[Changes in hemodynamics in acute myocardial infarct following administration of potassium orotate]

The basic hemodynamic indices prior to and post the treatment with potassium orothate were investigated 25 patients with acute myocardial infarction. The method for quantitative investigation of hemodynamics is used by the dilution of colour indicator and recording of the dilution curves with the ear oximeter. The results obtained are compared with those of a control group of 30 patients with the same disease. The data revealed that in the treatment with potassium orothate a more favourable evolution develops in the values of cardiac output, total peripheral vascular resistance and the volume of the circulating blood. The authors associate the more favourable effect of these indices with a faster recovering of the contractibility of the myocardium.
