Renin News and Research

RSS

Renin, also known as angiotensinogenase, is an enzyme that participates in the body's renin-angiotensin system (RAS) that mediates extracellular volume (i.e., that of the blood plasma, lymph and interstitial fluid), and arterial vasoconstriction. Thus, it regulates the body's mean arterial blood pressure.

Use of RAAS inhibitors reduced aneurysm rupture risk by 18%, finds study

A multi-center study of more than 3,000 people with high blood pressure and brain aneurysms found that the use of RAAS inhibitors, a class of blood pressure lowering medications, reduced the risk of an aneurysm rupture by 18%, according to new research published today in Hypertension, a peer-reviewed journal of the American Heart Association.
