Cardio-ankle Vascular Index (CAVI) in Hypertension Patients After One Year of Treatment

Study Overview
=================
Brief Summary
-----------------
This study aimed to evaluate the role of the cardio-ankle vascular index (CAVI) in evaluating arterial stiffness changes, the degree of atherosclerosis in patients with hypertension after 1 year of treatment and analysis the correlation between CAVI and cardiovascular risk factors.
