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