Reduction in sudden deaths and coronary mortality in myocardial infarction patients after rehabilitation. 15 year follow-up study.
The study was set up to evaluate the long-term effects on mortality of a comprehensive rehabilitation and secondary prevention programme lasting 3 years after acute myocardial infa rct ion . The study group consisted of 375 consecutive , non-selected patients under 65 years of age r and omly allocated to an intervention group ( 188 patients ) or a control group ( 187 patients ) . After 15 years follow-up significantly lower incidence of sudden death ( 16.5 % vs 28.9 % , P = 0.006 ) and coronary mortality ( 47.9 % vs 58.5 % , P = 0.04 ) were seen in the intervention group compared with controls . Total mortality was 64.4 % and 66.8 % , respectively ( ns ) . The incidence of cancer death was 16 in the intervention group and three in the controls . Cardiac failure , enlarged heart , New York Heart Association functional class II or more and membership in the control group were significantly associated with coronary mortality during the first 3 years , and after 3 years enlarged heart , diabetes and reinfa rct ion were associated with late coronary death . Thus , comprehensive multifactorial intervention after acute myocardial infa rct ion had favourable long-term effects on coronary mortality and sudden death but no effect on total mortality
