超声对冠状动脉粥样硬化与颈动脉粥样硬化的相关性研究

目的 探讨冠心病患者颈动脉粥样硬化与冠状动脉粥样硬化的相关性。方法 对冠状动脉造影确诊为冠心病的89例患者和正常对照组的80例患者行颈动脉超声检查，对比观察颈动脉内-中膜厚度（IMT）、颈动脉有无斑块及斑块类型；对冠心病组不同支病变间IMT、颈动脉斑块积分及斑块发生率进行比较分析。结果 ①冠心病组患者的颈动脉粥样硬化斑块发生率为87．64％，显著高于对照组（33．75％，P〈0．01）。②两组颈动脉斑块以软斑最多见，冠心病组软斑占37．12％，扁平斑占16．59％，混合斑占25．76％，硬斑块占20．53％；对照组软斑占34．09％，扁平斑占22．73％，混合斑占25．00％，硬斑占18．18％。③不同支数冠状动脉病变者之间IMT、颈动脉斑块积分和斑块发生率比较，差异有统计学意义。结论 通过超声了解颈动脉病变可间接反映冠状动脉粥样硬化病变的程度。

Study on relationship between carotid atherosclerosis and coronary atherosclerosis by ultrasound

Objective To explore the relationship between carotid atherosclerosis and coronary atherosclersis in patients with cornary heart disease（CHD）. Methods Eighty - nine patients with CHD confirmed by coronary angiography and 80 eases in normal control group were examined by carotid ultrasound. The carotid intima - media thickness （ IMT）, carotid plaques and plaques types were observed, the IMT, carotid plaque score and plaque incidence in CHD group were analyzed. Results ①The incidence of carotid arteriosclerosis plaques in CHD group was 87.64% , which was higher than that in control group（33.75% ,P 〈0.01 ）. ②The soft plaques were the most common in the two groups. In CHD group, soft plaques occupied 37.12%, flat plaques occupied 16.59%, mixed plaques occupied 25.76% and hard plaques occupied 20.53%, while in control group, soft plaques occupied 34.09% , fiat plaques occuied 22.73% , mixed plaques occupied 25. 00% and hard plaques occupied 18. 18%. ③ There was significant difference of IMT, carotid plaques score and incidence of carotid atherosclerosis plaques in CHD group. Conclusion Ultrasound can indirectly reflect the degree of coronary atherosclersis.
