冠状动脉CT造影对冠心病的临床诊断价值研究

目的:探讨研究冠状动脉CT造影检查对冠心病的临床诊断价值。方法:收集我院2012年1月至2013年10月共计70例临床怀疑为冠心病的患者,对这些患者分别进行冠状动脉CT造影检查和数字减影冠状动脉造影(DSA)检查,记录这两项检查所得结果及数据,以检查数据为基础对冠状动脉CT造影和数字减影冠状动脉造影检查的临床实验效果进行对比研究。结果:70例病人均可顺利完成以上两种检查,按照数字减影冠状动脉造影检查的标准,冠状动脉CT造影的敏感度为92.2%,特异度为97.4%、阳性预测率为90.5%、阴性预测率98%。结论:相对于数字减影冠状动脉造影检查,冠状动脉CT造影检查是一种更加安全、可靠、无创且更具临床指导意义的检测技术,因此可以推荐作为冠心病诊断的首选方法。

Evaluation of Coronary CT Angiography for Diagnosis of Coronary Heart Disease

Objective:To study the value of coronary CT angiography for coronary heart disease.Methods:70 patients with suspected coronary heart disease had been collected from January 2012 to October 2013, the coronary CT angiography and digital subtraction angiography (DSA) inspections have been finished in groups for these patients to comparative study the clinical application effectiveness of these two inspection methods based on the inspection results and data.Results:All 70 patients can complete these two inspections successfully. According to the principles of digital subtraction angiography coronary angiography inspection, the sensitivity of coronary CT angiography is 92.2 %, specificity is 97.4 %, positive predictive value is 90.5 %, negative predictive value is 98 %.Conclusion:Compared with the DSA, the coronary CT angiography inspection is a safer, more reliable, non-invasive and with better clinical significance inspection technique. Therefore, the coronary CT angiography inspection can be recommended as the first choose diagnostic approach for coronary heart disease.
