Comparison of patients with peripartum heart failure and normal (≥55%) versus low (<45%) left ventricular ejection fractions.

The current definition of peripartum cardiomyopathy (PC) is restricted to patients with left ventricular systolic dysfunction (ejection fraction [EF]<45%). Data on peripartum heart failure (HF) with normal EF are sparse. We describe clinical characteristics of patients with normal (≥55%) and patients with low (<45%) left ventricular ejection fractions (LVEFs).
