Coronary artery disease (CAD) is an important cause of mortality and morbidity, therefore, recognizing its severity and related factors is important. This study was performed to evaluate the association between ratio for diameters of pulmonary artery to ascending aorta bifurcation in chest CT scan and number of involved vessels in coronary angiography. In this observational cross-sectional comparative study, 110 patients who were under coronary angiography in Firoozgar Hospital in 2017 were enrolled, and the association between ratio for diameters of pulmonary artery to ascending aorta bifurcation in their chest CT scan and number of involved vessels in angiography were assessed.
In this study, number of involved vessels in angiography was related to PA/Ao ratio (P = 0.001) and further vessels were accompanied with higher ratio. It may be concluded that, a higher ratio for diameters of pulmonary artery to ascending aorta bifurcation in chest CT scan is related to higher number of involved vessels in coronary angiography, and it may have a predictive role.
冠心病（CAD）是导致死亡和发病的重要原因，因此，识别其严重程度及其相关因素非常重要。本研究旨在评估胸部 CT 扫描中肺动脉与升主动脉分叉处直径比与冠状动脉造影中受累血管数之间的关系。在这项观察性横断面对比研究中，共纳入了 2017 年在菲尔多兹加尔医院进行冠状动脉造影的 110 名患者，并评估了其胸部 CT 扫描中肺动脉与升主动脉分叉处直径比与血管造影中受累血管数之间的关系。
本研究中，血管造影中受累血管数与 PA/Ao 比值（P = 0.001）相关，并且更多的血管伴随着更高的比值。可以得出结论，胸部 CT 扫描中肺动脉与升主动脉分叉处直径比越高，冠状动脉造影中受累血管数越高，具有预测作用。
