CardioHeartConnect: Commercially Available Fitness for Cardiac Rehabilitation

Participants in the CardioHeartConnect group engage in an eight-week digital cardiac rehabilitation program using the commercially available Peloton app. The intervention includes two daily modules (10-25 minutes total) on weekdays, focused on walking, strength, low-intensity cardio, yoga, pilates, and stretching. Modules progress in intensity over time. The program is delivered through the Ortus-iHealth platform, which prompts daily participation and integrates survey responses and smartwatch data. The intervention is designed to support physical activity, functional capacity, quality of life, and cardiovascular health among patients recovering from Transcatheter Aortic Valve Replacement (TAVR).

CardioHeartEd is the control condition in which participants receive weekly cardiac rehabilitation-related educational resources through the Ortus-iHealth platform for eight weeks. The content is created by the American College of Cardiology and is designed to promote cardiovascular health following TAVR. Participants also receive a smartwatch to wear for self-monitoring, but do not receive structured exercise content. The CHE group controls for access to technology and general education about heart health.
