Left ventricular performance was assessed in ten patients with acute myocarditis during the acute stage (within the first 3 days after the onset of cardiac symptoms) and during the convalescent phase (3-5 weeks later). In nine, the diagnosis was confirmed by endomyocardial biopsy during the acute stage, when left ventricular function was markedly reduced, i.e., cardiac index 1.53 +/- 0.33 l/min/m2 (mean +/- SD), left ventricular stroke work index 14.1 +/- 3.9 g/beat/m2, pulmonary capillary pressure 25.9 +/- 4.3 mm Hg, and systemic vascular resistance 27.9 +/- 9.4 R units. During convalescence, seven patients improved clinically with normal cardiac function and in three it remained impaired. Cardiovascular response to nitroglycerin ointment in three patients and a combination of dopamine and nitroglycerin ointment in five were compared. Nitroglycerin ointment reduced pulmonary capillary pressure by an average of 28.5% (P less than 0.05) and systemic vascular resistance by 26.8%, while the cardiac index increased by 34.1% (P less than 0.05) and left ventricular stroke work index by 30.3% (P less than 0.01). The combined therapy was more effective, with a reduction of pulmonary capillary pressure by 30.4% (P less than 0.05) and systemic vascular resistance by 27.5% (P less than 0.05), accompanying an increase in cardiac index by 53.5% (P less than 0.005) and left ventricular stroke work index by 63.5% (P less than 0.01), with little change in the double products. This study suggests that serial hemodynamic monitoring accurately evaluates cardiac function, selection of appropriate therapy, and the hemodynamic effects of treatment in patients with acute myocarditis.(ABSTRACT TRUNCATED AT 250 WORDS)
