Resumen

Introducción y objetivos: La evidencia del beneficio en el pronóstico a largo plazo de los stents farmacoactivos (SFA) de nueva generación es limitada, en especial en los pacientes con angioplastia primaria. El objetivo de este trabajo fue comparar el impacto en el pronóstico a largo plazo de la implantación de SFA frente a stents metálicos (SM) en pacientes del mundo real tratados con angioplastia primaria. Métodos: Estudio de cohortes en el que incluyeron 1.499 pacientes ingresados de forma consecutiva con diagnóstico de infarto agudo de miocardio con elevación del segmento ST y sometidos a angioplastia primaria entre enero de 2008 y diciembre de 2015. El 24,9% recibió un SFA. Mediante un análisis de emparejamiento por puntuación de propensión se obtuvieron 2 grupos de 262 pacientes emparejados según la implantación de SFA o SM. Resultados: Durante el seguimiento (mediana de 1.015 días), los pacientes que recibieron SFA tuvieron tasas más bajas de mortalidad por todas las causas (6,5 frente a 12,2%; p = 0,049), así como en el objetivo combinado de eventos adversos mayores (16,4 frente a 25,2%; p = 0,049) y un objetivo combinado orientado al paciente que incluía muerte por cualquier causa, infarto de miocardio y revascularización en el seguimiento (12,6 frente a 22,5%; p = 0,017). No se observaron diferencias en cuanto a trombosis definitiva del stent. Conclusiones: En nuestro registro, en una población del mundo real de pacientes consecutivos tratados con ICP primaria, la utilización de SFA frente a SM se asoció a una mayor supervivencia y una reducción de los eventos clínicos en el seguimiento a largo plazo, sin observar diferencias en la trombosis del stent.
