Results and clinical implications of the CAPARES trial.
The Coronary AngioPlasty Amlodipine REStenosis Study (CAPARES) is a multicentre, double-blind, placebo controlled restenosis trial investigating the effect of amlodipine on angiographic and clinical endpoints in patients undergoing routine percutaneous transluminal coronary angioplasty (PTCA) for stable angina pectoris. A total of 635 patients were randomized to amlodipine or placebo two weeks before PTCA and were followed for four months after PTCA. There were 451 nonstented patients who completed the study with angiographic follow-up. Quantitative coronary angiography revealed that the loss in minimal luminal diameter from immediately after PTCA to the four-month follow-up was unaffected by amlodipine treatment. However, the incidence of repeat PTCA and composite clinical events were significantly lower in patients treated with amlodipine.
