In a double-blind, randomized placebo controlled study, the effect of intracoronary (IC) nicardipine (0.4 mg) on methylergonovine (0.4 mg) induced coronary artery spasm was assessed in 16 patients with a history of variant angina. Reversal of the methylergonovine-induced coronary artery spasm was observed in 100% of patients treated with IC nicardipine and 25% of patients treated with placebo (p less than 0.01). There were no significant differences between the nicardipine and placebo treatment groups with respect to heart rate, blood pressure, proportion of patients experiencing chest pain or ST segment changes. These findings demonstrate that IC nicardipine is safe and could be effective in the reversal of coronary artery spasm in patients with variant angina.
