Study hypothesis
Patients with chronic kidney disease (CKD) mainly die from cardiovascular-related causes, with a mortality 20 times the risk of a general population. Although all the traditional risk factors are accountable, studies show that oxidative stress makes a particular contribution to the excessive cardiovascular risks. Oxidative stress promotes left ventricular hypertrophy (LVH) and causes endothelial dysfunction. LVH is known to be an independent predictor of cardiovascular events and studies have shown the survival benefits of regressing LVH. Allopurinol has been proven to be a potent antioxidant. Hence, this study looks to see if allopurinol would regress LVH and also improve endothelial dysfunction in patients with CKD.
