Frailty is a state of decreased physiologic reserves and vulnerability to stressors.
Several tools exist to measure frailty, some based on physical tests and others on
questionnaires, yet there is no agreement on which tool to recommend. This multi-center
prospective cohort study is aimed at comparing various frailty assessment tools to determine
which best predicts death or major complications after cardiac surgery or transcatheter
intervention. The population of interest is elderly patients with severe aortic stenosis
undergoing surgical or transcatheter aortic valve replacement. The frailty assessment tools
under investigation include composite frailty scales, physical performance tests, muscle
mass, and biomarker expression. The overall objective is to improve our ability to predict
risk by measuring frailty using the optimal tool in elderly cardiovascular patients.
