BACKGROUND AND OBJECTIVES: Increased carotid intima-media thickness (IMT) is known to be associated with adverse cardiovascular events in the patients with risk factors or established atherosclerosis. However, the prognostic importance of carotid IMT is uncertain in the patients who underwent percutaneous coronary intervention (PCI). We sought to evaluate the association of carotid IMT with major adverse cardiovascular events (MACE) and restenosis in the patients who underwent PCI. SUBJECTS AND METHODS: The study population consisted of 308 consecutive patients who underwent PCI, and they were followed up for mean of 30.6+/-13.3 months. Base on the median values of carotid IMT, which was measured in the right common carotid artery at the time of PCI with using high-resolution ultrasound and a semiautomatic method, the subjects were divided into the thick (n=156, 1.003+/-0.14 mm) and thin IMT (n=152, 0.748+/-0.07 mm) groups, and they were followed up for at least 1 year. RESULTS: Patients with thick carotid IMT were older (61+/-9 years vs. 57+/-10 years, respectively, p=0.001), had a higher body mass index (25.0+/-3.0 vs. 23.9+/-4.0, respectively, p=0.017), a history of previous myocardial infarction (20% vs. 9%, respectively, p=0.008), more multivessel disease and more restenosis (34.6% vs. 23.0%, respectively, p=0.025) than those patients with a thin carotid IMT. However other MACEs such as death, myocardial infarction, stroke, heart failure and target lesion revascularization did not show any significant differences between the two groups. Multivariate Cox regression analysis showed that carotid IMT was an independent predictor of restenosis (odds ratio: 1.754, 95% confidence interval: 1.1296 to 2.726, p=0.012). CONCLUSION: An increased carotid IMT is associated with restenosis, but it does not have clinical prognostic importance for the patients who underwent PCI during a mean follow up period of 31 months.

BACKGROUNDS/AIMS: It has been suggested that there is a differential response of the vasculature to systemic risk factors for atherosclerosis. We sought to evaluate the impact of hypertension on the carotid arterial wall using new methods that can measure each arterial wall layer. METHODS: The study subjects consisted of 163 patients who underwent carotid arterial scanning using high-resolution ultrasound that could measure the left carotid intima-media, intima, and media separately. The individual carotid arterial wall thickness was measured off-line by a new method using the Canny edge-detection algorithm. RESULTS: Hypertensive patients (n=79, mean age 61.8 years) had a higher prevalence of diabetes (31.6% vs 11.9%, p=0.004) and a lower level of HDL-cholesterol than did normotensive patients (41.8+/-11.0 mg/dL vs 45.7+/-10.0 mg/dL, p=0.019). Hypertensive patients had higher carotid intima-media thickness (CIMT, 0.81+/-0.21 mm vs 0.74+/-0.18 mm, p=0.003) and carotid medial thickness (CMT, 0.46+/-0.12 mm vs 0.42+/-0.09 mm, p=0.007) than did normotensive patients, whereas carotid intimal thickness (CIT) was not significantly different (0.34+/-0.04 mm vs 0.34+/-0.04 mm, p=0.196). Multivariate analysis revealed that the independent factors of CIMT were CMT (beta=0.915, p<0.001), hypertension (beta=0.076, p=0.008), age (beta=0.074, p=0.010), and sex (beta=-0.079, p=0.005). Pearson correlation coefficient between CIMT and CMT was higher (r=0.932, p<0.001 vs r=0.445, p<0.001) than that between CIMT and CIT. The correlation between CIMT and CMT was higher (r=0.940, p<0.001 vs r=0.910, p<0.001) in hypertensive patients than in normotensive patients, whereas that between CIMT and CIT was lower (r=0.344, p=0.002 vs r=0.583, p<0.001) in hypertensive patients. CONCLUSIONS: The increased CIMT is caused by increased CMT in hypertensive patients, and this finding is compatible with the medial hypertrophy seen in hypertension. The carotid medial layer should be the focus of attention in future studies looking at hypertensive patients.

BACKGROUND AND OBJECTIVES: A prolonged heart rate-corrected QT interval (QTc) is known to be related to an increased risk of coronary artery disease (CAD) and sudden cardiac death, while the carotid intima-media thickness (IMT) is related to CAD. We sought to evaluate the relationship among the QTc, the carotid IMT and the severity of CAD. SUBJECTS AND METHODS: The QTc and the carotid IMT were measured in 165 consecutive patients who underwent coronary angiography. The measurement of the QTc was done automatically by a digital QT GuardTM system (GE Marquette Medical System, Milwaukee, USA) and the carotid IMT was measured by M'ATH software (METRIS Co., Argenteuil, France). The severity of CAD was divided into minimal disease (90, 54.5%), one-vessel disease (32, 19.4%), and multi-vessel disease (43, 26.1%), according to the number of vessels that were narrowed by more than 50%. RESULTS: The mean values of the QTc were 415.1+/-20.5 msec in the minimal disease group, 411.7+/-17.0 msec in the one-vessel disease group and 434.2+/-46.1 msec in the multi-vessel disease group. The QTc was correlated with age (r=0.236, p=0.002), HDL cholesterol (r=-0.160, p=.043), the right carotid IMT (r=0.17, p=0.026), the left carotid IMT (r=0.178, p=0.022) and the severity of CAD (r=0.243, p=0.002). On the multiple linear regression analysis after adjustment for age and HDL cholesterol, the QTc was an independent factor for the severity of CAD. CONCLUSION: These results suggest that repolarization abnormalities are associated with the severity of CAD and they may reflect the severity of the morphologic atherosclerotic surrogates.

BACKGROUND AND OBJECTIVES: It's not clear whether the serum lipid level is associated with the individual carotid arterial wall thickness for patients suffering with coronary atherosclerosis, although hypercholesterolemia is associated with an increased carotid IMT. We sought to evaluate the association between the serum lipid level and the individual carotid arterial wall thickness (intimal thickness (IT) and medial thickness (MT)) as well as the carotid intima-media thickness (IMT) for patients with coronary atherosclerosis. SUBJECTS AND METHODS: The carotid arterial wall thickness was measured using high-resolution B-mode ultrasound in 139 consecutive patients (58+/-11 years old, 75 males) with coronary atherosclerosis by performing coronary angiography. RESULTS: Measurement of the individual arterial wall thickness was possible in 126 patients (90.6%) out of all the study subjects. The carotid IMT was correlated with the total cholesterol (r=0.207, p=0.015) and low-density lipoprotein (LDL) cholesterol (r=0.237, p=0.006). The carotid IT was correlated with the total cholesterol (r=0.210, p=0.020), triglyceride (r=0.212, p=0.018), and LDL-cholesterol (r=0.246, p=0.006), whereas the MT did not show any significant correlation with the serum lipid level. Multivariate analysis disclosed that the serum LDL cholesterol level was associated with the carotid IMT and IT for the patients with coronary atherosclerosis, but it was not correlated with the MT. CONCLUSION: This study suggests that the serum LDL cholesterol level is more closely associated with the carotid IT than the IMT for patients with coronary atherosclerosis, and each carotid arterial wall has a different response to the serum lipid level.

BACKGROUND AND OBJECTIVES: While the clinical significance of descending thoracic aorta intima-media thickness (DTA-IMT) remains unclear, common carotid IMT (CIMT) is known to be associated with major adverse cardiovascular events (MACE) in patients with atherosclerotic disease. SUBJECTS AND METHODS: A total of 104 patients (mean age, 59 yrs; 69 male) with angiographically proven coronary atherosclerosis underwent transesophageal echocardiography (TEE) for DTA-IMT measurement and carotid scanning for CIMT measurement. The patients were divided into two groups based on the median IMT value, and they were followed up for cardiovascular events and all-cause mortality for a period of 50+/-21 months. RESULTS: Patients having a higher DTA-IMT value (n=44, >2.1 mm) had a higher chance of stroke (6.7% vs. 2.8%, p=0.04), peripheral vascular disease (6.7% vs. 1.9%, p=0.02), and death (2.9% vs. 0%, p=0.04) than those who had lower DTA-IMT values (n=60, < or =2.1 mm). The patients who had higher CIMT values (n=49, >0.089 mm) had a higher chance of peripheral vascular disease (16% vs 2%, p=0.009) than those having lower IMT values (n=55, < or =0.089 mm). However, there was no significant difference between the groups in terms of recurrent chest pain, heart failure, syncope, myocardial infarction or chronic kidney disease during the follow-up period. Multivariate Cox regression analysis revealed that increased DTA-IMT was associated with stroke (OR, 4.29; 95% CI, 1.076-17.181; p=0.039) and peripheral vascular disease (OR, 9.37; 95% CI, 1.571-55.499; p=0.014), whereas increased CIMT was associated with peripheral vascular disease (OR, 14.365; 95% CI, 1.050-196.540; p=0.046). CONCLUSION: This study suggests that descending thoracic aorta IMT is more closely associated with prognosis in patients with coronary atherosclerosis than CIMT.
