[Long-term results of rehabilitation of heart infarct patients in heart groups. Experience from the Halle/Saale city district].

A eight-year respectively ten-year study from 3285 patients on the prognosis and rehabilitation after definite and possible myocardial infarction of the HIR 1974-1981 was made in Halle/S. The survival rate among the infarction population was 42.1 percent after ten years. The reinfarction rate was 9.8 percent. The rate at which the patients returned to work in relation to all patients who had been fit to work before their first registered infarction is 50.5 percent for population 65 years of age and younger. Acute myocardial infarction was the primary cause of invalidity of 35.4 percent of the patients. Late invalidity was 23.2 percent. After ten years 37.8 percent of the patients took up full-time employment. The kinetotherapy in the phase II and/or III of the rehabilitation may be carried out by 367 patients (age 50.4 +/- 6.3 years) = group II and was not carried out by 242 patients (age 52.3 +/- 7.2 years) = group I. The lethality was in group I 55.9 respect. 28.3 percent in group II after eight years. Mortality after reinfarction was in physically active group II less than in inactive group I. The late invalidity was in active group II greater (16.9 percent) than in inactive group I (9.1 percent). By the long-time rehabilitation under doctors control were the complications of the coronary heart disease decreased.
