Prevention of diabetes in hypertensive patients: Results and implications from the VALUE trial

Abstract

A growing number of experimental and clinical studies have provided evidence indicating that pharmacological blockade of the renin-angiotensin system (RAS) by either angiotensin-converting enzyme inhibitors or angiotensin type 1 receptor blockers reduces the incidence of new onset type 2 diabetes in subjects with hypertension and/or cardiovascular disease, independently of antihypertensive and cardiovascular protective effects. The beneficial effects of RAS inhibition on the development of diabetes have been largely attributed to improvements in peripheral insulin sensitivity and glucose metabolism. This review focuses on recent experimental and clinical evidence supporting the role of RAS inhibition in the reduction of new onset type 2 diabetes and the mechanisms that may be involved. © 2009 Zhou and Schulman, publisher and licensee Dove Medical Press Ltd.
