[The ACCOMPLISH trial: are results really unexpected?].

The ACCOMPLISH trial consists of a randomized morbidity-mortality study involving 11506 hypertensive patients at high cardiovascular risk, randomly allocated to a fixed dose combination containing an angiotensin converting enzyme inhibitor (B, benazepril) and either a calcium antagonist (A, amlodipine) or a diuretic (HCTZ, hydrochlorothiazide). The target blood pressure (< 140/90 mmHg) was achieved after a 6 month titration period in 75.4% of patients receiving B+A, versus 72.4% in those on B + HCTZ. Over a mean follow-up of 3 years, the B + A drug regimen was found to reduce significantly more effectively the relative risk cardiovascular mortality (-20%), fatal and non fatal myocardial infarction (-22%) and coronary revascularization (-14%), appearing therefore particularly effective to prevent complications due to myocardial ischemia.
