Abstract

Catheter-Based Coronary Angiography (CCA) and computed tomography coronary angiography (CTCA) are both used in the diagnosis of coronary artery disease (CAD). The current study aims to evaluate the accuracy of CTCA compared to CCA as a gold standard to find an alternative method to CCA in diagnosing CAD. 65 patients with suspected coronary heart disease underwent CCA and CTCA procedures using 128-section computed tomography (MDCT). The CT images were analyzed by three consultant radiologists with more than 10 years of experience. CCA and CTCA reports were compared, and sensitivity, specificity, positive expected value (PPV) and negative expected value (NPV) were analyzed. These values were found for the 'per artery' and 'per patient' criteria. The results showed that the sensitivity, specificity of PPV, and NPV for accuracy measures of 'per patient' analyzes were 96.8%, 97%, 96.8%, and 97%, respectively. For left main coronary artery (LM), left anterior Descending (LAD), Circumflex artery (CX), and Right Coronary Artery (RCA), the results were 100%, 98.40%, 75%, 100%, 90.6%, 97%, 96.6 %, 91.4% and 61.1%, 100%, 100%, 87% and 73.70%, 97.8%, 93.3%, 90%, respectively with p<.001. The study concluded that it is possible to use MDCT as an alternative part of CCA, which can be used to reduce CCA pain, procedure time, and at a lower cost.

评价128段多层计算机断层扫描(MDCT)检测冠状动脉狭窄的准确性

基于导管的冠状动脉造影(CCA)和计算机断层冠状动脉造影(CTCA)都被用于冠状动脉疾病(CAD)的诊断。本研究旨在评估CTCA与CCA作为金标准的准确性，以寻找CCA诊断CAD的替代方法。65例疑似冠心病患者采用128段计算机断层扫描(MDCT)行CCA和CTCA手术。CT图像由三名具有10年以上经验的放射科顾问医师进行分析。比较CCA和CTCA报告，分析敏感性、特异性、阳性期望值(PPV)和阴性期望值(NPV)。这些值适用于“每条动脉”和“每个病人”标准。结果显示，PPV和NPV对“每位患者”分析准确性测量的敏感性、特异性分别为96.8%、97%、96.8%和97%。左冠状动脉主干(LM)、左前降支(LAD)、旋支(CX)、右冠状动脉主干(RCA)分别为100%、98.40%、75%、100%、90.6%、97%、96.6%、91.4%、61.1%、100%、100%、87%、73.70%、97.8%、93.3%、90%，p< 0.001。该研究得出结论，MDCT可以作为CCA的替代部分，可以减少CCA的疼痛、手术时间和较低的成本。
