简介：　　【摘 要】目的 探究冠心病并發心绞痛患者冠脉 CT血管造影与颈动脉粥样硬化的关联性。方法 选择 2018年 2月 -2019年 5月来我院就诊的 160例冠心病并发心绞痛患者，通过随机数表法均分为对照组和观察组，每组 80例，对照组采用颈动脉 B超检查，观察组采用冠脉 CT血管造影进行检查。记录患者颈动脉内中膜厚度、颈动脉斑块积分、斑块类别及个数、颈总动脉内径。结果 观察组患者冠脉斑块的数目显著大于对照组患者颈动脉斑块的数目（ P<0.05） ;观察组患者总斑块、混合斑、非钙化斑数目均与对照组具有相关性（ P<0.05） ;观察组患者的总斑块、混合斑、钙化斑、非钙化斑数目与对照组患者混合斑、硬斑数目具有显著相关性（ P<0.05）。结论 冠心病并发心绞痛患者冠脉 CT血管造影与颈动脉粥样硬化具有显著关联性，在临床上根据患者颈动脉 B超的结果来判断是否需要进行冠脉 CT血管造影。  　　【关键词】冠心病 ;心绞痛 ;冠脉 CT血管造影 ;颈动脉粥样硬化  [Abstract] Objective To explore the correlation between coronary CT angiography and carotid atherosclerosis in patients with coronary heart disease complicated with angina pectoris. Methods 160 patients with coronary heart disease complicated with angina pectoris in our hospital from February 2018 to may 2019 were randomly divided into control group and observation group, with 80 cases in each group. The control group was examined by carotid ultrasound, and the observation group was examined by coronary CT angiography. The intima-media thickness of carotid artery, plaque score, type and number of plaque, and diameter of common carotid artery were recorded. Results the number of coronary plaque in the observation group was significantly higher than that in the control group (P < 0.05); the number of total plaque, mixed plaque and non calcified plaque in the observation group was correlated with that in the control group (P < 0.05); The number of total plaque, mixed plaque, calcified plaque and non calcified plaque in the observation group was significantly correlated with the number of mixed plaque and hard plaque in the control group (P < 0.05). Conclusion there is a significant correlation between coronary artery CT angiography and carotid atherosclerosis in patients with coronary heart disease complicated with angina pectoris.
