Heart failure with reduced ejection fraction

Last edited: 4/16/2026

Overview

Heart failure with reduced ejection fraction (HFrEF) is a clinical syndrome characterized by the inability of the heart to pump sufficient blood to meet metabolic demands, typically defined by left ventricular ejection fraction (LVEF) ≤40%, leading to symptoms such as dyspnea, fatigue, and fluid retention 1.

Diagnosis

  • Key Diagnostic Criteria: Symptoms of dyspnea, fatigue, and edema; objective evidence of LVEF ≤40% via echocardiography 1.
  • Recommended Tests: Echocardiography for LVEF measurement, B-type natriuretic peptide (BNP) or N-terminal pro-BNP (NT-proBNP) levels 1.
  • Grading: NYHA/KCCLS functional class, severity assessed by clinical symptoms and objective measures 1.

    • Management

  • First-Line Treatments: Angiotensin-converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARBs) (e.g., ramipril 10 mg daily, losartan 12.5 mg daily) 1.
  • Adjunctive Treatments: Beta-blockers (e.g., carvedilol 6.25 mg twice daily, metoprolol succinate 25 mg daily), mineralocorticoid receptor antagonists (e.g., spironolactone 25 mg daily) 1.
  • Lifestyle Modifications: Structured exercise programs, dietary sodium restriction 1.
  • Cardiac Rehabilitation: Home-based programs associated with fewer hospitalizations compared to center-based programs 1.

    • Special Populations

  • Elderly: Home-based cardiac rehabilitation may be particularly beneficial for reducing hospitalizations in medically complex elderly patients 1.

    • Key Recommendations

  • Implement home-based cardiac rehabilitation programs to reduce hospitalization rates in HFrEF patients (Evidence: Strong) 1.
  • Initiate ACE inhibitors or ARBs as first-line pharmacotherapy to improve outcomes in HFrEF (Evidence: Strong) 1.
  • Incorporate beta-blockers into treatment regimens to enhance survival and reduce hospitalizations (Evidence: Strong) 1.
