Assessment of aortic atherosclerosis and carotid atherosclerosis in coronary artery disease

The present study investigated the relationship between aortic atherosclerosis and carotid atherosclerosis, and studied the effects of coronary risk factors for these arteries. The subjects consisted of 78 patients with coronary artery disease (CAD) and 69 patients without CAD. All subjects underwent enhanced computed tomography and B-mode ultrasonography within a short time period to determine the extent of aorta and carotid atherosclerosis. Significant correlations between maximal aortic wall thickness (MAWT) and aortic wall volume (AWV) with carotid intima-media thickness (IMT) were demonstrated. MAWT, AWV and IMT were significantly higher in patients with CAD compared with controls (p=0.009, p=0.024, p=0.001, respectively). Furthermore, there were significant differences in MAWT, AWV and IMT among groups classified by the number of coronary artery stenoses, and no significant differences among groups classified by risk factors, but it was shown that MAWT, AWV and IMT increased gradually as the risk factors increased in number. MAWT, AWV and IMT had positive correlations with age, systolic blood pressure and triglyceride, and a negative correlation with high density lipoprotein-cholesterol. This study demonstrated that both aortic atherosclerosis and carotid atherosclerosis are closely correlated with coronary atherosclerosis, and that the atherosclerosis indices are independently associated with age and hyperlipidemia.     

Progression of carotid atherosclerosis in Japanese patients with coronary artery disease

The authors investigated the relationship between the progression of carotid atherosclerosis and the severity of coronary artery disease (CAD). The two-year follow-ups of extracranial carotid atherosclerosis in 50 patients with CAD were evaluated by B-mode high-resolution ultrasonography. The summed maximal thickness of carotid plaques increased by 3.2 to 10.1 mm (mean 1.06 mm, SD 2.42 mm). The extent of coronary atherosclerosis (p<0.02) and the serum total cholesterol level (p<0.01) were different between the progressing group (n=20) and the nonprogressing group (n=25) with carotid atherosclerosis. Carotid disease progression was significantly higher in patients with three-vessel coronary disease than in those without significant coronary disease (p<0.005). Age, serum triglyceride, high-density lipoprotein-cholesterol, pack-years of smoking, % smokers, % hypertensives, and % diabetics were not different between the two groups. It was concluded that the severity of CAD was one of the strong predictors for carotid disease progression in patients with CAD.

Ultrasonic correlates of common carotid atherosclerosis in patients with coronary artery disease

Increased intima-media thickness and plaque development in the extracranial carotid arteries reportedly correlate well with the prevalence of coronary artery diseases. The location of these atherosclerotic lesions in the carotid artery varies with age in patients with coronary artery atherosclerosis. Intima-media thickness, plaque, and calcification in the common carotid artery and bifurcation were assessed with high-resolution B-mode ultrasonography. Forty patients with severe atherosclerosis of the coronary artery and 56 healthy control subjects with no risk factors for coronary atherosclerosis were included in this study. The subjects were divided into a middle-age group (40-59 yr) and an old-age group (60-79 yr). In both groups, the intimamedia thickness in the patients was significantly higher than that in the controls. Intima-media thickness of at least 0.7 mm in the middle-age group and at least 1.0 mm in the old-age group was specific and positively predictive of coronary artery disease. Plaque (> 1.0 mm) and calcification were more significant in patients than in controls. In the middle-age group, intimamedia thickness in the common carotid artery was correlated with coronary atherosclerotic severity. Conversely, in the old-age group, the presence of plaque and calcification at the bifurcation was correlated with coronary atherosclerotic severity. The characteristic manifestation of the atherosclerotic lesion in the carotid artery varied with age in patients with coronary artery disease.
