Abstract Introduction: This study investigated how non-O blood groups relate to thrombus burden (TB) and prognosis in ST-segment elevation myocardial infarction (STEMI) patients, aiming to shed light on their association with thrombotic complications in cardiovascular diseases. Methods: Retrospectively, 1,180 STEMI patients undergoing primary percutaneous coronary intervention were included. The study population was divided into groups according to TB status and the groups were compared in terms of basic clinical characteristics, laboratory parameters and ABO blood group types. In addition, short-term (30 days) and long-term (12 months) clinical outcomes were assessed to evaluate the prognostic implications. Results: The analysis revealed a significant association between non-O blood groups and increased TB in STEMI patients (p = 0.001). Non-O blood group was independently associated with high TB (OR: 1.726, 95% confidence interval [CI]: 1.279–2.330, p < 0.001). Additionally, patients with non-O blood groups had higher short and long-term mortality rates (hazard ratio [HR]: 2.480, 95% CI: 1.361–4.520, p = 0.003; HR: 2.347, 95% CI: 1.433–3.844, p = 0.001; respectively). Conclusions: This study emphasizes the significance of the ABO blood group system in STEMI outcomes, associating non-O blood groups with higher TB and poorer clinical outcomes. While proposing personalized treatment strategies based on blood group status to improve reperfusion interventions and outcomes, additional trials are needed to comprehensively evaluate their impact. HighlightsNon-O blood groups in ST-segment elevation myocardial infarction (STEMI) patients are linked to higher thrombus burden, suggesting implications for reperfusion interventions.Non-O blood group patients have higher mortality rates, stressing blood group’s importance in STEMI care.Non-O blood group independently predicts high thrombus burden, highlighting its role in STEMI outcomes.This study underscores customizing treatment based on blood group for better outcomes in reperfusion interventions.
