经胸冠状动脉超声与动态心电图对冠心病的诊断研究

Study on transthoracic coronary ultrasound and dynamic electrocardiogram in the diagnosis of coronary heart disease

目的:研究经胸冠状动脉超声与动态心电图诊断冠心病的临床效果。方法:收治疑似冠心病患者94例,回顾性分析患者的临床资料,所有患者均实施经胸冠状动脉超声与动态心电图诊断,比较两种方法的检出阳性率,计算其诊断的灵敏度、特异性、准确度。结果:经胸冠状动脉超声的灵敏度、特异性、准确度均显著优于动态心电图(P<0.05)。结论:采用经胸冠状动脉超声检查冠心病具有良好的灵敏度、特异性,可以为冠心病患者的术前诊断及介入手术术后支架处血管的通畅程度判断、预后分析等提供可靠依据。

Objective:To study the clinical effect of transthoracic coronary ultrasound and dynamic electrocardiogram in thediagnosis of coronary heart disease.Methods:94 patients with suspected coronary artery disease were selected.The clinical data ofpatients were retrospectively analyzed.All patients were diagnosed by transthoracic coronary ultrasound and dynamicelectrocardiogram.The detection positive rate of two methods were compared.The sensitivity,specificity and accuracy of thediagnosis were calculated.Results:The sensitivity,specificity and accuracy of transthoracic coronary ultrasound were significantlybetter than those of dynamic electrocardiogram(P<0.05).Conclusion:Using transthoracic coronary ultrasound in the examinationof coronary heart disease has good sensitivity and specificity.It can provide a reliable basis for the preoperative diagnosis ofcoronary artery disease,stents blood vessels unobstructed degree judgment after interventional operation and prognosis analysis.
