The antianginal effects of bepridil, a new calcium entry blocker, were evaluated in 20 patients with chronic stable angina in a single-blind trial that was placebo-controlled within patients. Of the 20 patients, 13 also underwent rest and exercise gated blood pool scintigraphy to assess the effects of the agent on left ventricular (LV) performance. Mean anginal frequency was significantly reduced, from 7.3 to 3.1 episodes/week (p less than 0.01). Total work performed increased from 410 to 581 kpm (p less than 0.005), and exercise time increased from 5.3 to 6.6 minutes (p less than 0.005). Supine resting LV end-diastolic volume index, end-systolic volume index, stroke volume index, cardiac index and ejection fraction (EF) were not altered by bepridil. During supine exercise, EF decreased from 60 to 55% during placebo therapy. Despite an increase in total work, the mean EF increased from 60 to 62% (p less than 0.05 vs exercise placebo) during exercise with bepridil therapy. Maximal exercise stroke volume index and cardiac index were significantly greater during bepridil therapy. Exercise resulted in new or increased LV wall motion abnormalities in 7 of 13 patients during placebo therapy. During bepridil therapy, only 4 new or increased wall motion abnormalities were noted despite the increase in total work performed. Thus, bepridil is an effective antianginal agent. The drug allows an increase in exercise work load and preserves LV performance.
