Cardio-ankle vascular index represents the best surrogate for 10-year ASCVD risk estimation in patients with primary hypertension.

: Identification of target organ damage and/or risk-enhancing factors help treatment decisions in hypertensive and hyperlipidaemic patients who reside in borderline to an intermediate risk category based on 10-year atherosclerotic cardiovascular disease (ASCVD) risk estimates.: In the present study, we aimed to investigate the comparative efficacy of certain hypertension-mediated organ damage markers (HMOD) for the prediction of 10-year ASCVD risk ≥10%, in patients with primary hypertension without established CVD.: One-hundred thirty-seven asymptomatic hypertensive patients ≥40 years of age were enrolled in the present study. Ten-year ASCVD risks were estimated by Pooled Cohort Equations. The following HMOD markers; pulse pressure (PP), left ventricular mass index (LVMI), carotid intima-media thickness (CIMT), ankle-brachial index (ABI), cardio-ankle vascular index (CAVI) and estimated glomerular filtration rate (eGFR) were evaluated with respect to efficacy for predicting ≥10% ASCVD risk with ROC analysis.: CAVI gave the greatest Area Under Curve (AUC = 0.736, < .000), and followed by CIMT (AUC = 0.727, < .000), LVMI (AUC = O.630, = .01), and PP (AUC = 0.623, = .02). ABI and eGFR were not found to be predictive. CAVI correlated best with estimated 10-year ASCVD risk ( = 0.460, < .000). A CAVI value ≥8 was found 71% sensitive and 72% specific for predicting ≥10% risk in 10-year ASCVD risk scale. CAVI gave the best graded response to increments in 10-year ASCVD risk categories.: We suggest that CAVI is the best surrogate for 10-year ASCVD risk, among several HMOD markers.
