BACKGROUND AND PURPOSE Metabolic syndrome (MetS) is associated with an increased risk of the subsequent development of cardiovascular disease or stroke. Moreover, a silent brain infarction (SBI) can predict clinical overt stroke or dementia. We examined the associations between SBI and MetS in apparently healthy individuals. METHODS We evaluated 1588 neurologically healthy subjects (927 males and 661 females) who underwent brain MRI at Seoul National University Hospital Healthcare System Gangnam Center. MetS was defined using the criteria of the National Cholesterol Education Program Adult Treatment Panel III. We examined associations between full syndrome (> or =3 of the 5 conditions) as well as its components and SBI by controlling possible confounders. RESULTS Eighty-eight (5.5%) were found to have > or =1 SBI on MRI. Age was found to be significantly related to SBI prevalence (odds ratio [OR], 1.06; 95% CI, 1.04 to 1.09). A history of coronary artery disease was associated with an elevated odds ratio of SBI (OR, 2.83; 95% CI, 1.38 to 5.82), and MetS was significantly associated with SBI (OR, 2.18; 95% CI, 1.38 to 3.44). The components model of MetS showed a strong significance between an elevated blood pressure (OR, 3.75; 95% CI, 2.05 to 6.85) and an impaired fasting glucose (OR, 1.74; 95% CI, 1.08 to 2.80) and the risk of SBI. CONCLUSIONS MetS was found to be significantly associated with SBI. This finding has clinical utility in terms of identifying healthy people at increased risk of developing SBI.

Silent subcortical brain infarction

Introduction: The silent brain lesions detected by MRI were fairly common not only in first-ever stroke but also in normal elderly subjects. Some recent studies show the possible role of silent sub-cortical brain infarction in ischemic stroke. The aim of this study was to evaluate the frequency of silent sub-cortical brain infarction in acute first-ever ischemic stroke. Methods: In this descrip...

Metabolic syndrome is associated with silent ischemic brain lesions.

BACKGROUND AND PURPOSE Metabolic syndrome (MetS) is a recognized risk factor for stroke, but it is unclear whether MetS is also related to subclinical ischemic lesions. We examined the association of MetS with the prevalence of silent brain infarction, periventricular hyperintensity, and subcortical white matter lesions in healthy adults. METHODS We conducted a cross-sectional study in 1151 J...

Comparison of Serum Level and IL-18 Gene Expression and Reactive Protein in Patients with Type 2 Diabetes with Metabolic Syndrome and Healthy People

Introduction: Metabolic syndrome is a common clinical anomaly, with an increased risk of developing type 2 diabetes and cardiovascular risk factors. Increased inflammatory mediators, such as reactive protein,as well as the inflammatory cytokines can be associated with the incidence and progression of metaboli syndrome and type 2 diabetes.   Materials & Methods: This study was performed on 35 m...

Silent Brain Infarcts (SBI) are associated with an increased risk of subsequent stroke. SBI are incidentally revealed by CT or MRI executed in stroke patients. A prospective study was undertaken involving 200 consecutive patients aged >45 years with brain infarct admitted in University of Alberta Hospital, Canada (100 patients) and Valie-Asr Hospital, Iran (100 patients) in 2003. Patients w...

Elevated white blood cell counts and risk of metabolic syndrome: a dose-response meta-analysis

Background and Aim: Elevated white blood cell count has been a known risk factor for cardiovascular diseases. Cardiometabolic diseases have some risk factors in common. Therefore, we assessed the association between elevated white blood cell counts and risk of metabolic syndrome using dose-response meta-analysis method. Materials & Methods: We searched for observational studies including white ...
