Methods For coronary angiography Judkin' s method was used; IAMI was diagnosed by the 1979 WHO's standard of ISHD and ECG was separately measured by two doctors. Results Most of IAMI with polybranch coronary or its collateral disease (32. 5% and 42. 5% ) and only 10 cases (25% ) with single branch coronary disease, whose ECGs were untypical. Conclusion IAMI with single-branch coronary disease might express as mild symptoms and have no typical ECG change. While typical ECG change emerges, the coronary artery always showed poly-branch disease or collateral branch obstruction and the disease would be advanced. It is important to pay more attention to the cases of IAMI without classic ECG change so as to give diagnosis and treatment them in time.展开更多
