Angiotensin receptor blockers and secondary stroke prevention: the MOSES study

Abstract

Hypertension control is critical to prevent stroke. With several clinical trials conducted over the last decade, it seems that the use of an angiotensin-modulating antihypertensive agent conveys benefits beyond blood pressure reduction. Currently, there is evidence supporting the use of either an angiotensin receptor blocker or an angiotensin-converting enzyme inhibitor in the primary-prevention context. However, in the secondary prevention of stroke, the choice of agent is less clear. There is evidence that intensive blood pressure reduction with a combination of an angiotensin-converting enzyme inhibitor and a diuretic can reduce stroke recurrence, but do angiotensin receptor blockers have the same ability? The Morbidity and Mortality after Stroke, Eprosartan Compared with Nitrendipine for Secondary Prevention (MOSES) trial endeavors to answer this question and strives to demonstrate the benefit of angiotensin receptor blockers in the secondary prevention of stroke.
