Background: To assess the effect of the atherosclerotic cardiovascular disease risk enhancing factors (ASCVD-REFs) on incident cardiovascular disease (CVD) events among non-diabetic individuals with borderline and intermediate ACC/AHA score during 10 and 15-year follow-up. Moreover, the added value of these ASCVD-REFs on the predictive power of the pooled cohort equations (PCE) was examined. Methods: A total of 1204 adults aged 40-75 years, free from CVD at baseline with low-density lipoprotein cholesterol (LDL-C) between 70-189 mg/dl, were included. Unadjusted Cox regression analysis was used. The predictive ability of each significant ASCVD-REFs was estimated using the cut-point-free integrated discrimination improvement (IDI).Results: During 10-year follow up, 181 CVD events (including 73 hard CVD) occurred. For hard CVD events, the high blood pressure (BP) component (i.e. ≥130/85 mmHg) of metabolic syndrome (Mets) (Hazard ratio: HR (95% CI; 1.67(1.03-2.70)) and positive history of preeclampsia (5.06(1.17-22.0)) were significant ASCVD-REFs. During the longer follow-up, Mets and its components of high waist circumference (WC) and high BP significantly increased the risk. As for CVD events, the Mets and its high BP and high WC components significantly increased the risk. However, in the ACC/AHA adjusted score, these covariates did not significantly improve the predictive power of the CVD or hard CVD. Conclusions: The high BP was the most consistent and independent ASCVD-REFs in the prediction of all CVD and hard CVD, among the population with borderline/intermediate risk. Hence, considering pharmacologic therapies for patients with high BP and high LDL-C might be beneficial for preventive initiatives.
