[Stent thrombosis in the modern era: incidence, outcome and predictive factors].
Coronary stent thrombosis is a catastrophic complication of percutaneous coronary intervention. Its incidence is reported to be about 1%, though it can occur more frequently in high-risk patients, in high-risk lesions, and in multivessel procedures. We investigated the occurrence of stent thrombosis in 404 consecutive patients in a period when conventional and drug-eluting stents were both being used. We found an overall incidence of 2.23%, a mortality rate of 22.2%, and a non-fatal myocardial infarction rate of 66.6%. Predictors of stent thrombosis were acute myocardial infarction, multiple stent placement, poor ejection fraction, small stent diameter, the presence of residual dissection, and premature discontinuation of clopidogrel.
