多层螺旋CT血管成像对急性冠脉事件的预测价值研究

Research on predictive values of Philips 256-slice CT angiography in acute coronary events

目的:探讨飞利浦256层螺旋CT冠状动脉血管造影(256-SCTCA)图像上多种形态的冠状动脉钙化与冠状动脉管腔狭窄的关系,通过冠状动脉钙化积分和冠状动脉成像对急性冠脉事件进行预测价值研究。方法:选取400例疑诊冠心病患者,采用256-SCTCA进行冠状动脉增强扫描以及冠状动脉数字减影血管造影(DSA),并运用自动分析软件进行冠状动脉钙化积分分析,比较两种检查方法的准确性,结合患者的临床资料对急性冠脉事件进行科学预测。结果:形态不同的冠状动脉钙化斑块导致局部管腔狭窄的比例均具有差异。以钙化积分标准对冠心病患者进行分组,伴随钙化积分的增多,冠心病的患病概率也随之增加。结论:多层螺旋CT冠状动脉钙化积分对诊断冠心病有较高的价值,钙化积分对判断冠状动脉狭窄程度有很高的特异度,值得临床推广和应用。

Objective： To investigate the Philips 256-slice CT coronary angiography images on a variety of forms of coronary artery calcification and coronary stenosis in relation to predict the value of the study of acute coronary events by coronary angiography and coronary artery calcification score. Methods： From May 2014 to February 2015 in the Third Affiliated Hospital of Qiqihar in patients with suspected coronary artery disease, with256-slice spiral CT coronary artery enhancement scanning and DSA, and using software of automatic analysis for coronary artery calcium score analysis, and comparing the accuracy of the two methods of inspection, combined with the clinical data of patients with scientific prediction of acute coronary events. Results： Different forms of coronary artery calcified plaque resulting in local differences in the proportion of luminal stenosis were statistically significant. AS calcium score standard are in grouped in patients with coronary heart disease（CHD）,along with increasing calcium score,the risk of coronary heart disease also increase. Conclusion： The diagnosis of coronary artery calcification score of coronary heart disease have a higher value. Calcium score for judging coronary artery stenosis to have high specific degrees, worthy of clinical popularization and application.
