Overview

Sarcopenia is a skeletal muscle disease, characterised by low muscle strength and muscle mass, and associated with higher medical care costs, shorter life expectancy and physical dependence. Sarcopenia affects around 1 in 10 older adults in the general population. However, in patients with coronary heart disease (CHD), this number is almost 3 in 10. Patients who have CHD are offered cardiac rehabilitation (CR); a multicomponent programme designed to improve long-term health outcomes. Nutritional education is an important part of CR and typically focuses around modifying fat and carbohydrate intake to lower cholesterol levels and achieve a healthy weight. Currently there is little focus on increasing protein intake, which might reduce the risk of sarcopenia. Eligible patients with CHD and low protein intake will receive the standard nutritional education delivered during CR. Next, participants will be randomised to one of two groups: protein education (intervention), or standard information (control). Whilst COVID-19 restrictions are in place, education will be delivered remotely via pre-recorded video. Outcome measures, including protein intake, sit to stand performance, sarcopenia risk score (modified SARC-F), Physical Activity Vital Signs (PAVS) and waist circumference, will be assessed at baseline, at the end of the standard CR programme and after a follow-up period of the same duration as the CR programme.
