多层螺旋CT诊断急性冠脉综合征的临床价值

Clinical research of diagnosing acute coronary syndrome with multi-spiral computed tomography

目的探讨多层螺旋CT在诊断各类冠心病,特别是对于诊断急性冠脉综合征(ACS)的价值。方法对我院2006年1～6月期间63例胸痛患者的多层螺旋CT冠脉成像诊断和临床相关指标进行回顾性分析。结果33例被确诊为冠心病。急性冠脉综合征(ACS)组(19例)的中、重度狭窄中软斑块检出与稳定型心绞痛(SA)组(14例)差异有统计学意义(P<0.05)。超敏C反应蛋白(Hs-CRP)和肌钙蛋白(ICTnI)的升高与斑块不稳定有关(P<0.01),与多层螺旋CT成像共同组合诊断提示斑块破裂。结论多层螺旋CT、超敏C反应蛋白(Hs-CRP)和肌钙蛋白(ICTnI)联合应用是无创诊断冠心病,检出易损斑块的重要手段。

Objective To investigate multi-spiral computed tomograph＇s value of diagnosing different types of coronary heart disease （CHD）, especially the acute coronary syndrome （ACS）. Methods The MSCT results and clinical data of 63 patients of pain chest in our hospital were analyzed retrospectivly during Janury to June 2006. Results 33 cases were diagnosed CHD. There was obvious difference between ACS （19 cases ） and SA （14 cases） in checking soft plaques from moderate and serious stenosis （P〈0.05）. The relationship was examined between the increase of Hs-CRP and troponin I and the unstabiliry of plaque（P〈0.01 ）. Hs-CRP,troponin I and MSCT imagement showed that the plaque had been broken. Conclusion The united application of MSCT,Hs-CRP and troponin I was important method in diagonosing CHD and checking ruptured plaque for non-invading method.
