Ohno Y, Yamaji K, Kohsaka S, et al. - Researchers used nationwide registration system for percutaneous coronary interventions (J-PCI) in order to evaluate the characteristics in patients with a clinical presentation of stent thrombosis (ST) as well as their in-hospital results. Participants were acute coronary syndrome (ACS) patients undergoing PCI with clinical findings of definite ST from January 2014 to December 2016. Younger age but a higher incidence of prior myocardial infarction was noted in patients with ST vs those without. Increased rate of crude in-hospital death was observed in ST patients. Following full match comparison, a significantly higher incidence of recurrent ST (post-PCI) was observed in ST patients vs ACS patients presenting without ST. Overall, findings revealed a significantly higher incidence of in-hospital mortality and cardiovascular complications, including recurrent ST, in patients with ST vs those without, despite the younger age of patients with ST.
