Abstract

PURPOSE:

The association of ischemic stroke and metabolic syndrome (MetSyn) with or without diabetes mellitus (DM) is not clear. The present study aimed to identify the impact of diabetes or hyperglycemia on the risk of MetSyn-associated ischemic stroke.

MATERIALS AND METHODS:

This study comprised an Asian population of 576 patients with acute nonembolic cerebral infarction and 500 controls. MetSyn was defined according to the criteria of the International Diabetes Federation. MetSyn patients were further subgrouped according to their glucose levels: MetSyn with DM, MetSyn with impaired fasting glucose (IFG) and MetSyn with normal glucose tolerance (NGT). The impact of MetSyn on cerebral infarction was then evaluated.

RESULTS:

At baseline, the prevalence of MetSyn in patients with cerebral infarction was higher than that of the controls (57.29% vs. 10.00%, p<0.01). In the stroke group, the prevalences of MetSyn with DM, IFG, and NGT were 25.69%, 8.85% and 22.74%, respectively, all of which were higher than that of the controls (all p-values<0.05). By multiple logistic regression analysis, we discovered that MetSyn was associated with an increased risk of cerebral infarction (odds ratio: 5.73, p<0.01). After adjustment for all the components of MetSyn, the odds ratios of MetSyn with DM, IFG, and NGT were 5.70, 2.24 and 2.19 (all p-values <0.05), respectively.

CONCLUSION:

In Asian population, patients with MetSyn accompanied by T2DM are at the greatest risk for acute non-embolic stroke. Additionally, IFG was not observed to be associated with an increased risk for MetSyn-related ischemic stroke.
