[A study on the relationship between metabolic syndrome and anterior cerebral infarction].

OBJECTIVE: To study the relationship between metabolic syndrome (MS) and anterior circulation infarction (ACI). METHODS: 271 ACI patients (166 men and 105 women) who fulfilled the diagnostic criteria of China Guideline for Cerebrovascular Disease Prevention and Treatment were enrolled. 147 control subjects (67 men and 80 women) without the clinical signs of cerebral infarction but with detailed case history, physical examination and CT or MRI were also selected. The prevalence and risk of MS were observed in the ACI and control group. MS was defined with the modified criteria in Chinese. RESULTS: The prevalence of MS in the ACI group and control subjects was respectively 43.17% and 19.05%. The prevalence of MS was significantly higher in the ACI group as compared with the control subjects (P < 0.01). The component level of MS were significantly different between the two groups (P < 0.05). MS was associated with a 3.7 fold higher risk of ACI (P < 0.01). CONCLUSIONS: There is a close relationship between MS and ACI. MS is an important risk factor of ACI.

[Analysis of the changes in aortic root dimension in patients with anterior cerebral infarction].

OBJECTIVE: To analyze the relationship between aortic root dimension (ARD) and anterior circulation infarction (ACI) by measuring ARD of ACI patients. METHODS: The ARD of 110 ACI patients (56 men and 54 women) were measured with 2-dimensional ultrasonography during ventricular systole. 66 control subjects (32 men and 34 women) without the clinical signs of cerebral infarction or organic heart disease and cardiac insufficiency were selected after carrying out detailed case history inquiring, physical examination, CT or MRI and ultrasonic examination. RESULTS: ARD in men and women was respectively (29.80 +/- 2.35) mm and (28.88 +/- 3.06) mm in the ACI group. While it was (27.64 +/- 1.70) mm and (26.98 +/- 1.60) mm respectively in the control subjects. ARD in men and women was significantly higher in the ACI group as compared with the control subjects (P < 0.01). Logistic regression analysis indicated that the odds ratio (confidence interval) associated with ARD was 1.630 (1.205 - 2.204) in men and 1.494 (1.098 - 2.033) in women for ACI. CONCLUSIONS: There is a close relationship between ARD and ACI. ARD is an important risk factor of ACI.
