Effectiveness of Social Incentive and Digital Exercise Prescriptions to Improve Cardiovascular Fitness Among High-Risk Patients

Principal Investigator: Christopher Kusmiesz, MS

Consistent exercise has been shown to reduce the risk of developing cardiovascular disease as well as improve the prognosis of patients with existing cardiovascular disease. Many physicians encourage their patients to exercise regularly to obtain these risk reducing health benefits. However, exercise compliance has been shown to be relatively low and physicians do not have the time or ability to continually follow-up with patients to track their exercise adherence and/or progress. With the recent improvement of wearable fitness technology, it has become possible to remotely monitor a patient’s exercise habits and adherence. Coupling wearable technology with constant monitoring and real time feedback by their physician, provides a potentially scalable solution to motivating patients and improving physical activity levels.

The primary aim of this study is to examine the feasibility and effectiveness of a comprehensive exercise prescription program with monitoring and regular feedback from the patient’s cardiologist. Patients will be provided with a wearable fitness device linked to Way to Health. The study will consist of a 24-week intervention period. Patients will receive an individualized exercise prescription with comprehensive pre and post intervention as per the Penn Sports Cardiology and Cardiac Fitness program clinical protocol. Daily time spent in target activity intensity ranges as well as the number of daily steps taken will be monitored. Based on attainment of targets, patients will receive personalized text messages from their cardiologist. The primary measure will be exercise capacity as measured by cardiopulmonary testing with several secondary measures of fitness and cardiovascular health.
