Abstract
Twenty-eight male cardiac patients who had either experienced myocardial infarction or undergone coronary bypass surgery were assigned to a treatment condition and participated in a 3-month, exercise-based Cardiac Rehabilitation Program, whereas 20 other cardiac patients were assigned to a routine-care condition and did not participate in the rehabilitation program. Cardiovascular, psychological, and psychosocial functioning were assessed before treatment or routine care was begun, after 3 months of treatment or routine care, and 4 months later. Results indicated that patients in the treatment condition evidenced reliably more efficient cardiovascular functioning (resting heart rate, resting diastolic blood pressure, treadmill exercise performance, exercise heart rate, exercise systolic blood pressure), better understanding of heart disease, better understanding of and reported compliance with treatment recommendations, more positive self-perceptions (health, body concept, self-concept, progress toward goals), and better psychosocial functioning (e.g., decreased employmentrelated stress, more active use and enjoyment of leisure time, more physical and sexual activity). Chronic patients benefited as much from the treatment as did acute patients, and the beneficial effects for all treated patients were evident not only just after rehabilitation, but also 4 months later. This investigation appears to be the first such test of effects of this type of treatment, and the results have wide generalizability and applicability.
