摘要

为探讨99Tcm-MIBI门控心肌灌注显像（G-MPI）在左束支传导阻滞（LBBB）病人中诊断冠心病的价值。21例LBBB患者均完成二日法门控负荷/静息MPI、心电图平板运动试验（ETT）、超声心动图检查。比较非门控心肌灌注显像（NG-MPI）和G-MPI在LBBB病人中诊断冠心病的准确性

并对各种无创性诊断技术的诊断价值进行比较。G-MPI诊断的特异性（P=0.041）和准确性（χ2=4.725

P=0.030）方面要明显高于NG-MPI

G-MPI与NG-MPI相比能明显提高对LAD病变诊断的特异性和准确性（P均=0.020）。G-MPI诊断的敏感性要高于ETT

P=0.030。在诊断的准确性方面

G-MPI与ETT相比有极显著性差异（χ2=7.467

P=0.006）。门控心肌灌注显像在LBBB病人中诊断冠心病具有较高的准确性

与非门控心肌显像和其它无创性诊断技术相比具有一定的优势。

Abstract

To investigate the diagnostic value of 99Tcm-MIBI ECG-gated myocardial perfusion imaging (G-MPI) in left bundle branch block (LBBB)

twenty-one patients with LBBB underwent stress/rest G-MPI

ETT and echocardiography. Accuracy of all non-invasive methods was assessed. The specificity and accuracy of G-MPI were significantly higher than NG-MPI (P=0.020). The sensitivity and accuracy of G-MPI were significantly higher than ETT (P=0.030 and P=0.006

respectively). G-MPI had high accuracy in diagnosing CAD in patients with LBBB.
