Is renin a risk factor?

Abstract

1. These results show that elevated blood pressure and a hyperlipidemic diet exacerbate atherogenesis in the two kidney, one-clip hypertensive rabbit. Elevated PRA activity was not essential for the hypertension and did not exacerbate atherogenesis. 2. In addition, the experimentally induced, low renin state following DOC-saline did not result in a protective effect on cardiovascular lesions in rabbits fed an atherogenic diet when compared to normal renin controls. 3. Thus, in these experiments neither an increase in plasma renin accelerated atherogenesis, nor did a decrease in PRA slow the rate of production of atherosclerosis in the rabbit. 4. These observations lend no support to the thesis that renin is an independent risk factor when it is generated within the body in response to these stimuli. Indeed, it suggests that in this setting other factors, not PRA, are responsible for both hypertension in the two-kidney, one-clip rabbit and the arterial damage which occurs in this hypercholesterolemic model.

Atherosclerosis Disease Progression

Atherosclerosis is the buildup of plaque on artery walls, causing stenosis which can eventually lead to clinically apparent cardiovascular disease. Find the latest research on atherosclerosis disease progression here.

Cardiovascular Disease Pathophysiology

Cardiovascular disease involves several different processes that contribute to the pathological mechanism, including hyperglycemia, inflammation, atherosclerosis, hypertension and more. Vasculature stability plays a critical role in the development of the disease. Discover the latest research on cardiovascular disease pathophysiology here.
