Key result
Bare metal stents linked to ~7.5-fold higher stent thrombosis risk versus DES, alongside dyslipidemia and lower LVEF.
Why the study?
Despite improvements in the quality of PCI over recent decades, patient-related risk factors for the development of stent thrombosis required assessment.

Reduced left ventricular ejection fraction, dyslipidemia, and the use of bare metal stents are independent predictors of stent thrombosis following percutaneous coronary intervention.
May inform stent selection in high-risk PCI; supports consensus yet leaves open prospective validation.
Introduction. Over the past decades, there has been a significant improvement in the quality of percutaneous coronary interventions (PCI). The goal of this study is to assess patient related risk factors for the development of ST in patients treated with PCI. Results. According to the study, the percentage of patients with ST who had bare metal stents (BMS) was significantly higher (72.41%) than that of patients without ST (27.59%). Conclusion. Lower ejection fraction, presence of dyslipidemia and usage of BMS were identified as independent predictors of ST.

Horozic et al. (2025) conducted a cross-sectional in Coronary Stent Thrombosis (n=231). Bare metal stent (BMS) vs. Drug-eluting stent (DES) was evaluated on Development of stent thrombosis (OR 7.474, 95% CI 2.605-21.447, p=<0.001). The use of bare metal stents, presence of dyslipidemia, and lower ejection fraction were identified as independent predictors of coronary stent thrombosis, with bare metal stents associated with a 7.5-fold increased risk (OR 7.474) compared to drug-eluting stents.
