Background: The objectives of this study were to assess the relation of blood groups and the rate of successful angioplasty in patients with ST-elevated myocardial infarction (STEMI) and also to investigate long-term adverse outcomes follow-up. Materials and Methods: In this study, 500 eligible patients with definitive diagnosis of STEMI who underwent primary percutaneous coronary intervention (PCI) were followed up for 3 years. The patient's angiography images were examined and thrombolysis in myocardial infarction (TIMI) flow rate and coronary artery patency rate were evaluated in different ABO blood groups. All patients were followed up after 3 years based on major adverse cardiovascular events. Results: There was no significant difference in coronary artery patency rate between the patients of the different blood types with respect to TIMI flow before (P = 0.19) and after revascularization (P = 0.69). The incidence of atrial fibrillation (AF) in blood Group A was the highest. Death in the blood Groups AB and O was significantly higher than the other groups. No significant differences were seen in different blood groups in the frequency of mortality (P = 0.13), myocardial infarction (P = 0.46), heart failure (P = 0.83), re-hospitalization, angiography (P = 0.90), PCI (P = 0.94), coronary artery bypass graft (P = 0.26), implantable cardioverter defibrillator (ICD) implantation (P = 0.26), and mitral regurgitation (P = 0.88). Conclusion: The incidence of AF in blood Group A and inhospital mortality in blood Groups AB and O were the highest. The blood group may be considered in assessment of clinical risk in STEMI patients.
