    Carotid intima media thickness is in a relation to risk factors for coronary artery disease

    Introduction: Carotid intima-media thickness (CIMT) is a double line pattern measured from the lumen-intima to media-adventitia interface. Measuring CIMT with B-mode ultrasound can detect early arterial wall changes. We aimed to measure CIMT in manifested atherosclerotic disease and find a relation to present risk factors. Material and methods: This cross sectional study included a population of 657 patients, with documented coronary artery disease (CAD), 66,1% were men (469 pts), 33,9% were women (241 pts). The mean age of patients was 64,72 years (55,6-73,8). The measurement of CIMT (maximal and mean) was performed with B-mode ultrasound, on longitudinal view, on multiple plaque-free segments at the level of common carotid artery, on the far wall, on both sides. Multivariate regression analysis was done to estimate independent factors for CIMT, when risk factors, age, and sex included in analysis. Results: The mean value of maximal CIMT was 0,96 mm (0,52-1,4), mean value of mean CIMT was 0,88 mm (range 0,61-1,15) and mean systolic blood pressure of 133,21 mm Hg (108,03-158,39) was found. Increased CIMT was found in 75,7% of patients (502 pts). Smoking was found as an independent risk factor for increased CIMT with odds ratio (OR) 4,7 (95% CI; 0,67-5,32) and diabetes mellitus with OR 1,6 (95% CI; 0,47-2,16). Conclusion: Diabetes and smoking are independently related to increased CIMT. These are preliminary results of National survey on 657 pts with coronary artery disease.

    OBJECTIVE: The aim of this study was to assess whether subclinical hypothyroidism (SCH) is associated with carotid atherosclerosis, as well as dyslipidemia, and arterial hypertension. SUBJECTS AND METHODS: The study included 69 consecutive patients with newly diagnosed SCH, and 30 matched healthy controls. Body mass index (BMI), TSH, fT4, antibodies to thyroid peroxidase (TPOabs), lipids, blood pressure, mean and maximum carotid intima-media thickness (CIMT) were determined in all participants. RESULTS: Mean values of CIMT, triglycerides, and total cholesterol/HDL-C ratio were significantly different in SCH patients versus matched controls. Linear multiple regression analysis demonstrated that TSH, diastolic blood pressure and triglycerides were independent predictors of mean CIMT, fT4 for maximum CIMT; and that TSH, fT4, age, and total cholesterol/HDL-C ratio were independent predictors of the presence of carotid plaques. CONCLUSION: Our data revealed that SCH is associated with increase in CIMT and presence of carotid plaques, independent of classical risk factors for atherosclerosis.
