64层CT冠状动脉造影对冠心病患者血运重建前后的评估作用

64 CT Coronary Angiography in Patients with Coronary Heart Disease(CHD) Before and After Reascularization Evaluation Function

目的探讨64层CT冠状动脉造影对冠心病患者血运重建前后的评估作用。方法随机选取2012/01至2015/12来我院接受治疗的56例冠心病患者纳入本研究。随机选取来我院进行健康体检的56例志愿者为健康人群。观察冠状动脉CTA重建图像结果、冠状动脉造影结果、CTA和CAG对比、64层螺旋CTA对冠状动脉各主要分支病变显示结果、CTA对中、重度冠脉病变判断结果的准确度。结果 56例患者,有52例患者出现不同部位和不同程度的狭窄,共104支狭窄血管,22例为单支病变,30例未多支病变。钙化斑块所引起狭窄42支,混合斑块引起狭窄10支,未钙化斑块引起狭窄52支。64层螺旋CTA和CAG对冠状动脉狭窄程度有较好的一致性。CTA对中、重度冠脉病变判断结果准确度较高(95.54%)。结论 64层CT冠状动脉造影对冠心病患者血运重建的价值较高,临床需结合实际情况,提高患者的生活质量。

Objective To investigate the 64 CT coronary angiography in patients xx, ith coronary heart disease （CHD） before and after reascularization evaluation function. Methods 56 patients with coronaW heart disease （CHD） were randomly selected as the research objective. 56 cases of volunteers for healthy people were researched as the health person. To observe coronary CTA reconstruction image results , the result of coronary angiography, CTA and comparison of the （TAG, 64 layer spiral CTA lesions show the results of the major coronaW arteries branch, the degree of accuracy of CTA for mediunl and severe coronary lesions. Results 56 patients, 52 patients of different parts and different degree of stenosis, a total of 104 narrow blood vessels, 22 cases of single lesion, 30 patients with multivessel lesions. Caused by calcification plaques 42, narrow narrow 10 mixed plaque, not narrow 52 branch of calcified plaque.64 layers spiral CTA and the CAG of coronary artery stenosis degree have good consistency. The degree of accuracy of CTA for medium and severe coronary lesions was high（95.54%）. Conclusion 64 CT coronary angiography in patients with coronarT heart disease （CHI）） reascularization value higher, clinical should be combined with the actual situation, to improve the patient＇s quality of life.
