Dietary Intervention and Physical Activity in Patients With Heart Failure and Reduced Ejection Fraction
Heart failure with reduced ejection fraction (HFrEF) is frequently associated with abnormalities in body composition, including reduced skeletal muscle mass and sarcopenia, which are independent predictors of reduced exercise tolerance, impaired quality of life, and increased mortality. Despite advances in pharmacological therapy, evidence-based non-pharmacological strategies aimed at preventing muscle mass loss remain limited.
This randomized controlled trial aims to evaluate the effects of dietary intervention based on the DASH diet with high-protein elements, resistance exercise training, and their combination on skeletal muscle mass, functional capacity, echocardiographic parameters, biochemical markers, and quality of life in patients with HFrEF.
