A Feasibility Study of the SHAPE17 Test of Aerobic Fitness in Older Adults Presenting for Moderate to High-risk Surgery

What this Trial Is About

Researchers are studying whether the SHAPE-HF cardiopulmonary testing system can be used before surgery to better assess heart, lung, and overall physical fitness in adults over 60 years old. This system aims to provide an objective and simplified way to measure aerobic fitness before moderate- to high-risk noncardiac surgery. The study compares this new testing method with traditional ways of estimating fitness, such as patient questionnaires and self-reported activity levels. Participants will attend one in-person visit lasting about 35 minutes during their preoperative evaluation. During this visit, they will complete the SHAPE-HF submaximal exercise test along with standard assessments like the Duke Activity Status Index and subjective metabolic equivalent (MET) evaluations. Around 24 hours after testing, researchers will follow up by phone to check for any issues. After surgery, medical records will be reviewed for 30 days to see how test results relate to recovery, short-term health problems, and major complications. Throughout the study, participants will provide information about their activity levels and undergo testing to measure aerobic fitness objectively. Researchers will assess recruitment success, compare SHAPE-HF results to conventional fitness measures, and track postoperative outcomes including major cardiovascular events and complications. This study does not change planned surgery or care but seeks to improve risk assessment for older adults undergoing moderate- to high-risk surgery.
