Themes include the role of exercise, risk factor management, enhanced self-management, technologies to support healthy behaviour, patient education models, and analyzing cardiovascular databases to better understand long-term patient outcomes. The statistics are strong: Participation in cardiac rehabilitation programs, which emphasize exercise, can lower chances of dying from a future cardiac event by about 50%.
