摘　　要：目的 分析颈动脉内膜中层厚度(cIMT)与严重冠心病患者心脏猝死的关系。方法 回顾性分析2019年1月至2020年12月我院收治的150例严重冠心病患者的临床资料,依据是否发生心脏猝死分为对照组(n=100)和心脏猝死组(n=50)。比较两组的c IMT、颈总动脉硬化度、颈总动脉弹性系数,采用Spearman相关性分析探讨以上指标与心脏猝死的相关性。结果 心脏猝死组的cIMT、颈总动脉硬化度、颈总动脉弹性系数均高于对照组(P<0.05)。Spearman相关性分析显示,cIMT与心脏猝死呈正相关(r=0.67, P=0.000),颈总动脉硬化度、颈总动脉弹性系数与心脏猝死无相关性(r=0.23、 0.25, P=0.564、0.559)。结论 cIMT与严重冠心病患者心脏猝死关系密切,可作为临床预测心脏猝死风险的重要标志物。Objective To analyze the relationship between carotid intima-media thickness(cIMT) and sudden cardiac death in patients with severe coronary heart disease. Methods The clinical data of 150 patients with severe coronary heart disease admitted to our hospital from January 2019 to December 2020 were retrospectively analyzed, and all cases were divided into the control group(n = 100) and the sudden cardiac death group(n = 50) according to whether sudden cardiac death occurred. The cIMT, common carotid artery stiffness,and common carotid artery elasticity coefficient were compared between the two groups. Spearman correlation analysis was used to explore the correlations between the above indicators and sudden cardiac death. Results The cIMT, common carotid artery stiffness and common carotid artery elasticity coefficient in the sudden cardiac death group were higher than those in the control group(P <0.05). Spearman correlation analysis showed that cIMT was positively correlated with sudden cardiac death(r = 0.67, P = 0.000), while common carotid artery stiffness and common carotid artery elasticity coefficient had no correlation with sudden cardiac death(r = 0.23, P = 0.564;r = 0.25, P= 0.559). Conclusions cIMT is closely related to sudden cardiac death in patients with severe coronary heart disease, and can be used as an important marker to predict the risk of sudden cardiac death in clinic.
