Clinical characteristics of hospitalized heart failure patients with preserved, mid-range, and reduced ejection fractions in Japan.

Aims: There are regional differences in the patient characteristics, management, and outcomes of hospitalized patients with heart failure (HF). The aim of this study was to evaluate the clinical characteristics and outcomes of Japanese patients who are hospitalized with HF on the basis of the left ventricular ejection fraction (LVEF) stratum.

Methods And Results: We retrospectively conducted a multicentre cohort study of 1245 hospitalized patients with decompensated HF between 2013 and 2014.
