Carotid Intima – Media Thickness and Plaque Can Predict The Occurrence of Ischemic Stroke
Journal Title: Journal of Medical Science And clinical Research - Year 2016, Vol 4, Issue 10
Abstract
B- mode ultrasound is a non-invasive method of examining the wall of the peripheral arteries And provides measures of the intima – media thickness (IMT) at various sites (common carotid artery, internal carotid artery), and plaques that may indicate early pre symptomatic diseases; therefore, estimating the intima-media thickness and plaque is important in term of evaluating patients with higher risk of cardiovascular and cerebrovascular disease. Objectives: We investigated whether carotid intima-media thickness and plaque measured by noninvasive B-mode Ultrasonography predicts ischemic stroke. Methods and Patients: This is a case - control study of patients admitted to hospital with diagnosis of ischemic CVA ; and patients without ischemic infarction; the diagnosis of cerebral infarction was confirmed by new CT of the brain. All participants underwent the standard examination and testing as well as carotid B-Mode ultrasound (Ultrasound measurements of right and left common carotid artery IMT and internal carotid artery IMT were made) and arteries were examined for plaques 1.5 cm a above and below the flow divider. Result: 52 patients were included in the study, 26 patients with ischemic stroke(case subjects) and 26 patients (control subjects).Mean maximum common carotid artery IMT , internal carotid artery IMT and the prevalence of plaque were significant higher in CVA group ( P < 0.05 , p= 0,001 , p <0.001 , respectively), other risk factors showed no significant difference between groups. Conclusion: The present study demonstrated increased maximum IMT of the common carotid artery, internal carotid artery. And Plaque in ICA are strong predictors for ischemic stroke.
