The epidemiologic evidence examining the effect of physical activity on the development and course of coronary heart disease is reviewed. This evidence indicates that physically active individuals have a lower incidence of myocardial infarction and mortality from coronary disease. While there is no documentation that an exercise program following myocardial infarction will significantly increase patient survival, exercise does increase functional capacity, lessen angina pectoris, and improve self-image in patients with coronary heart disease. Possible mechanisms for the beneficial effects of exercise are considered.
