About

Hypertension is highly prevalent in hemodialysis (HD) patients and leads to increased morbidity and mortality due to cardiovascular disease(CVD). Left ventricular hypertrophy (LVH) is both a manifestation of hypertension caused end-organ damage and an independent risk factor for CVD. Evidence shows that Beta-blockers, especially of low dialyzability decrease risk of CVD and mortality. Calcium channel blockers (CCBs) were also shown to effectively control BP in the volume expanded state and reduce cardiovascular disease risk. Asymmetric dimethyl arginine (ADMA) is a uremic toxin that decreases NO synthesis and is correlated to LVH, carotid intimal thickness (CIT), CVD, and mortality. Amlodipine is shown in one study to significantly reduce ADMA level in HD patients. The purpose of this study is to determine the effect of calcium channel blocker Amlodipine compared to Beta-blocker Bisoprolol on regression of LVH, reduction of ADMA plasma level and on BP control among hypertensive patients on HD.
