ObjectiveTo systematically evaluate the effect of frailty on the prognosis of patients with heart failure.MethodsComputer searches were conducted on PubMed, Embase, The Cochrane Library, Web of Science, CNKI, Wanfang Data Knowledge Service platform, Weipu full-text database of Chinese scientific and technological journals, and Chinese biomedical literature database from August 12, 2022. After literature screening was completed by two researchers, the data extraction (such as study type, sample size, age of included patients, New York Heart Association (NYHA) Functional Classification, frailty assessment tool, frailty positive rate, outcome indicators, etc.) was performed and the risk of bias in the included studies was assessed. Meta-analysis was performed using Revman 5.4 and Stata 14.0 software.ResultsA total of 32 studies were included, including 406,269 patients with heart failure. All included studies were rated high overall quality. The results of meta-analysis showed: Frailty increases the risk of all-cause death in patients with heart failure (hazard ratio [HR] = 1.73, 95% confidence interval [CI]: 1.50 - 2.00, p < 0.001), unplanned readmission (HR = 1.96, 95% CI: 1.21 - 3.17, p = 0.006), and joint endpoint risk (HR = 1.66, 95% CI: 1.48 - 1.86, p < 0.001).ConclusionCurrent evidence suggests that frailty increases the risk of all-cause death, unplanned readmission, and joint endpoints in patients with heart failure.© 2024 John Wiley & Sons Ltd.
