This study is looking at ways to improve fitness in older adults (65 years and older) who have recently had a heart attack (myocardial infarction) or a heart procedure like an angioplasty, stent placement, or valve replacement. Participants will be enrolled in a Phase 2 Cardiac Rehabilitation program. The study compares two types of exercise training: High Intensity Interval Training (HIIT) and Moderate Intensity Training (MICT). The goal is to see which training method is better at improving your aerobic fitness and physical function, measured by how well you can do a 30-second sit-to-stand test. The study aims to enroll 114 participants.
