冠状动脉CT血管成像对急性冠脉综合征患者斑块性质的诊断价值

Value of coronary CT angiography in the diagnosisof plaque characteristics in patients with acute coronary syndrome

    摘要
  • 摘要:
      目的  探讨冠状动脉CT血管成像(CTA)对急性冠脉综合征(ACS)患者斑块性质的诊断价值。
      方法  选取本院100例ACS患者为研究组，同期选取50例稳定型心绞痛患者为对照组，均实行CTA诊断。以冠状动脉血管造影检查结果作为金标准，评估CTA对本组ACS患者斑块性质的诊断准确度、特异度、敏感度。
      结果  CTA对本组ACS患者斑块性质的诊断准确度是96.00%(96/100)、特异度是90.00%(27/30)、敏感度是98.57%(69/70); 研究组非钙化斑块负荷、阻力指数(RI)均显著高于对照组，而斑块最小密度值显著低于对照组(P < 0.05)。
      结论  CTA对ACS患者斑块性质的诊断准确度、特异度、敏感度均较高，可准确鉴别ACS患者和稳定型心绞痛患者斑块负荷。

     

    Abstract:
      Objective  To investigate the diagnostic value of coronary CT angiography (CTA) in plaque characteristics of patients with acute coronary syndrome (ACS).
      Methods  A total of 100 patients with ACS were selected as study group, and 50 patients with stable angina pectoris during the same period were selected as control group. All patients were diagnosed by CTA. Taking coronary angiography as the gold standard, the diagnostic accuracy, specificity and sensitivity of CTA for plaque characteristics of ACS patients were evaluated.
      Results  The diagnostic accuracy, specificity and sensitivity of CTA were 96.00% (96/100), 90.00% (27/30) and 98.57% (69/70), respectively. The load and resistance index(RI) of non-calcified plaques in the study group were higher than those in the control group, while the minimum density of plaques was lower than those in the control group(P < 0.05).
      Conclusion  CTA has high accuracy, specificity and sensitivity in the diagnosis of plaque characteristics in ACS patients, and can accurately differentiate plaque load between ACS patients and stable angina patients.
