Hemodynamic effects of steroids in cardiac disease.

The hemodynamic effects of intravenous methylprednisolone were documented by right heart catheterization in seven patients with an acute uncomplicated transmural myocardial infarction 1 to 9 days after the onset of symptoms. Intracardiac pressures, brachial artery pressure, and cardiac output were determined before and 1 hour after the termination of the methylprednisolone infusion. Two grams of methylprednisolone were infused over a 20 minute period. The brachial pressure rose from a mean of 82 to 90 mm. Hq (N.S.). The brachial artery mean pressure fell in the one patient with a 1-day-old infarction, and it rose in the six patients with an older infarction, from 83 to 94 mm. Hg (p less than 0.01). As the brachial artery pressure rose in one patient, chest pain and marked ST-segment elevation occurred which were relieved by nitroglycerin. This experience promoted us to terminate the steroid study. There was a nonsignificant increase in the cardiac index and wedge pressure. The raise in the brachial artery pressure with an infarction older than 1 day was an unexpected finding, since steroids are presumed to be vasodilating agents.
