AIM:To evaluate if the intima-media thickening (IMT) and asymptomatic carotid plaque (ACP), as expression of carotid preclinical atherosclerosis (pre-ATS), can provide further information on the global cardiovascular risk (GCVR).METHODS:We studied 454 asymptomatic subjects, with a cluster of risk factors (RF), and evaluated the incidence of a first cardiovascular (CV) event in a five-year follow-up. The subjects at admission were subdivided in three groups of risk.RESULTS:Events occurred in 38% of subjects at high risk, in 13% and 6% of subjects at intermediate and low risk (p<0.003). Among evaluated parameters, carotid pre-ATS was a predictive marker of CV events (OR 2.7, 95% IC 1.4-5.1, p<0.0024). In subjects with GCVR<20% the prevalence of events was 8% for normal carotid ultrasound findings, 13% for increased IMT and 15% for ACP.CONCLUSIONS:In primary prevention, the IMT measurement can give further information for a better stratification of GCVR. The pre-ATS of carotid arteries should be considered a strong predictor of future CV events and should suggest a more aggressive treatment of RF.
