ABSTRACT
PURPOSE:
To investigate the prevalence and risk factors of atherosclerotic disease of the extracranial carotid artery in healthy Korean population.METHODS:
Eight hundred twenty-five patients without previous history of transient ischemic attack, amaurosis fugax, and/or any neurologic deficit who underwent carotid artery ultrasonography were evaluated retrospectively. The patients were divided into five groups according to the degree of carotid artery stenosis using real-time B-mode high resolution ultrasonography; Group A-normal carotid artery, Group B-below 30% of carotid artery stenosis, Group C-from 31% to 50% of carotid artery stenosis, Group D-from 51% to 70% of carotid artery stenosis, Group E-above 71% of carotid artery stenosis. Medical Records of all patients were investigated for following factors; sex, age, family history, smoking, hypertension, diabetes mellitus, total cholesterol, HDL- cholesterol, LDL-cholesterol, TG (triglyceride), HbA-1c (hemoglobin A-1c), and folate.RESULTS:
12.5% of asymptomatic patients have carotid stenosis due to atherosclerosis of extracranial carotid artery. The prevalence of extracranial carotid artery stenosis was as follows; Group B 2.2%, Group C 7.0%, Group D 3.0%. The age, total cholesterol, LDL-cholesterol and HbA-1c were significantly higher in Group B, C, D than Group A (P=0.001, 0.016, 0.011, 0.001). The prevalence of diabetes and hypertension were significantly higher in Group B, C, D than Group A. Other factors, however, were not different among the groups.CONCLUSION:
Asymptomatic carotid artherosclerosis is not uncommon in Korea. Carotid ultrasonography would be necessary for patients with hypertension, diabetes, and high serum cholesterol level.
