Table 4. Classification of HF by LVEF
Type of HF According
to LVEF Criteria
HFrEF
(HF with reduced EF)
• LVEF ≤40%
HFimpEF
(HF with improved EF)
• Previous LVEF ≤40% and a follow-up measurement of
LVEF >40%
HFmrEF
(HF with mildly
reduced EF)
• LVEF 41%–49%
• Evidence of spontaneous or provokable increased LV
filling pressures (e.g., elevated natriuretic peptide,
noninvasive and invasive hemodynamic measurement)
HFpEF
(HF with preserved EF)
• LVEF ≥50%
• Evidence of spontaneous or provokable increased LV
filling pressures (e.g., elevated natriuretic peptide,
noninvasive and invasive hemodynamic measurement)
