AI Article Synopsis
- This study explores the link between ABO blood groups and the risk of early stent thrombosis in patients who underwent coronary interventions, focusing particularly on non-O blood groups and their association with cardiovascular issues.
- Among 10,714 patients, only 0.73% experienced early stent thrombosis, and while non-O blood groups weren't significantly linked, those with B-antigens (B and AB blood types) showed a higher risk for early thrombosis compared to O type.
- The findings suggest that B-antigen presence is a notable factor in early stent thrombosis risk, indicating a need for more research to understand the biological mechanisms behind this relationship.
Article Abstract
Background: ABO blood group's influence on cardiovascular risk, particularly in venous thromboembolism and coronary artery disease (CAD), is well-studied, with non-O blood groups associated with heightened CAD risk. However, its impact on stent thrombosis remains an unexplored area, prompting the question of whether ABO blood groups are also associated with risk of early stent thrombosis.
Objectives: The primary objective of this study was to analyze the impact of ABO blood groups on the occurrence of early (≤30 days) stent thrombosis.
Methods: The study included 10,714 consecutive patients who underwent percutaneous coronary intervention (PCI) with implantation of drug-eluting stents (DES) at a tertiary care hospital. Among these, 78 patients (0.73 %) experienced early stent thrombosis. Propensity score matching was conducted using cardiovascular risk factors and predictors of stent thrombosis, including age, sex, diabetes, hypertension, smoking, hypercholesterinemia, and clinical presentation.
Results: The presence of non-0 blood groups (blood groups A, B and AB; OR 1.48; 95 % CI 0.74-2.97; p = 0.27) and of A-antigen (blood groups A, AB; OR 0.93; 95 % CI 0.51-1.84; p = 0.89) was not associated early stent thrombosis, respectively. In contrast, patients with B-antigen (blood groups B, AB) were at higher risk of early stent thrombosis as compared to patients with blood group 0 (OR 2.48; 95 % CI 1.08-5.69; p = 0.019).
Conclusion: The presence of blood group antigen B (blood groups B and AB) emerged as a significant factor associated with early stent thrombosis. Further investigations are warranted to elucidate the specific biological mechanisms through which ABO blood group antigens could influence stent thrombosis.

Impact of Anemia and Acquired Anemia on in-Hospital Mortality of Acute Coronary Syndrome Patients.
Int J Gen Med
December 2024
Department of Cardiology, Medipol Istanbul University Faculty of Medicine, Istanbul, Turkey.
Objective: To investigate the associations of anemia-related parameters, with in-hospital mortality after acute coronary syndrome (ACS), as well as factors associated with prior anemia (PA) and hospital-acquired anemia (HAA) in patients with ACS.
Methods: This was a retrospective cohort study conducted between June 2021 and May 2023. The data of patients diagnosed with ACS who were hospitalized and treated in our hospital were recorded, including age and sex, smoking and comorbidity status, laboratory findings, CHA2DS2-VASc scores, prior medication use, left ventricular ejection fraction, ACS type, the synergy between percutaneous intervention with taxus drug-eluting stents and cardiac surgery (SYNTAX) scores, stent thrombosis status and mortality status.

Introduction: The optimal revascularization strategy for patients with myocardial infarction (MI) and multivessel coronary artery disease (CAD) remains an area of research and debate. Fractional flow reserve (FFR)-guided complete revascularization (CR) by percutaneous coronary intervention (PCI) has emerged as an alternative to traditional culprit-only PCI.
Objective: To investigate the outcomes of FFR-guided CR versus culprit-only PCI in patients with MI and multivessel CAD.

Objective: This study aimed to compare the efficacy and safety of intravascular ultrasound (IVUS)-guided coronary intravascular lithotripsy and rotational atherectomy in treating severe coronary artery calcification.
Methods: A retrospective analysis of 60 patients who underwent percutaneous coronary intervention at the General Hospital of Ningxia Medical University from October 2022 to August 2023 was conducted. The patients were divided into two groups: 30 received IVUS-guided coronary intravascular lithotripsy and 30 underwent IVUS-guided rotational atherectomy.
