Non-traditional markers of atherosclerosis potentiate the risk of coronary heart disease in patients with type 2 diabetes and metabolic syndrome.Nutr Metab Cardiovasc Dis 2008; 18(1):31-8NM
BACKGROUND AND AIMS
The aims of this study were to establish the prevalence of metabolic syndrome (MS), in type 2 diabetes mellitus (DM), according to National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III) criteria, and to assess the association of MS with other cardiovascular (CV) risk factors in these patients.
METHODS AND RESULTS
A cross-sectional study was conducted in 1610 patients with type 2 DM. Glycated hemoglobin A1c (HbA1c), total cholesterol, low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C), uric acid, fibrinogen, creatinine, and albumin/creatinine ratios were measured. The risk of coronary heart disease (CHD) was calculated using the UKPDS Risk Engine. Seventy percent of the diabetic population met the criteria for MS; central obesity and hypertension were the most common criteria. Subjects with MS had higher levels of HbA1c, LDL-C, non-HDL-C, uric acid, and fibrinogen compared to patients without MS. Similarly, microalbuminuria and a high triglyceride (Tg)/HDL-C ratio (a marker of small LDL-C) occurred more frequently in patients with MS. When patients with no history of CHD events were considered, mean CHD risk was greater in those with, than those without, MS.
MS is highly prevalent in type 2 DM and is commonly associated with non-traditional CV risk factors. The diagnosis of MS seems to confer additional CHD risk in patients with type 2 diabetes.
