatic despite other treatments.
Treatments Not Recommended for HFrEF
- Avoid thiazolidinediones, NSAIDs, non-dihydropyridine calcium channel blockers, and unnecessary ARB additions.
Device Treatment for HFrEF
- Implantable cardioverter-defibrillator (ICD): Recommended for patients recovering from life-threatening ventricular arrhythmias to reduce sudden death risk.
