Adding objectivity to submaximal exercise testing by assessment of heart rate recovery at home—a healthy volunteer study iv (search-iv)

Le résumé fourni par la source

The number of older, frail, and comorbid patients undergoing high-risk surgeries is rising leading to demand for a robust perioperative risk assessment framework. The current ‘gold-standard’ cardiopulmonary exercise testing (CPET) is expensive and not tolerated by all patients. submaximal exercise tests (SETs) provide an accessible alternative for assessing patient fitness. Our group has demonstrated quantifying heart rate recovery (HRR) after SETs by calculation of area under the (heart rate vs time) curve (AUC) has value in predicting postoperative complications.1 However, this method still requires laboratory testing and is an inefficient use of clinician and patient time. The fields of digital health and wearable technology may offer solutions. This study aims to assess the feasibility, acceptability, and reproducibility of conducting community-based SETs by means of wearable technology.
