Most Chinese cardiologists are challenged by the high mortality rate of heart failure (HF) in patients with reduced ejection fraction in China. This study was designed as a single-center, retrospective study. All consecutive HF patients with left ventricular ejection fraction (LVEF) ≤45% from January 1, 2007, to December 31, 2009, were enrolled. The primary outcome was all-cause mortality. The secondary outcome was all-cause mortality or the first cardiovascular readmission event. A total of 187 patients comprised the study population, classified into two groups: LVEF ≤35% (n=83) and LVEF 36% to 45% (n=104). The median follow-up was 18 months (2–41 months). All-cause mortality was 27% among patients with LVEF ≤35%, as compared with 14% among those with LVEF 36% to 45% ( P=.025). All-cause mortality or first cardiovascular readmission rates were 53% and 32% among patients with LVEF ≤35% and 36% to 45% (P=.003), respectively. The predictors of all-cause mortality were advanced age and New York Heart Association functional class, chronic kidney disease, oral β-blockers, and statins at discharge. The prognosis of chronic HF patients with LVEF ≤45% was poor in China, especially for patients with LVEF ≤35%. Cardiologists should provide further efforts to improve the prognosis of HF in Chinese patients. ©2011 Wiley Periodicals, Inc.
