RESUMEN
Introducción y objetivos: Hay muy poca evidencia sobre las tasas de trombosis del stent (TS) en pacientes que reciben tratamiento antiagregante plaquetario doble (TAPD) con ticagrelor o prasugrel. El objetivo de este estudio es analizar la incidencia y predictores de la TS tras un síndrome coronario agudo en pacientes que reciben TAPD con ticagrelor frente a prasugrel. Métodos: Se utilizaron datos del registro RENAMI (REgistry of New Antiplatelet therapy in patients with acute Myocardial Infarction), y se analizó en total a 4.123 pacientes con síndrome coronario agudo dados de alta con TAPD con ticagrelor o prasugrel en 11 centros de 6 países europeos. Se consideró como evento la TS confirmada en el primer año. Se realizó un análisis de riesgos competitivos mediante un modelo de regresión de Fine y Gray, siendo la muerte el evento competitivo. Resultados: Recibieron TAPD con ticagrelor 2.604 pacientes y con prasugrel, 1.519; 41 pacientes (1,10%) presentaron TS, con incidencias acumuladas similares entre ticagrelor (1,21%) y prasugrel (0,90%). Los predictores independientes de la TS fueron: la edad (sHR = 1,03; IC95%, 1,01-1,06), la elevación del segmento ST (sHR = 2,24; IC95%, 1,22-4,14), el antecedente de infarto de miocardio (sHR = 2,56; IC95%, 1,19-5,49) y la creatinina sérica (sHR = 1,29; IC95%, 1,08-1,54). Conclusiones: La TS es infrecuente en pacientes que reciben TAPD con ticagrelor y prasugrel. La edad avanzada, la elevación del segmento ST, el antecedente de infarto y la creatinina sérica son las variables que se asocian con mayor riesgo de TS
ABSTRACT
Introduction and objectives: There is little evidence on rates of stent thrombosis (ST) in patients receiving dual antiplatelet therapy (DAPT) with ticagrelor or prasugrel. The aim of this study was to analyze the incidence and predictors of ST after an acute coronary syndrome among patients receiving DAPT with ticagrelor vs prasugrel. Methods: We used data from the RENAMI registry (REgistry of New Antiplatelet therapy in patients with acute Myocardial Infarction), analyzing a total of 4123 acute coronary syndrome patients discharged with DAPT with ticagrelor or prasugrel in 11 centers in 6 European countries. The endpoint was definite ST within the first year. A competitive risk analysis was carried out using a Fine and Gray regression model, with death being the competitive event. Results: A total of 2604 patients received DAPT with ticagrelor and 1519 with prasugrel; ST occurred in 41 patients (1.10%), with a similar cumulative incidence between ticagrelor (1.21%) and prasugrel (0.90%). The independent predictors of ST were age (sHR, 1.03; 95%CI, 1.01-1.06), ST segment elevation (sHR, 2.24; 95%CI, 1.22-4.14), previous myocardial infarction (sHR, 2.56; 95%CI, 1.19-5.49), and serum creatinine (sHR, 1.29; 95%CI, 1.08-1.54). Conclusions: Stent thrombosis is infrequent in patients receiving DAPT with ticagrelor or prasugrel. The variables associated with an increased risk of ST were advanced age, ST segment elevation, previous myocardial infarction, and serum creatinine
