HEMODYNAMIC ALTERATIONS IN ACUTE MYOCARDIAL INFARCTION. I. CARDIAC OUTPUT, MEAN ARTERIAL PRESSURE, TOTAL PERIPHERAL RESISTANCE, “CENTRAL” AND TOTAL BLOOD VOLUMES, VENOUS PRESSURE AND AVERAGE CIRCULATION TIME 12

Abstract

The hemodynamic abnormalities associated with severe myocardial infarction were a reduction of cardiac output (Hamilton dye method), especially stroke volume; an increase of total peripheral resistance, heart rate, central venous pressure and avg. circulation time; a slight and possibly insignificant reduction of total blood volume; and an essentially normal central blood volume. The less severe cases did not exhibit these abnormalities.
