The overall poor prognosis of stent thrombosis makes this rare complication, a devastating and hence extremely inportant one. A sub-analysis of TRITON-TIMI 38 study showed that stent thrombosis was associated with death or myocardial infarction in 89% (186/210) of patients[1]. In follow up studies after stent thrombosis, recurrent stent thrombosis has also been noticed, especially during the following six months[2].
Van Werkum et al[3] studied the long term outcome after definite stent thrombosis. 431 patients with definite stent thrombosis were enrolled in this multicenter registry. The primary end point was the composite of cardiac death and definite recurrent ST. The primary end point occurred in 111 patients after a median follow-up of 27.1 months. Clinical outcome was not affected by the type of previously implanted stent (drug-eluting or bare-metal stent) or the category of ST (early versus late). Authors concluded that the long-term clinical outcome after a first definite ST is unfavorable, with a high mortality and recurrence rate. Diabetes mellitus, left ventricular ejection fraction <45%, long total stent length, complex coronary lesions, TIMI flow grade <3 after percutaneous coronary intervention, and implantation of an additional coronary stent during the emergent percutaneous coronary intervention for the ST were associated with this unfavorable outcome.
