简要总结
Study of the prognosis of patients with heart failure with preserved ejection fraction
详细描述
Obesity is an independent risk factor for heart failure with preserved ejection fraction (HFpEF), however, the impact of visceral fat area (VFA) in patients with HFpEF is unclear. According to established process of patients' selection, a total of 172 patients whose mean age was 72 years were included in this study, and the median follow-up duration was 395.5 days(interquartile range: 207.5 to 535.5 days). All patients were divided into two groups based on the best cut-off value of VFA, and the primary outcome of this study was all-cause death in patients with HFpEF. The aim of this study was to clarify whether VFA has prognostic value in patients with HFpEF by Kaplan-Meier analysis and cox analysis.
