Text: Quantitative angiographic evaluation of the influences of nifedipine (Group 1, 12 patients, 10 mg sublingually) and propranolol (Group 2, 12 patients, 0. 1 mg/kg intravenously) on the residual lumen diameter of one significant coronary stenosis in each patient showed that (1) after nifedipine, the lumen was unchanged in one, augmented in seven, and reduced in four cases ; (2) variations ranged between +1. 59 and -1. 2 mm, and their direction correlated closely with the influence of oral nifedipine on the episodes of spontaneous ischemia ; and (3) in no case did treatment with propranolol vary the stenosis lumen by more than 0. 3 mm.
