AbstractThe hemodynamic effects of intravenously administered adenosine, a potent vasodilator, were examined in 15 patients with pulmonary hypertension. All patients were given adenosine, 50 μg/kg per min, increased by 50 μg/kg per min at 2 min intervals to a maximum of 500 μg/kg per min or until the development of untoward side effects. The patients were then given oral nifedipine, 20 mg every hour, until a ≥20% decrease in pulmonary vascular resistance or systemic hypotension occurred.The administration of maximal doses of adenosine, 256 ± 46 μg/kg per min, produced a 2.4% reduction in pulmonary artery pressure (p = NS), a 37% decrease in pulmonary vascular resistance (p < 0.001) and a 57% increase in cardiac index (p < 0.001). The admini...
