摘要
目的研究多排CT(MDCT)、冠状动脉造影(CAG)对不稳定型心绞痛(UAP)患者冠状病变诊断的价值。方法将我院2017年3月-2018年3月年间收治的31例UAP患者纳为研究对象,其均在CAG检查前一周内行MDCT检查,且具备完善影像学资料,通过分析UAP患者影像学资料,评估MDCT在诊断UAP冠状病变中的应用价值。结果以CAG检查结果为金标准,MDCT在诊断UAP患者冠状动脉病变节段中的灵敏度、特异度及准确度分别89.89%、97.89%、95.34%;两种检查方法在评估血管狭窄程度中无显著性差异(P>0.05);MDCT共检出25块斑块,其中软斑块3个(12.00%)、纤维斑块7个(28.00%)、硬斑块13个(52.00%)、混合斑块2个(8.00%);MDCT与CAG在判断斑块性质中无显著性差异(P>0.05)。结论 MDCT与CAG在诊断UAP患者冠状动脉病变中的效果相似,且MDCT检查具有无创性,其检查参数CT值在辨别斑块性质,筛查易损斑块中具有很好的参考性。
Objective To study the value of multi-slice CT(MDCT) and coronary arteriography(CAG) in the diagnosis of coronary artery lesions in patients with unstable angina pectoris(UAP). Methods 31 patients with UAP admitted to our hospital from March 2017 to March 2018 were enrolled in the study. All patients were given MDCT examination within 1 w before CAG examination, and they had complete imaging data. By analyzing the imaging data of UAP patients, the application value of MDCT in the diagnosis of coronary artery lesions of UAP was evaluated. Results The results of CAG examination were taken as gold standard, and the sensitivity, specificity and accuracy of MDCT in the diagnosis of coronary artery lesions in UAP patients were 88.99%, 97.89% and 95.34% respectively. There was no significant difference in the assessment of vascular stenosis degree by the two methods(P>0.05). 25 plaques were detected by MDCT, including 3 soft plaques(12.00%), 7 fibrous plaques(28.00%), 13 hard plaques(52.00%) and 2 mixed plaques(8.00%). There was no significant difference in the determination of plaque properties between MDCT and CAG(P>0.05). Conclusion MDCT and CAG have similar effects in the diagnosis of coronary artery lesions in UAP patients, and MDCT examination is non-invasive, and its examination parameter CT value has a good reference in discriminating plaque properties and screening vulnerable plaques.
