目的比较常规心电图ST-T改变与256螺旋CT冠状动脉造影在冠心病诊断中的应用。方法两组患者均进行心电图分析及256螺旋CT冠状动脉造影术(CTA)。结果 256螺旋CT冠状动脉造影冠心病诊断阳性率为76%,体表心电图冠心病诊断阳性率为68%,两组相比差异有统计学意义(P<0.05)。结论常规心电图对冠心病的诊断有一定价值,256螺旋CT冠状动脉造影可明显提高冠心病的诊断阳性率。
Objective To compare the clinical application of ST-T changes and 256-slice spiral CT coronary angiography in the diagnosis of coronary heart disease. Methods Two groups of patients underwent ECG analysis and 256 spiral CT coronary angiography (CTA). Results The positive rate of coronary heart disease diagnosed by 256 spiral CT coronary angiography was 76%, and the positive rate of coronary heart disease by surface electrocardiogram was 68%. There was significant difference between the two groups (P <0.05). Conclusion Conventional electrocardiogram has a certain value in the diagnosis of coronary heart disease. 256-slice spiral CT coronary angiography can significantly improve the diagnostic accuracy of coronary heart disease.
