Abstract Background: Handgrip strength (HGS) is a key indicator of overall muscle strength and functional capacity in patients with heart failure (HF). However, no reference equations specific to this population have been previously published. Objectives: This study aimed to develop and validate a reference equation for predicting HGS in patients with HF. Methods: A cross-sectional study was conducted on patients with stable HF, aged 18–79 years, diagnosed for at least three months. Maximum HGS value was obtained from three consecutive […]
