Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study is intended to investigate the effect of angiotensin receptor blockers (ARBs) on mild-to-moderate aortic stenosis.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Studies support the concept that activation of the renin-angiotensin system may be involved in the progression of valve stenosis and myocardial fibrosis in aortic stenosis. Furthermore recent studies have shown that renin-angiotensin system medication may slow down aortic stenosis progression rate and left ventricle remodeling.

Thus the present study is a randomized control trial to test the efficacy of the angiotensin receptor blocker (ARB) to slow down aortic stenosis progression and left ventricular remodeling/dysfunction in patients with mild-to-moderate aortic stenosis.
