[Treating hypertension is more important than the choice of agent; results from the largest clinical trial until now].

Abstract

During the past few years, several randomised trials have compared the effects of older blood-pressure lowering drugs (diuretics, beta-blockers) with those of newer ones (angiotensin converting enzyme (ACE) inhibitors, calcium entry blockers) on the long-term prognosis. In general, no significant differences were found between these regimes. Recently, the ALLHAT trial, which was the largest hypertension trial ever and in which over 40,000 patients with hypertension participated, was completed. The initial treatment consisted of either the diuretic chlorthalidone, the calcium entry blocker amlodipine, the ACE inhibitor lisinopril, or the alpha-blocker doxazosin. The latter arm was prematurely discontinued because of a higher incidence of the secondary endpoint heart failure and stroke. Based on an intention-to-treat analysis, the other types of treatment proved to be equivalent in terms of the primary endpoint, a composite of fatal coronary heart disease and non-fatal myocardial infarction. Although the investigators conclude that ALLHAT suggests that thiazide diuretics should be first choice in the treatment of hypertension, there are several caveats that tend to lessen the strength of this conclusion.
