Abstract
Carotid artery atherosclerosis, age, family history, smoking, arterial hypertension, diabetes mellitus, and dyslipidemia represent riskfactors of cerebrovascular events (stroke and transient ischemic attack). Hence, preventive treatment is vital for patients presentingthese factors. Seven hundred and sixty-six patients (348 men and 418 women; age range 30-80 years) who were asymptomatic andattending a vascular unit for routine ultrasound (US) screening of the carotid arteries and with risk factors, intima-media thickness (IMT)of carotid artery > 1.3 mm, IMT associated with findings of atherosclerotic plaque creating stenosis > 20%, < or = 50%, and carotidplaque creating stenosis > 50% were considered. For patients with diabetes and hyperlipemia (35.8%)--or with hypertension, diabetes,and hyperlipemia (34.8%)--a higher prevalence of IMT > 1.3 mm was found. Higher prevalence of atherosclerotic plaque > 50% variedbetween 14.2% (in cases with diabetes mellitus and dyslipidemia) and 29.6% (in cases presenting 4 concomitant risk factors). Directcorrelation was found between different risk factors and US findings. Our US findings revealed both a high incidence of carotidatherosclerosis, and that single and multiple correlation between US diagnosis of vascular damage and risk factors further enhancedrisk. The study results confirmed the significance of vascular risk factors in patients with carotid artery atherosclerosis, and underlinedthe diagnostic validity of US.File | Dimensione | Formato | |
