Abstract:Objective To evaluate reliability of exercise -rest 99 Tcm -MIBI myocardial perfusion imaging(MPI)in assess-ing the myocardial ischemia in patients with myocardial bridging.Methods All selected patients underwent the coronary angiog-raphy,MPI and exercise electrocardiogram(ECG),the severity of myocardial bridging was evaluated by the Nobel Grading stand-ard,and the symptom of angina was evaluated by CCS grading standard.The positive rate of myocardial ischemia in patients with myocardial bridging was evaluated by the MPI and exercise ECG. Results The positive rate of myocardial ischemia diagnosed by MPI was much higher than exercise ECG(P <0.05),patients with Nobel Ⅲ level had a higher positive rate than patients with NobelⅠlevel(P <0.05),patients with CCS Ⅲ level had a higher positive rate of myocardial ischemia diagnosed by MPI than patients with CCSⅠlevel and CCS Ⅱ level(P <0.05).Conclusion MPI could evaluate the myocardial ischemia more sensi-tively than exercise ECG in patients with myocardial bridging.
