[Hemodynamic study of dopamine used in chronic heart failures and in cardiogenic shock as a complication of acute myocardial infarct].
The object of this study is to examine the properties of dopamine at the hemodynamic and renal level in 16 patients with decompensated chronic cardiopathies or very serious cardiogenic shock due to myocardial infarction. The results show an increase in the cardiac index in 75 p. 100 of the cases with a favourable diminution of the arterio-venous difference in O2 and of the pulmonary arterial resistances. The most noticeable and the most constant effect is the recovery and increase of the diuresis. Positive chronotropic and bathmotropic effects were observed which necessitated the limitation of prescription of dopamine in those subjects showing signs of disturbances in ventricular excitability.
