Verapamil and angiotensin-converting enzyme inhibitors in patients with coronary artery disease and reduced left ventricular ejection fraction.
Verapamil is effective as antianginal medication but contraindicated in patients with congestive heart failure. Angiotensin-converting enzyme (ACE) inhibitors improve survival in patients with congestive heart failure but have limited effect on patients with angina pectoris. No studies have been published on the combined treatment with verapamil and ACE inhibitors in patients with stable angina pectoris and left ventricular dysfunction. We performed an open study in 14 patients with angina pectoris and ejection fraction < 40%. The patients received verapamil 180 mg and trandolapril 2 mg twice daily for 3 months. We found a significant increase in ejection fraction from 28 +/- 6 to 35 +/- 11 (p < 0.03), wall motion index from 1.0 +/- 0.3 to 1.2 +/- 0.3 (p < 0.03), exercise duration from 6.9 +/- 2.5 to 7.7 +/- 2.9 minutes (p < 0.01), and ratio of exercise to rest rate-pressure product from 2.2 +/- 0.4 to 2.5 +/- 0.6 (p < 0.02). Use of nitroglycerin and number of angina pectoris attacks were both significantly reduced after 3 months of treatment. These findings support the hypothesis that the combination of verapamil and trandolapril is useful in patients with attenuated left ventricular function and angina pectoris.
