Short physical performance battery in the pre and postoperative myocardial revascularization surgery in older adults: Reliability, hemodynamic responses, subjective perceived exertion, and adverse events.

Introduction: The Short Physical Performance Battery (SPPB) may be feasible for evaluating older adults undergoing myocardial revascularization surgery (MRS). However, it is necessary to verify its measurement properties and safety to use it for clinical practice.

Objective: To investigate the reliability, hemodynamic responses, subjective perceived exertion (SPE), and adverse events during and after SPPB in older adults undergoing MRS.
