Fig. 1 The design of the study. After the first 2 successive exercise tests, patients were randomized to receive either nisoldipine 10 mg twice daily or a placebo for 2 days. On day 2 the coronary angiography was performed. The second pair of successive exercise tests was performed on day 3 at least 2 hours after the last dose of nisoldipine or placebo.
