目的:探讨组织多普勒成像(TPI)技术在冠心病(CHD)诊断中的应用价值。方法:随机选取CHD患者45例和42例健康志愿者进行分析,将87例研究对象分为对照组和实验组,对照组行常规超声检查,实验组使用TPI检查;对两组研究对象检测的敏感性、特异性、准确性和患者满意度进行比较。结果:实验组诊断的准确率为97.4%,对照组为89.5%,在可用度、敏感性、检查满意度等方面比较差异有显著统计学意义(P<0.05)。结论:TPI操作方便,准确率高,适用于CHD的诊断。
Objective: To investigate the value of tissue Doppler imaging (TPI) in the diagnosis of coronary heart disease (CHD). Methods: Forty-five CHD patients and 42 healthy volunteers were randomly selected. Eighty-seven subjects were divided into control group and experimental group. The control group underwent routine ultrasonography and the TPI group was used in the experimental group. Sensitivity, specificity, accuracy and patient satisfaction were compared. Results: The diagnostic accuracy of the experimental group was 97.4% and that of the control group was 89.5%. There was significant difference in the availability, sensitivity and examination satisfaction (P <0.05). Conclusion: TPI is easy to operate and has high accuracy. It is suitable for the diagnosis of CHD.
