BACKGROUND: polymorphism has a prevalence of 30%-50% in Asian populations. In this study, we aimed to analyze risk factors contributing to the development of heart failure with preserved ejection fraction (HFpEF) along with the genetic exposure in Chinese patients hospitalized with cardiovascular diseases (CVD). METHODS: From July 2017 to October 2018, a total of 770 consecutive Chinese patients with normal left ventricular ejection fractions (LVEF) and established CVD (hypertension, coronary heart diseases, or diabetes) were enrolled in this prospective cross-sectional study. HFpEF was defined by the presence of at least one of symptom (dyspnoea and fatigue) or sign (rales and ankle swelling) related to heart failure; N-terminal pro-B-Type natriuretic peptide (NT pro-BNP ≥ 280 pg/mL); LVEF ≥ 50%; and at least one criterion related to elevated ventricular filling pressure or diastolic dysfunction (left atrial diameter > 40 mm, E/E' ≥ 13, E'/A' < 1 or concurrent atrial fibrillation). Logistic regression was performed to yield adjusted odds ratios (ORs) for HFpEF incidence associated with traditional and/or genetic exposures. RESULTS: < 0.001). CONCLUSIONS: variants, age and anaemia) were associated with an increased risk of HFpEF in Chinese CVD patients. Our results provide potential clues to the aetiology, pathophysiology and therapeutic targets of HFpEF.
Zhang et al. (Sun,) conducted a cross-sectional in Cardiovascular diseases (hypertension, coronary heart diseases, or diabetes) (n=770). Genetic variants, age, and anaemia was evaluated on Incidence of HFpEF (p=< 0.001). Genetic variants, age, and anaemia were associated with an increased risk of HFpEF in Chinese patients hospitalized with cardiovascular diseases (P < 0.001).
