Stent Thrombosis in the Modern Era: Incidence, Outcome, and Predictive Factors

Incidence, predictors, and clinical outcomes of early stent thrombosis in acute myocardial infarction patients treated with primary percutaneous coronary angioplasty (insights from the University of Ottawa Heart Institute STEMI registry)

“…We found that early ST was associated with significantly higher inhospital and 30-day mortality, in keeping with the findings of previously published studies [18,19] found to be a predictor of ST, which was not the case in our study. The significant increase in the rate of minor bleeding in the early ST could be explained by the higher and longer use of anticoagulation post repeat revascularization.…”

“…We found that early ST was associated with significantly higher in‐hospital and 30‐day mortality, in keeping with the findings of previously published studies . Among the patients suffering early ST, mortality occurred in the ones who suffered ST after 24 hr.…”

“…matched patients in the two groups to assess the angiographic predictors of early ST. We found that the average stent diameter was significantly different in two groups, a finding consistent with a previous study [19]. We also noticed that patients with early ST had lower use of the intracoronary glycoprotein IIb/IIIa inhibitors.…”

The long term results of vertebral artery ostium stenting in a single center

“…This is in contrast with analyses after percutaneous coronary angioplasty and stenting which had shown an inverse relationship between vessel size and recurrent ischemic events on follow-up 34. A longer lesion means greater plaque burden and increased probability of smooth muscle cell proliferation and migration to the neointima, which may be one of the underlying mechanisms leading to the recurrent events.…”

Utilidad de la citometría de flujo en la determinación de microagregados plaquetarios en pacientes con stent tratados con clopidogrel

“…grel 75 mg/día+ácido acetil salicílico [AAS] 100 mg/día], la incidencia de trombosis en pacientes con un stent implantado continúa siendo del 0,5 al 3,3% de los casos[1][2][3][4][5] . En la mayoría de éstos la medicación se aplica de forma empírica, sin monitorizar el grado de efectividad antiplaquetaria del tratamiento, por lo que no suelen detectarse los pacientes noARTICLE IN PRESSCitometría de flujo para determinar microagregados plaquetarios…”
