Sacubitril/valsartan reduces cardiac decompensation in heart failure with preserved ejection fraction: a meta-analysis

Background: The impact of sacubitril-valsartan on heart failure (HF) patients with preserved ejection fractions (HFpEF) is uncertain. The purpose of this meta-analysis was to explore the clinical advantages and safety of sacubitril-valsartan in patients with HFpEF. Methods: PubMed and Web of Science were searched without any restrictions from inception to 8 May 2022 to identify valuable articles. The studies that met the inclusion criteria were analyzed. Results: Four trials, with a total of 7008 patients were included. Compared with valsartan, sacubitril-valsartan significantly reduced the rate of HF decompensation and of the combined end point of HF decompensation and all-cause mortality. All-cause mortality, New York Heart Association class improvement and rate of hyperkalemia were not significantly different between the two groups. Regarding safety, sacubitril-valsartan was more likely to increase the risk of hypotension. Conclusion: This meta-analysis suggests that sacubitril-valsartan may be an effective strategy to reduce HF decompensation events in patients with HFpEF.Systematic Review registration: CRD42022336077.
