颈动脉粥样硬化与冠心病的关系

Carotid atherosclerosis and coronary disease relations

目的探讨颈动脉粥样硬化与冠心病的关系。方法本文通过对60例因心绞痛、心肌梗死及胸痛待查而入院的患者行冠状动脉造影检查,并与造影前后一周内对上述患者行颈动脉血管彩色多普勒超声检查,根据造影结果分为冠心病单支病变组、多支病变组和正常组(对照组),比较各组间所测得的颈动脉血管后壁内中膜厚度(IMT)及斑块发生率。结果随着冠状动脉病变严重程度的增加,IMT值和斑块发生率随之增高。结论颈动脉粥样硬化与冠心病之间关系密切,较早行颈动脉超声的检查可以预测冠状动脉的病变程度。

Objective To explore the relationship between carotid atherosclerosis and coronary disease. Methods According to the result of coronary arteriography there were 60 patients with angina pectoris, myocardia infarction or pectoralgia of unknown cause who were divided into 3 groups ： normal group, mono-coronary （pathologic change） group and muhi-coronary group, around in a week the intima-mediathickness（IMT） of cartid artery were examined by colored Doppler before or after arteriography in all patients, and the inspected-results of IMT in 3 groups were compared with one another. Results The results of colored Doppler ultraaonic examination showed the chang of IMT value and athermatous plaque rate in carotid artery, increasing with serious degree of coronary pathologic change. Conclusion Carotid atheroselerosis is closely correlated with coronary pathologic change, so the measurement of IMT value of earotid artery is a method for forecasting the coronary disease.
