Non-dominant handgrip strength is associated with higher cardiorespiratory endurance and elevated NT-proBNP concentrations in ambulatory male adult outpatients with stable HFrEF.

Understanding the significance of handgrip strength is essential for identifying frailty in heart failure patients. The aim of this study was to identify the association between handgrip strength and cardiorespiratory endurance while highlighting the importance of the musculoskeletal system in cardiac rehabilitation for patients with heart failure. An observational cross-sectional study was conducted at Harapan Kita Hospital, Jakarta, Indonesia, from April 2022 to April 2023, among patients with heart failure with reduced ejection fraction (HFrEF) attributed to cardiomyopathy or coronary artery disease.
