In 1981, a large, double-blind, randomized, multicenter trial was started in The Netherlands to evaluate the therapeutic effects of nifedipine or metoprolol in patients with unstable angina. This study, called the Holland Interuniversity Nifedipine Trial (HINT), included several hundred patients to establish potential therapeutic effects. From December 1982 until January 1984 the effects of nifedipine on left ventricular (LV) performance in a subgroup of 37 HINT patients were studied using radionuclide techniques. All patients (18 treated with nifedipine, 19 with placebo) underwent radionuclide angiography and 33 underwent thallium-201 scintigraphy just before and 48 hours after the start of treatment with the experimental medication. Radionuclide angiographic studies were also performed 1 hour (29 patients) and 4 hours (31 patients) after the start of treatment. The thallium-201 images showed defects in 24 (73%) of the baseline images and in 21 (64%) of the 48-hour images. No significant differences were seen between patients receiving nifedipine or placebo in the incidence of new defects or in the disappearance of defects at 48 hours. Changes in thallium-201 images were not related to recurrence of myocardial ischemia or the development of acute myocardial infarction. Nineteen of the 37 patients (51%) with baseline blood pool images had a reduced LV ejection fraction (EF) (38 +/- 10%) and 18 patients (49%) had a normal LVEF of 56 +/- 5%. LVEF improved after 48 hours in 8 patients receiving nifedipine and in only 1 patient receiving placebo (p less than 0.02). This effect was not present at 1 and 4 hours after treatment.(ABSTRACT TRUNCATED AT 250 WORDS)
