Risk Factors In Heart Failure Patients With Preserved Ejection Fraction

Overview

This study aimed to identify the independent risk factors associated with heart failure readmission, cardiac mortality and all-cause death among patients discharged from Xiangtan Central Hospital with heart failure and preserved ejection fraction (HFpEF). Understanding related risk factors might add future clinical decision making for individualized post discharge management of HFpEF patients aiming to improve the outcome of discharged HFpEF patients.

This study sought to determine the independent risk factors linked to endpoint events (which include all-cause mortality or readmission for heart failure, cardiovascular death) among hospitalized patients with heart failure and preserved ejection fraction (HFpEF) at Xiangtan Central Hospital during the period from May 1, 2014, to January 31, 2023. The clinical follow up ended on January 31, 2024. The study examined the risk factors associated with the endpoint outcome (cardiovascular death and death from any cause and readmission due to heart failure) to provide clinical evidence for intervening discharged HFpEF patients, with the objective of improving patient outcomes in future clinical practice. The clinical features of hospitalized heart failure with preserved ejection fraction (HFpEF, EF≥50%) are analyzed retrospectively by reviewing the patient's demographic, clinical data, including patient medical history, initial clinical evaluations, and therapeutic interventions, as well as echocardiographic data in the hospital's electronic health records and relevant databases. The clinical outcome of enrolled patients are obtained through a team of three experienced cardiologists and twelve nursing professionals through outpatient consultations, telephone follow-ups, and community visit. The primary endpoint events are all-cause mortality, the second endpoints are the composite cardiovascular death and heart failure readmission.
