目的:评价冠心病诊断中采用64层螺旋CT冠脉成像的临床价值,为临床诊断冠心病提供参考。方法:选择139例疑似冠状动脉粥样硬化性心脏病(CHD)患者,以CAG检查结果为金标准,评价64层螺旋CT冠状动脉造影检查的准确性,并对冠状动脉病变不同部位和狭窄程度进行分析。结果:64层螺旋CT冠状动脉成像检查准确性96.40%(134/139),敏感性97.39%(112/115),特异性91.67%(22/24),阳性预测值98.25%(112/114)和阴性预测值88.00%(22/25)。与CAG结果比较,两者在疑似患者诊断上差异不显著(P>0.05)。结论:64层螺旋CT冠脉成像灵敏度高、特异性好,安全、无创,可作为高原地区CHD高危人群普查检查方法。
Objective: To evaluate the clinical value of 64-slice spiral CT coronary angiography in the diagnosis of coronary heart disease and provide a reference for the clinical diagnosis of coronary heart disease. Methods: One hundred and ninety-three patients with suspected coronary atherosclerotic heart disease (CHD) were selected. The accuracy of 64-slice spiral CT coronary angiography was evaluated based on the CAG test result. The coronary angiography Analyze. Results The accuracy of 64-slice spiral CT coronary angiography was 96.40% (134/139), the sensitivity was 97.39% (112/115), the specificity was 91.67% (22/24), and the positive predictive value was 98.25% (112/114) And negative predictive value of 88.00% (22/25). Compared with CAG results, there was no significant difference in the diagnosis of suspected patients (P> 0.05). Conclusion: 64-slice spiral CT coronary angiography is highly sensitive, specific, safe and non-invasive and can be used as a census method for CHD at high altitude.
