| 摘 要： | 目的: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.方法:50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.结果:G-MPI诊断的特异性和准确性方面要明显高于NG-MPI(P<0.05),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<0.05).G-MPI诊断的敏感性要高于ETT,P<0.05.在诊断的准确性方面G-MPI与ETT相比有极显著性差异(P<0.01).结论: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: | Objective: To investigate the diagnostic value of 99 Tc m-MIBI ECG-gated myocardial perfusion imaging (G-MPI) in left bundle branch block (LBBB) combined coronary artery disease. Methods: Fifty patients with LBBB were chosen in this study and all underwent loading/resting G-MPI, exercise treadmill test (ETT) and echocardiography. The diagnostic accuracy of each non-invasive method were compared. Results: The specificity and accuracy of G-MPI were significantly higher than NG-MPI (P<0.05). The sensitivity and accuracy of G-MPI were significantly higher than ETT (P<0.05, P<0.01). Conclusion: G-MPI had higher accuracy in diagnosing coronary artery disease in patients with LBBB. |
