Why the study?
Evidence regarding outcomes across HFpEF, HFmrEF, and HFrEF is incomplete and inconsistent, with limited data on their proportions and long-term prognosis in China.
Population
4880 hospitalized HF patients undergoing coronary angiography in southern China
Comparison
HFpEF vs HFmrEF vs HFrEF
Design
Registry-based cohort study
Follow-up
5 year

In a Chinese cohort of hospitalized heart failure patients, lower ejection fraction was independently associated with a stepwise increase in 5-year all-cause mortality, with HFrEF carrying nearly twice the mortality risk of HFpEF.
