超声评价颈动脉内中膜厚度及粥样斑块与冠心病的关系

Relationship between carotid intima-media thickness and plaque and coronary artery disease with ultrasonography

目的探讨冠心病与颈动脉硬化的关系。方法对80例行冠脉造影的患者行双侧颈动脉超声检查,观察颈动脉内壁光滑程度、内-中膜厚度和有无动脉硬化斑块,根据冠脉造影的结果分为冠心病组和非冠心病组,并将两组结果进行对比分析。结果45例冠心病患者中,32例有不同程度的颈动脉斑块形成,发生率71.1%;非冠心病组35例中有10例(28.6%),两组间有统计学差异(P<0.05)。结论颈动脉粥样硬化与冠心病有密切的相关性。超声检查能早期发现颈动脉粥样硬化,对有效预防冠心病的发生有重要意义。

Objective To evaluate the relationship between coronary artery disease and intima-media thickness and plaque of the carotid artery with ultrasonography. Method 80 patients were detected with coronary angiography （CAG）. Te carotid arteries intima-midia thickness or plaque were examined by ultrasonography. The subjects were divided into two groups, including normal group and CAHD group, by CAG. Results Among 45 cases from, there were 32 cases （71.1%） and 10 cases （28. 6%） with carotid plaque in CAHD group （45 cases） and normal group （10 cases）, respectively. Conclusion IMT and plaque of the common carotid artery are related to coronary artery disease, which can be diagnosed in early period by ultrasonography.
