摘　　要：目的探讨低剂量计算机断层摄影血管造影术与数字减影血管造影在冠状动脉中重度狭窄的诊断价值比较。方法选取88例确诊冠状动脉粥样硬化性心脏病(冠心病)的患者作为研究对象,应用血管分析软件进行图像重组,分析计算机断层摄影血管造影术检出冠状动脉斑块的性质,评估其狭窄情况,将其结果与对应节段数字减影血管造影检出的病变狭窄度进行对比。结果以数字减影血管造影作为金标准,计算机断层摄影血管造影术检出冠状动脉病变斑块所致中重度狭窄855节段,其中软斑块396节段、硬斑块459节段。通过两种检验方法对硬斑块导致中度狭窄、硬斑块导致重度狭窄、软斑块导致中度狭窄和软斑块导致重度狭窄进行检验,差异均无统计学意义(P>0.05)。结论低剂量计算机断层摄影血管造影术与数字减影血管造影检查对冠心病诊断都具有较高准确率,而低剂量计算机断层摄影血管造影术检查经济、方便、实用,可作为临床筛查冠心病的首选方法。Objective To compare the diagnostic value of low-dose computeirzed tomography angiography and digital subtraction angiography in severe coronary artery stenosis.Methods Eighty-eight patients with clinically suspected or confirmed coronary atherosclerotic heart disease were selected as the research objects.Vascular analysis software was applied to reconstruct images to analyze the nature of coronary plaques detected by computed tomography angiography and evaluate them for stenosis.The result were compared with the stenosis of the lesion detected by digital subtraction angiography of the corresponding segment.Results Digital subtraction angiography was taken as the gold standard,computed tomography angiography detected moderate to severe stenosis at 855 segments caused by coronary artery diseased plaques,there were 396 segments of soft plaques and 459 segments of hard plaques among them.The test results of hard plaques leading to moderate stenosis,hard plaques leading to severe stenosis,moderate stenosis caused by soft plaque and severe stenosis caused by soft plaque had no significant difference(P>0.05).Conclusion Both low-dose computeirzed tomography angiography and digital subtraction angiography have high accuracy in the diagnosis of coronary heart disease.Low-dose computer tomography angiography is economical,convenient and practical to be used as the first choice for clinical screening of coronary heart disease.
