Effect of Sacubitril-Valsartan on Quality of Life, Functional and Exercise Capacity in Heart Failure with Preserved Ejection Fraction (HFpEF): A Systematic Review of Randomized Clinical Trials

Abstract

Background: Sacubitril/Valsartan use in heart failure has shown promising results in early trials. However, the effects on the overall functional capacity, exercise capacity, and quality of life are unknown. Aims: We aimed to understand the results of studies that attempted to measure these outcomes that affect the mobility and day-to-day life of these patients. Methods: MEDLINE, PubMed, PubMed Central (PMC), Google Scholar, ClinicalTrials.gov, and ISRCTN were explored to look for clinical trials relevant to the literature. Results: A total of three high-quality randomized controlled trials were discovered that evaluated the effect of sacubitril-valsartan on functional capacity, exercise capacity, or quality of life. All of them were industry-funded and revealed no statistical difference in the mentioned outcomes. No study measured peak oxygen uptake or ventilation/carbon dioxide ratio slope. Conclusion: Sacubitril-valsartan had minimal to no impact on functional capacity, exercise capacity, or quality of life. However, future prospective studies with more sensitive outcome measures should be conducted to validate the findings.
