Abstract
To the Editor: We have studied the clinical and hemodynamic effects of parenteral diazoxide in nine symptomatic patients with proved primary pulmonary hypertension, and the effects of oral diazoxide in seven of the same patients.1 After incremental injections of a total of 300 to 600 mg of diazoxide into the pulmonary trunk, changes in pulmonary-artery mean pressure were insignificant. However, the pulmonary blood flow increased in every case by 1.2 to 3.2 liters per minute, rising from an average control level of 3.1 to an average of 5.4 liters per minute (P<0.001). The pulmonary vascular resistance likewise fell in every.
