Changes in Central Aortic Pressure, Endothelial Function and Biomarkers in African Americans With Cardiometabolic Syndrome: Comparison of Amlodipine/Olmesartan Versus Hydrochlorothiazide/Losartan

The purpose of the study is to compare the effects of Azor (a combination of amlodipine and olmesartan) with Hyzaar ( a combination of losartan and hydrochlorothiazide) on the thin lining on the inside of blood vessels. These cells help keep blood vessels healthy and blood pressure normal.
