The American College of Cardiology/American Heart Association guidelines suggested that cardiac rehabilitation (CR) should be offered to all eligible patients after coronary bypass surgery (CABG).[1] However, CR use in America is relatively low among Medicare beneficiaries despite convincing evidence of its benefits and recommendations for its use by professional organizations.[2] This neglect is as well evident in Taiwan. Traffic inconvenience and unavailability due to working hours are the common causes. There are ways to mend this situation. One of them is to develop an early, intensive and short-term CR program. The current investigation will adopt an early, intensive and supervised training for male patients following elective CABG due to old myocardial infarction and/or angina pectoris.
