Two years after completing a 1-month residential rehabilitation program, post-MI and post-CABG patients maintained a 34% higher mean exercise capacity compared to baseline (P<0.01).
Cohort (n=78)
Does a 1-month concentrated residential rehabilitation program improve long-term exercise capacity and physical activity patterns in post-myocardial infarction and post-coronary artery bypass surgery patients?
A 1-month concentrated residential cardiac rehabilitation program leads to sustained improvements in exercise capacity and physical activity levels at 2 years post-myocardial infarction or coronary artery bypass surgery.
Effect estimate: 34% increase
p-value: p=<.01
BACKGROUND: The benefits of exercise training for postmyocardial infarction and postcoronary artery bypass surgery patients are well established, but little is known about the effects of rehabilitation in the months or years following the program. The purpose of this study was to assess exercise capacity, blood lipids, and physical activity patterns 2 years after completing a concentrated residential rehabilitation program in Switzerland. METHODS: Seventy-eight patients (86% males, mean age = 56 +/- 10, mean ejection fraction = 64% +/- 12%) were referred to a residential rehabilitation program after a myocardial infarction or coronary artery bypass surgery between January 2001 and June 2001. Patients lived at the center for 1 month, during which time they underwent educational sessions, consumed a low-fat diet, and exercised 2 hours daily. Two years after completing the program, patients returned to the hospital and underwent a maximal exercise test, an assessment of recent and adulthood physical activity patterns, and evaluation of blood lipids. RESULTS: During the 2-year follow-up period, there were 5 deaths, and 70 of the remaining 73 patients returned for repeat testing. Mean exercise capacity increased 27% during the rehabilitation program (P < .01). Gains in exercise capacity during rehabilitation were maintained after the follow-up period; mean exercise capacity after 2 years was 34% higher compared with that at baseline (P < .01). At the 2-year evaluation, patients were expending a mean of 3127 +/- 1689 kcals/wk during recreational activities compared with 977 +/- 842 kcals/wk during adulthood prior to their cardiac event (P < .001). Between the completion of rehabilitation and the 2-year follow-up, total cholesterol, total cholesterol/high-density lipoprotein ratio, and triglycerides increased significantly. CONCLUSIONS: Two years after a cardiac event and participation in a concentrated residential rehabilitation program, patients maintained their exercise capacity and engaged in physical activities that exceed the levels recommended by guidelines for cardiovascular health. These observations suggest that a relatively intensive rehabilitation program provided a catalyst to maintain physical activity patterns and exercise tolerance in the 2 years following a cardiac event.
Jean Jobin (Tue,) conducted a cohort in Post-myocardial infarction and post-coronary artery bypass surgery (n=78). Concentrated residential rehabilitation program vs. Baseline / prior to cardiac event was evaluated on Exercise capacity (34% increase, p=<.01). Two years after completing a 1-month residential rehabilitation program, post-MI and post-CABG patients maintained a 34% higher mean exercise capacity compared to baseline (P<0.01).
