- BACKGROUND
Atherosclerosis is more prevalent in diabetic patients, severe and wide spread than in non-diabetic subjects and clinically evident as macrovascular diseases such as coronary, cerebro- vascular and peripheral arterial diseases which are important causes of frequent morbidity and premature mortality. But atherosclerotic vascular lesions are not easily detectable, before they advanced and cause symptoms. Measurement of carotid Intima-Media thickness(IMT) by high- resolution B-mode ultrasonography is a useful, non-invasive method to detect early atherosclerotic vascular changes. In this study, we investigated associations of IMT with cardiovascular risk factors. METHODS: High-resolution B-mode ultrasonography was performed in 63 non-insulin-dependent diabetic patients in order to determine maximal and mean carotid IMT. Blood pressure, glucose, HbA total cholesterol, HDL cholesterol and triglyceride levels were measured on a regular basis in the last 12 months before the carotid ultrasonography. The mean and last values at the time of the carotid ultrasonography were analyzed in relationship to the IMT. RESULTS: Carotid IMT was increased in NIDDM patients with male sex, smoking habit and hypertension. Systolic blood pressure (r=0.252, p=0.050) and LDL cholesterol levels (r=0.273, p=0.031) at the time of carotid ultrasonography showed a correlation with the IMT. Mean triglyceride (r=0.368, p=0.018) and HbA1c>, levels (r=0.288, p=0.045) of the last 12 months were correlated with the IMT. CONCLUSION: Increased carotid IMT was associated with male sex, smoking, hypertension, systolic blood pressure, LDL cholesterol, mean HbA, and triglyceride levels.

- BACKGROUND
Peripheral arterial disease (PAD) is one of the clinical manifestations of the atherosclerotic disease process. Early onset and rapid progression of PAD in diabetic patients has been well documented. PAD in diabetic patients has also been associated with an increased risk for total and cardiovascular mortality. Plethysmography is a noninvasive test to screen for the presence of PAD. Thus the aim of this study is to assess the risk factors for PAD screened by plethysmography in NII)DM patients. METHODS: A total of 289 NIDDM patients who undlerwent plethysmography were entered into our annlysis. Clinical characteristics of 38 patients with an ankle-brachial index of <0.9 (group B) were conapared with those of 231 patients with an ankle-brachial index of >1.0 (group A). RESULTS: Abnormalities in plethysmographic findings were found in 45.7% of diabetic patients. Age, duration of diabetes, hypertension, smoking, previous history of vascular diseases, HDL cholesterol, TC/HDL, and LDL/HDL appeared to be factors significantly related to PAD. Fasting sugar, HbAlc, total cholesterol, LDL cholestero1, trigly ceride, fibrinogen, lipoprotein(a), and waist-hip ratio were not significantly different between the two groups. The multiple logistic regression analysis showed the signficant contribution of the previous history of vascular disease (p=0.0028) and age (p-0.0115) to PAD in diabetic patients. CONCLUSION: The prevalence of PAD defined by plethysmography in our subjects was 45.7% higher than expected, suggests that efforts for early detection and prevention of PAD should be emphasized in diabetic patients.
