Abstract

Background and Purpose: The purpose of this study was to evaluate the effect of metabolic syndrome on ischemic stroke in Chinese subjects with type 2 diabetes. Methods: Anthropometric parameters (waist circumference and body mass index), blood pressure, and plasma biochemical (lipid and glycemic profiles) were collected. Subjects with type 2 diabetes were categorized by the criteria of the updated Adult Treatment Panel III (ATP III) with the modified definitions of obesity in Asians. Transcranial Doppler was performed to define middle cerebral artery stenosis. Results: Of 2,197 patients (age 55.4 +/- 11.3 years; male 40.8%; median follow-up period 8.7 years, interquartile range 7.8-9.5 years) without symptoms of cerebrovascular disease, evidence of middle cerebral artery stenosis was identified in 272 subjects (12.4%). According to NCEP ATP III criteria, 1,324 (60.3%) patients had MetS at baseline. Ischemic stroke occurred in 184 (8.4%, 184/2197) patients during follow-up. Patients with incident stroke had a higher prevalence of MetS compared with those without stroke (p = 0.004), and the number of components of MetS was also significantly increased in patients with stroke (p = 0.001). Cox regression demonstrated that MetS was not associated with incident stroke. Conclusions: In Chinese type 2 diabetic patients, metabolic syndrome does affect stroke occurrence with a higher stroke incidence among those with metabolic syndrome, but stroke occurrence seems to be better explained by other vascular risk factors than by metabolic syndrome.
