title: Characteristics and outcome of angiographically confirmed stent thrombosis.
abstract: Retrospective analysis of registry data on angiographically confirmed stent thromboses recorded between 1998 and 2007. In total, 58 cases of stent thrombosis occurred, of which 15 were in drug-eluting stents. Fourteen (24.1%) stent thromboses were acute, 27 (46.6%) were subacute, 9 (15.5%) were late, and 8 (13.8%) were very late. The most common clinical presentation was ST-elevation myocardial infarction (48-82.8%) and 3 (5.2%) patients died during admission. Balloon angioplasty was the most frequently used treatment (25-43.1%). During follow-up (median period, 1.7 years), 9 (16.4%) patients presented with recurrence of the stent thrombosis between 5 and 166 days after the first occurrence. One patient presented with two recurrences and 4 (7.3%) experienced sudden death. In conclusion, stent thrombosis most frequently presented as ST-elevation myocardial infarction, which was not fatal in 95%. There is a high risk of recurrence during the following 6 months.
