Overview
Brief Summary
Obesity and heart failure with preserved ejection fraction (HFpEF) have multiple pathologic associations that affect the prognosis of HFpEF. Chinese people are more prone to visceral obesity, resulting in varying degrees of true obesity in individuals with the same body mass index (BMI). There are no prognostic studies of VFA/BMI in the HFpEF population.
Detailed Description
A total of 298 patients with HFpEF who were hospitalized in the Department of Cardiovascular Medicine of the First Affiliated Hospital of Chongqing Medical University from September 2020 to August 2023 were included in this prospective cohort study.All patients were followed up on November 30, 2023.The primary endpoint of the study was all-cause mortality and secondary endpoints were rehospitalization for heart failure and composite endpoints of both.After a median follow-up of 564 days, a total of 30 (10.1%) patients died and 82 (27.5%) were rehospitalized for heart failure. Patients with HFpEF were categorized into two groups according to median VFA/BMI (VFA/BMI \<5.49; VFA/BMI ≥5.49).The aim of this study was to elucidate whether VFA/BMI has prognostic value in patients with HFpEF by Kaplan-Meier survival analysis and cox regression analysis.
