Text: Undersizing of the coronary stent, Thrombolysis In Myocardial Infarction flow grade < 3, present malignancy, presence of intermediate coronary artery disease proximal and distal to the culprit lesion, dissection, lack of aspirin, bifurcation lesions, ejection fraction < 30 %, and younger age were associated with ST. The lack of clopidogrel therapy at the time of ST in the first 30 days after the index PCI (hazard ratio [HR] : 36. 5, 95 % confidence interval [CI] : 8. 0 to 167. 8), between 30 days and 6 months after the index PCI (HR : 4. 6, 95 % CI : 1. 4 to 15. 3), and beyond 6 months (HR : 5. 9, 95 % CI : 1. 7 to 19. 8) after the index PCI was strongly associated with ST.
