Delay angiographic findings of infarction related artery lesion after acute myocardial infarction

Objective:To observe infarction related artery(IRA)lesion of patients with acute myocardial infarction in delay coronary angiography.Methods:A total of 562 patients with acute myocardial infarction underwent coronary angiography 24 h to 3 months after onset.Results:In all patients,IRA were ascerntained in 559 cases,but,IRA of 4 patients with inferior myocardial infarction couldn't be ascerntained.In All of IRA,total occlusion were seen in 198 cases,Sub-total occlusion and severe stenosis in 244 cases,light stenosis in 83 cases,no stenosis in 38 cases.Conclusion:Regardless of thrombolysis or not,most of IRA are occlusion,sub-total occlusion and severe stenosis.For making clear coronary artery lesion,and recanalization in time,it is important that coronary angiography should be undertaken as early as possible.
