  •   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.
