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 使用二维超卢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)nlm和(28.88±3.06)mm.埘照男性和女性亚组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与对照男件和女性组间差异均有统计学意义(P值均＜0.01).多因素logistic同门分析显示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.

Objecfive 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 uhrasonography 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 cage history inquiring.physical examination,CT or MRI and ultrasonic examination.ResultsARD 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.
