The outcome of STOP-Hypertension-2 in relation to the 1999 WHO/ISH hypertension guidelines.

Abstract

The 1999 hypertension management guidelines issued by the World Health Organization and the International Society of Hypertension emphasize the importance of blood pressure reduction in the prevention of cardiovascular events. Furthermore, they conclude that the benefits of treatment are due to blood pressure lowering per se, rather than to any specific antihypertensive therapy. The results of the second Swedish Trial in Old Patients with Hypertension (STOP-Hypertension-2) are consistent with these recommendations, since in this trial angiotensin converting enzyme (ACE) inhibitors and calcium antagonists reduced blood pressure to the same extent as conventional therapy with beta-blockers and diuretics in elderly hypertensive patients, and the three treatments produced similar reductions in the risk of cardiovascular events. Furthermore, a first subgroup analysis of cardiovascular mortality showed that the three treatments seemed equally effective in diabetic patients. The STOP-Hypertension-2 data, therefore, are fully consistent with the 1999 hypertension management guidelines, and underline the advantages offered by both older and newer antihypertensive therapies.
