Cardiac rehabilitation is a safe and effective treatment for cardiovascular patients with acute myocardial infarction, stable angina, coronary bypass surgery, percutaneous coronary intervention, valvular surgery, heart failure, cardiomyopathy and heart transplantation. 

Phase 1 rehabilitation (inpatient setting) revolves around daily activities. Phase 2 rehabilitation (after discharge) is a 3-to-6 months outpatient training program focusing on cardiopulmonary endurance and muscle strength training. Phase 3 rehabilitation encourages patients to maintain exercise habit, control cardiovascular risk factors, and decreasing risk of cardiovascular events. Cardiac rehabilitation improves exercise endurance and life quality, decreases re-hospitalization rate, re-infarction risk, and overall mortality.
