ABSTRACT
BACKGROUND AND OBJECTIVES:
Carotid artery intima-media thickness (CIMT) has recently been recommended as a non-invasive tool for primary prevention of cardiovascular events; the association between CIMT and adverse cardiovascular events is well-known. We sought to evaluate the prevalence and significance of carotid artery plaque, especially in patients with coronary atherosclerosis. SUBJECTS ANDMETHODS:
The study population consisted of 1,705 consecutive patients {933 males (54.7%); mean age, 59.7+/-10.9 years} who underwent coronary angiography and carotid artery scanning using high-resolution ultrasonography. Carotid plaque was defined as a focal structure encroaching into the arterial lumen by at least 50% of the surrounding IMT value or a thickness >1.2 mm.RESULTS:
Carotid plaque was identified in 30.3% (516/1,705) of the patients. Of patients in whom the plaque location could be evaluated (n=1,027), carotid plaque was located at the common carotid artery {n=64/267 (24.0%)}, carotid bulb {n=194/267 (72.7%)}, and at both sites {n=9/267 (3.4%)}. The prevalence of hypertension (58.5% vs. 45.2%, p or =65 years), hypertension, and increased CIMT (> or =1.0 mm) were independent predictors of carotid plaque. Carotid plaque (odds ratio, 1.85; 95% confidence interval, 1.39-2.45; p<0.001) was an independent predictor of multivessel disease based on multivariate regression analysis.CONCLUSION:
Carotid plaque was common (30.3%) in Korean patients with coronary atherosclerosis, but it is still relatively uncommon compared to Western populations. Carotid plaque was associated with old age, hypertension, and increased IMT, and was an independent predictor of multi-vessel disease.
