[Retrospective evaluation of various methods of examination for prognosis of cardiac insufficiency in the subacute period of myocardial infarct].

A retrospective analysis of the informativeness of certain methods of examination for ascertaining the possibility of cardiac failure developing in the subacute period of penetrating, predominantly primary transmural myocardial infarction with no clinical signs of cardiac failure in the first three days after the onset of the disease. In 60 patients circulation time in the "arm--ear" area and in 25 of them the stroke and minute volumes by the dye dilution method were studied. The state of the fluid spaces was investigated in 18 patients and daily natriuresis in 23. In 36 patients the condition of the pulmonary circulation was judged by means of roentgenogram. The high value of the information gained from study of circulation time and natriuresis and X-ray examination in the prognostication of the development of cardiac failure is shown.
