Cardiac rehabilitation after myocardial infarction. Combined experience of randomized clinical trials.
R and omized clinical trials of cardiac rehabilitation following myocardial infa rct ion have typically demonstrated a lower mortality in treated patients , but with a statistically significant reduction in only one trial . To overcome the problem of not being able to detect small but clinical ly important benefits in mortality in r and omized clinical trials of exercise and risk factor rehabilitation after myocardial infa rct ion with small numbers of patients , we carried out a meta- analysis on the combined results of ten r and omized clinical trials that included 4347 patients ( control , 2145 patients ; rehabilitation , 2202 patients ) . The pooled odds ratios of 0.76 ( 95 % confidence intervals , 0.63 to 0.92 ) for all-cause death and of 0.75 ( 95 % confidence intervals , 0.62 to 0.93 ) for cardiovascular death were significantly lower in the rehabilitation group than in the control group , with no significant difference for nonfatal recurrent myocardial infa rct ion . These results suggest that , for appropriately selected patients , comprehensive cardiac rehabilitation has a beneficial effect on mortality but not on nonfatal recurrent myocardial infa rct ion
