Title: Slow-release gallopamil evaluated by exercise test and long-term electrocardiography. Author: Steinbeck G, Reuschel-Janetschek E. Journal: J Cardiovasc Pharmacol; 1992; 20 Suppl 7():S83-7. PubMed ID: 1284162. Abstract: The effects of slow-release gallopamil (100 mg b.i.d.) were studied on exercise-induced ST-segment depression as well as on spontaneous myocardial ischemia detected by long-term electrocardiography (ECG) monitoring for 48 h in 26 patients with coronary artery disease and angina pectoris. Eight patients had to be excluded (because of paroxysmal atrial fibrillation in four patients, development of unstable angina pectoris in three patients, and frequent ventricular premature beats in one patient). In the remaining 18 patients, gallopamil led to an increase of work load (W x min) evaluated by bicycle ergometry, paralleled by an increase of exercise duration until the occurrence of ST-segment depression of > or = 0.1 mV in the nonblinded part of the trial. The number of spontaneous episodes of myocardial ischemia during long-term ECG recording, ranging from 0 to 14 during control, decreased in patients with two or more episodes during control, paralleled by a decrease in the total duration of ischemic episodes and a decrease in the ischemic score (duration of episodes x maximal ST-segment depression). During long-term ECG monitoring, we observed asymptomatic episodes of spontaneous second degree atrioventricular block of the Wenckebach type in three patients. No other adverse effects of slow-release gallopamil were observed. Therefore, these preliminary results of the non-blinded protocol confirm the anti-ischemic effects of slow-release gallopamil given 100 mg b.i.d.; however, these promising results will have to be confirmed in the consecutive double-blind, placebo-controlled part of the trial.[Abstract] [Full Text] [Related] [New Search]
