Incidence and predictors of early and late sudden cardiac death in hospitalized Japanese patients with new-onset systolic heart failure.

ABSTRACT:

Background

Patients with heart failure (HF) and low left ventricular ejection fraction (LVEF) are at high risk of sudden cardiac death (SCD). Optimal HF treatment can improve LVEF and reduce the risk of SCD. The aim of this study was to evaluate the incidence and predictors of SCD in Japanese patients with new-onset systolic HF and to investigate factors that affect LVEF improvement.

Methods

We retrospectively studied 174 consecutive hospitalized patients with new-onset HF and LVEF ≤35% (median age, 66 years; men, 71%). The primary outcome was a composite of SCD, sustained ventricular arrhythmias, and appropriate implantable cardioverter-defibrillator therapy.

Results

The cumulative rates of meeting of the primary outcome at 3, 12, and 36 months after discharge were 3
