A wide range of ejection fraction (EF) thresholds have been used to categorize patients with heart failure (HF) with "preserved" EF. Our goal was to characterize the clinical and echocardiographic differences among patients with cardiac structural/functional alterations and mid-range EF (mrEF) (EF 40-49%) compared to preserved EF (pEF) (EF ≥ 50%), irrespective of HF.
