目的探讨64层螺旋CT冠状动脉血管成像(64-MSCTA)联合颈动脉超声造影诊断冠心病的效果。方法 49例临床上已确诊为冠心病或疑似冠心病患者的64-MSCTA、颈动脉超声检查联合诊断资料,与单独采用64-MSCTA、颈动脉超声造影进行对比,并参照冠状动脉造影的检查结果 ,对64-MSCTA及颈动脉超声联合诊断冠心病的准确度进行评价。结果 64-MSCTA联合颈动脉超声诊断冠心病的准确度为95.9%,高于CTA组83.7%、颈动脉超声组79.6%,差异有统计学意义(P<0.05)。结论 64-MSCTA是一种简单、无创、安全的冠心病检查手段,颈动脉超声可准确预测病变程度,二者联合可优势互补提高诊断效果。
Objective To explore the effect of 64-slice spiral CT coronary angiography (64-MSCTA) combined with carotid ultrasonography in the diagnosis of coronary heart disease. Methods 49 cases of clinically diagnosed patients with coronary heart disease or suspected coronary heart disease by 64-MSCTA, carotid ultrasonography combined diagnostic data, compared with 64-MSCTA, carotid ultrasound contrast alone, and with reference to coronary angiography findings , 64-MSCTA and carotid ultrasound in the diagnosis of coronary heart disease to evaluate the accuracy. Results The accuracy of 64-MSCTA combined with carotid artery ultrasound in diagnosis of coronary heart disease was 95.9%, higher than that of CTA group (83.7%) and carotid artery ultrasound group (79.6%) (P <0.05). Conclusion 64-MSCTA is a simple, noninvasive and safe method of coronary heart disease examination. Carotid artery ultrasound can accurately predict the degree of disease. The combination of the two can enhance the diagnosis with complementary advantages.
