[Possibilities of early diagnosis of left-heart insufficiency in acute myocardial infarction].

: In 84 patients with an acute myocardial infarction clinical signs, measurement of the pressure of the pulmonary arteries and radiogramme of the thorax were used and compared for the estimation of the left heart insufficiency-particularly of an increase of a preload. The value of a standardized course series of radiogrammes of the thorax as a non-invasive investigation method in contrast to the invasive method of the pressure measurement of the pulmonary arteries was discussed. Advantages and disadvantages of the two methods were critically shown, since only in about 60% a correspondence was to be recognized.
