320螺旋CT与冠状动脉造影在冠心病诊断方面的对比分析

320 spiral CT and coronary angiography in the diagnosis of coronary heart disease compared

目的探讨螺旋CT冠脉成像(CTA)与冠脉造影(CAG)对冠心病诊断的价值。方法选取本院2005年2月到2010年1月中住院或已确诊冠心病患者280例,同时做了螺旋CT冠状动脉成像检查和冠状动脉造影检查的患者。结论 280例患者均获得良好的三维重建,CTA诊断冠心病灵敏度为64.3%,特异度为92.1%,阳性预测值为89.77%,阴性预测值为97.90%。在显示冠状动脉狭窄分级方面具有良好的一致性。结论螺旋CT冠脉成像是一种安全、简便、无创、经济较为可靠的冠脉病变无创检查方法,在冠状动脉造影中具有良好的发展前景,对冠脉主要血管的中、重度狭窄病变冠状动脉疾患的筛选,开口变异,对钙化病变诊断率优于冠脉造影,为临床治疗及无创筛选提供可靠的诊断依据。

Objective To evaluate spiral CT coronary angiography（CTA）and coronary angiography（CAG）for the diagnosis of coronary heart disease.Methods Hospital in February 2005 to Mid 2010,had been diagnosed 280 cases of coronary heart disease,while spiral CT coronary angiography did check.Results Ocoronary angiography in patients with 280 patients have received a good three-dimensional reconstruction,CTA diagnosis of coronary heart disease was 64.3% sensitivity and specificity of 92.1%,positive predictive value was 89.77%,97.90% negative predictive value.Coronary artery stenosis grading in the display had a good consistency.Conclusion The spiral CT coronary angiography is a safe,simple,noninvasive,economic and more reliable noninvasive method for coronary artery disease in coronary angiography has good development prospects in the major blood vessels of the coronary artery,severe coronary artery stenosis disease screening,open variation,on the calcification rate of better diagnostic coronary angiography for clinical treatment and provide a reliable non-invasive screening diagnosis.
