This document discusses heart failure, including:
- Heart failure can be classified as HFrEF (ejection fraction ≤40%), HFmrEF (ejection fraction 41-49%), or HFpEF (ejection fraction ≥50%).
- Treatment for HFrEF focuses on ACE inhibitors, ARBs, beta-blockers, MRAs, and other drugs depending on symptoms.
- Prognosis is generally worse for HFrEF than HFpEF, with higher mortality rates. The NYHA classification also correlates with mortality risk.
- Optimal treatment can reduce 1-year mortality to 10-15% for NYHA I-II, 15-20% for NYHA III, and 20
