前循环脑梗死患者主动脉根部宽度变化及分析

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

目的通过观察前循环脑梗死患者主动脉根部宽度（ARD）变化，分析ARD与前循环脑梗死的关系。方法使用二维超声在心室收缩期测量主动脉根部内径宽度，测量前循环脑梗死患者110例。结果前循环脑梗死患者男性和女性亚组ARD分别为（29．80±2．35）mm和（28．88±3．06）mm。对照男性和女性亚组ARD分别为（27．64±1．70）mm和（26．98±1．60）mm。前循环脑梗死患者男性和女性组ARD与对照男性和女性组间差异均有统计学意义（P值均〈0．01）。多因素logistic回归分析显示ARD是男女前循环脑梗死发病的独立危险因素（P值均〈0．01）。结论ARD与前循环脑梗死关系密切，ARD是前循环脑梗死的重要危险因素。

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.
