Cardiac rehabilitation following coronary artery bypass surgery.
Early expectations of coronary revascularization prolonging life and reducing coronary events have been modified by 15 years' experience to mostly initial palliation of ischemic symptoms. Bypass surgery represents only a single therapeutic aspect for coronary atherosclerosis. Technically successful operations often fail miserably without overall risk factor alteration and functional capacity optimization which progressive exercise initiates during the postoperative period. Regular activity program participation improves physical conditioning, raises the symptom-limited exertional level, lessens post surgical musculoskeletal discomfort, and improves morale. Yet exercise alone without comprehensive secondary prevention and risk factor modification will be no more successful at arresting atherosclerosis than any other single measure. Both operative intervention and vigorous exertion are valuable components of coronary artery disease therapy, but must be part of an all-embracing effort. Whether regular exertion combined with overall risk factor modification will prolong life and reduce future cardiac events or beneficially alter the process of atherogenesis remain areas of avid investigation.
