A controlled trial of physical training after myocardial infarction. Effects on risk factors, nonfatal reinfarction, and death.
Abstract The purpose of the trial was to analyze whether supervised physical training could reduce death and nonfatal reinfa rct ion in a nonselected series of postinfa rct patients . All patients born in 1913 and later , who were hospitalized for a myocardial infa rct ion during 1968–1970 in Goteborg Sweden , were r and omized to a training group ( 158 patients ) and a control group ( 157 patients ) . Other treatment was exactly the same and st and ardized for the two groups . Twenty-seven percent were excluded from training . Training started 3 months after the infa rct and was scheduled for three times a week . The training group had higher physical working capacity after 1 yr than the control group . Blood pressure was lower , but there was no differences in blood lipids . During 4 yr of follow-up , 28 patients died in the training group and 35 in the control group . The numbers of nonfatal reinfa rcts were 25 and 28 , respectively . Within the training group patients adhering to the program had lower mortality than those who did not , but the former also had lower initially predicted risk of dying . A special analysis of patients who attended the training program in comparison to matched controls also showed a lower mortality . No differences in mortality between the training group and the control group were statistically significant , however
