• Sarcopenia (DXA-based low muscle mass and low muscle strength) is a valuable prognostic indicator of all-cause mortality after cardiac surgery. • Recommendation to include chair rise test to screen for physical frailty and sarcopenia, then proceed with muscle mass testing. • Sarcopenia evaluation involves non-invasive, accessible, and simple methods to objectively gauge risk of adverse outcomes post-cardiac surgery. To determine the prevalence...
