Effect of amlodipine + candesartan on cardiovascular events in hypertensive patients with coronary artery disease (from The Heart Institute of Japan Candesartan Randomized Trial for Evaluation in Coronary Artery Disease (HIJ-CREATE) Study).

摘要

Combination therapy with calcium channel blockers and angiotensin II receptor blockers is recommended as one of the effective therapies for hypertension. However, it remains unclear whether this combination reduces major adverse cardiovascular events (MACEs) in patients with hypertension with coronary artery disease (CAD). The purpose of the present study was to examine the effects of amlodipine plus candesartan on MACEs in patients with hypertension with CAD. The study population was drawn from The Heart Institute of Japan Candesartan Randomized Trial for Evaluation in Coronary Artery Disease (HIJ-CREATE), which was a multicenter, prospective, randomized controlled trial including 2,049 patients with hypertension with angiographically documented CAD. Subgroup analysis was performed in patients treated with amlodipine at baseline (n = 388). The median follow-up period was 4.3 years. Treatment using amlodipine plus candesartan reduced the risk for MACEs by 39% (p = 0.015) compared to that using amlodipine without angiotensin II receptor blockers. Among the individual events constituting MACEs, the incidence of unstable angina pectoris requiring hospitalization was significantly lower, by 52% (p = 0.007). In conclusion, amlodipine plus candesartan demonstrated a more favorable effect on reducing cardiovascular events in patients with hypertension with CAD compared to amlodipine-based therapy without candesartan.
