摘　　要：目的探究二维超声诊断老年冠心病颈动脉硬化的特征及血流动力学变化。方法选择焦作市第二人民医院2022年3月—2023年3月疑似冠心病患者234例作为研究对象,均行颈动脉超声诊断、冠脉CTA诊断。以冠脉CTA诊断结果为标准,将患者分为冠心病组、非冠心病组,对比两组患者的一般资料、颈动脉超声参数、血流动力学变化。结果CTA诊断结果可见,0类共56例(23.93%),1类共94例(40.17%),2类共33例(14.10%),3类共29例(12.39%),4类共22例(9.40%)。冠心病患者共84例,非冠心病患者150例。冠心病组患者男性发生率、年龄均高于非冠心病组,差异有统计学意义(P<0.05)。冠心病组患者的斑块检出率、平均IMT、斑块评分、半定量积分、等级积分、最大斑块厚度、最大斑块长度均高于非冠心病组,差异有统计学意义(P<0.05)。冠心病组患者的PSV、RI均高于非冠心病组,差异有统计学意义(P<0.05)。结论冠心病患者可采用二维超声诊断,通过观察斑块评分、等级积分、最大斑块长度、最大斑块厚度等评估疾病。同时,冠心病患者的PSV、RI升高,为疾病的诊断提供一定参考价值。Objective To explore the characteristics and hemodynamic changes of carotid artery sclerosis in elderly patients with coronary heart disease diagnosed by two-dimensional ultrasound.Methods From March 2022 to March 2023 in Jiaozuo Second People's Hospital,234 patients with suspected coronary heart disease were selected as the research subjects,and all the carotid artery ultrasound diagnosis and CTA diagnosis were performed.Using CTA diagnostic results as the standard,patients were divided into CHD and non-CHD groups,and the general data,carotid ultrasound parameters and hemodynamic changes of the two groups were compared.Results According to CTA diagnosis,56(23.93%)in category 0,94(40.17%)in category 1,33(14.10%)in category 2,29(12.39%)in category 3,and 22(9.40%)in category 4.There were 84 patients with CHD and 150 patients without CHD.The male incidence and age of CHD guoup were higher than those of non-CHD group,and the difference was statistically significant(P<0.05).The plaque detection rate,mean IMT,plaque score,semi-quantitative score,grade integral,maximum plaque thickness and maximum plaque length of CHD group were all higher than those of non-CHD group,with a statistically significant difference(P<0.05).PSV and RI of CHD group were higher than those of non-CHD group,and the difference was statistically significant(P<0.05).Conclusion Patients with coronary heart disease can be diagnosed by two-dimensional ultrasound,and the disease is assessed by observing the plaque score,grade score,maximum plaque length,and maximum plaque thickness.At the same time,PSV and RI increased in patients with coronary heart disease,providing certain reference value for the diagnosis of diseases.
