Based on previous studies on development of heart failure with preserved ejection fraction (HFpEF), racial/ethnical background should be underscored when evaluating risk f actors for HFpEF incidence. As the ageing population increases sharply in China, HFpEF represents the dominant phenotype of all patients diagnosed with heart failure. In this cohort study, the investigators evaluated exposures or risk factors for HFpEF in Chinese Han patients with cardiovascular diseases (CVD). Our study may provide preventive and therapeutic targets for HFpEF in Chinese CVD patients.
To analyze factors contributing to the development and prognosis of heart failure with preserved ejection fraction.
