[Cardiac rehabilitation in patients with myocardial infarction: a 10-year follow-up study].
INTRODUCTION AND OBJECTIVES Very little information is available on the effect of cardiac rehabilitation programs on long-term survival . The primary aim of this study was to assess the effect of a structured cardiac rehabilitation program on mortality in patients who had suffered acute myocardial infa rct ion . The secondary endpoint was the effect on morbidity . PATIENTS AND METHOD The study included 180 low-risk male patients aged under 65 years . Patients were r and omly assigned to one of 2 groups : 90 entered into a comprehensive cardiac rehabilitation program , and 90 served as a control group . The mean follow-up period was 10 years . RESULTS All-cause mortality was significantly lower in the intervention group : the 10-year survival rate was 91.8 % in the intervention group compared with 81.7 % in the control group ( P=.04 ) . There was also a decrease in cardiovascular mortality , though it was not statistically significant : the 10-year survival rate was 91.8 % in the intervention group compared with 83.8 % in the control group ( P=.10 ) . The incidence of non-fatal complications was lower in the intervention group ( 35.2 % vs 63.2 % , P=.03 ) , as was the incidence of unstable angina ( 15.7 % vs 33.9 % , P = .02 ) and cardiac heart failure ( 3.0 % vs 14.4 % , P=.02 ) , and the need for coronary intervention ( 8.4 % vs 22.9 % , P=.02 ) . CONCLUSIONS The application of a comprehensive cardiac rehabilitation program significantly decreased long-term mortality and morbidity in low-risk patients after acute myocardial infa rct ion
