Abstract
目的探讨心脏320排CT血管造影(CTA)筛查老年消化道出血并冠心病(CHD)的临床价值。方法选择71例无CHD病史的老年消化道出血患者,入院后2周内依次行常规12导联心电图(ECG)、心脏320排CTA检查,其中26例入院6周内行冠脉造影(CAG)检查;比较各种方法筛查CHD的临床价值。结果 71例患者中,CTA检查示CHD阳性29例(40.84%),ECG检查示CHD阳性19例(26.76%),CTA检查诊断CHD的阳性率明显高于ECG(P<0.05)。行CAG检查的26例患者中,CAG检查示CHD阳性15例(57.69%),CTA检查示CHD阳性16例(61.53%),两种方法诊断CHD的阳性率无统计学差异(P>0.05);CTA检查诊断CHD的灵敏度为100%,特异度为90.91%,阳性预测值为93.75%,阴性预测值为100%。结论心脏320排CTA可作为无创筛查老年消化道出血患者是否合并CHD的首选方法之一。
