[Mortality of patients with a history of acute myocardial infarct 3 months after the disease].

The lethality rate of patients with past myocardial infarction after the third month of the infarction is discussed. Two groups of patients with past myocardial infarction were followed up for 4 years after the third month of the infarction. The basic group included patients who carried out a rehabilitation program while the patients in the control group were not included in any kind of rehabilitation. At the of the first year the lethality rate of the basic group of patients was 5.71%% while of the control group it was 8.82%. In the second year the lethality rate fell in the basic group to 4.55% and in the control group to 6.45%. In the third year the lethality rate was 3.17% for the basic group and 3.45% for the control group, and in the fourth year it was 1.63% for the basic group and 3.57% for the control group. The rehabilitation program carried out with the patients of the basic group had exerted a favorable influence on the survival of the patients and had led to a lower total lethality rate of 15.06% compared to that of 22.29% of the control group for the whole four year period of observation. The physical rehabilitation reduces the known until now factors of increased risk as well as the possibility for a new infarction.
