目的探析老年冠心病患者应用颈动脉超声的诊断价值。方法将本院2015年2月~2017年3月1500例冠心病筛查中120例经冠状动脉造影确诊的老年冠心病患者按检查方式分组,实验组采用颈动脉超声检查,对照组采用心脏彩超和心电图检查,分析两组诊断性能指标,同时探讨颈动脉超声中冠心病与非冠心病老年患者的血流动力学指标。结果实验组诊断性能指标均优于对照组(P<0.05);冠心病患者与非冠心病患者EDV差异不显著(P>0.0 5),而冠心病患者PSV与RI分别为(77.15±11.94)cm/s、(0.76±0.08),与非冠心病患者差异显著(P<0.05)。结论颈动脉超声可准确反映老年冠心病患者的血流动力学指标,同时提高其确诊率,建议在临床上广泛应用。
Objective To investigate the diagnostic value of carotid artery ultrasound in elderly patients with coronary heart disease. Methods From February 2015 to March 2017, 120 cases of coronary heart disease diagnosed by coronary angiography in 1500 cases of coronary heart disease screening were divided into groups according to the examination method. The experimental group was given carotid ultrasonography and the control group was treated with echocardiography And electrocardiogram (ECG). The diagnostic performance of the two groups were analyzed. The hemodynamic indexes of elderly patients with coronary heart disease and non-coronary heart disease were also studied. Results The diagnostic performance of experimental group was better than that of control group (P <0.05). There was no significant difference in EDV between CHD patients and non-CHD patients (P> 0.05), while the PSV and RI of CHD patients were (77.15 ± 11.94) cm / s and (0.76 ± 0.08) respectively, which were significantly different from those of non-CHD patients (P <0.05). Conclusion Carotid artery ultrasound can accurately reflect the hemodynamic parameters of elderly patients with coronary heart disease, while improving the diagnosis rate, it is recommended in the clinical widely used.
