Characteristics and outcome of angiographically confirmed stent thrombosis.
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.
