[Effective use of study procedures using instruments in infarct patients before discharge from the clinic].

81 males and 23 females after myocardial infarction at the age of 61 +/- 12 and 69 +/- years, respectively, were examined at the end of the stay in the clinic and after one year by means of ergometry and echocardiography. While at the discharge from the clinic the females reached maximally only 50 Watt, 34.7% of the males transgressed this achievement. Also in the watt pulse and in the product of the pressure frequency these patients reached high values, less frequently showed pathological ST segments under exercise and echocardiographical revealed a smaller left ventricle, a greater shortening fraction as well as more insignificant disturbances of the kinetics. This group-typical behaviour remained up to the first year. In patients with pathological diastolic pressure of the pulmonary artery at rest in 8% the latent left heart insufficiency could clinical not be recognized and in those patients with pathological pressure under exercise 54% finished the ergometry without any other recognizable reasons of discontinuation. Finally, the patients who died up to the first year belonged to the group with complications in the intensive care unit, with high resting pulse rate, pathological diastolic pressure of the pulmonary artery, large left ventricle as well as left atrium and low shortening fraction at rest and low watt-number, when discharged from hospital.
