Background: Epidemiological data for heart failure (HF) in the Chinese population is scarce. In this study, we described the clinical characteristics and outcomes of new-onset HF in our population.
Methods and results: We conducted a retrospective, observational study on consecutive Chinese patients hospitalized for new-onset HF between 2005 and 2012 in our center. A total of 1940 patients (mean age, 78.2 ± 11.8 years, 54.2% female) were identified. The rate of new HF hospitalization was 0.59 per 1000 population. The most prevalent comorbidities were hypertension (69.8%) and coronary artery disease (29.3%), and 52.3% had HF with preserved ejection fraction (HFpEF). The all-cause mortality was 19.5% at 1 year, 32.1% at 2 years, and 54% at 5 years. Cardiovascular mortality was 7.2% at 1 year, 11.8% at 2 years, and 20.7% at 5 years. No difference in all-cause mortality or cardiovascular mortality was observed between those with HF with reduced ejection fraction than HFpEF.
Conclusions: Our patients with new-onset HF shared similar clinical characteristics with the Caucasian population. The prognosis was poor with high all-cause mortality for both HFpEF and HF with reduced ejection fraction.
