摘要
目的探讨颈动脉粥样硬化病变的性质、程度与冠状动脉狭窄程度之间的关系。方法选择265例经过冠状动脉造影的冠心病患者,常规做颈动脉超声检查。依据冠状动脉造影结果分为冠脉狭窄组和未狭窄组。按冠状动脉狭窄程度分为3个亚组,即轻度、中度、重度狭窄组。结果冠脉狭窄组颈动脉粥样硬化斑块检出率、内膜病变率和粥样斑块性质与未狭窄组比较,差异有统计学意义(P<0.01),且随着冠状动脉狭窄程度加重,颈动脉粥样斑块检出率明显增加(P<0.01)。经相关性分析,冠状动脉狭窄程度与颈动脉内膜增厚、斑块检出率和病变性质均呈正相关。结论颈动脉粥样硬化病变与冠状动脉狭窄病变有显著的相关性;对于冠心病高危人群常规颈动脉超声检查可用于估计冠状动脉粥样硬化病变的状况。
Objective To discuss the relationship between the character and degree of carotid artery atherosclerosis pathological change and the extent of coronary artery.Methods Consecutive 265 patients who underwent coronary angiography were enrolled, and were given routinely carotid artery B mode ultrasound. The patients were divided into coronary heart disease group and control group according to coronary angiography results. And the coronary heart disease group was divided into 3 subsets according to the degree of coronary artery stencsis, including mild stenesis, moderate stenosis, and severe stenosis. Results In coronary artery stenosis group, the incidence of carotid artery atheresclerosis and intima lesion, the characteristic of plaque had statistical difference compared with control group （ P 〈 0.01）. Followed the aggravation of the degree of coronary artery stenesis, the carotid artery atheroscleresis plaque incidence was obviously increased （ P 〈 0. 01）.. Otherwise,the degree of coronary stenesis had positive correlation with the numbers, characters and intima thickness of carotid artery. Conclusion There was significant correlation between carotid atheroscleresis pathological change and coronary artery atheroscleresis. The carotid ultrasound examination could help to predict the stenosis of coronary artery.
