Impacto de un sistema de evaluación de tiempos a la reperfusión en infarto agudo de miocardio con elevación del ST

espanolIntroduccion: El tratamiento del infarto con supradesnivel del ST (IAMCEST) es tiempo-dependiente, por lo que los centros con angioplastia primaria (ATCp) deben estar organizados para asegurar una rapida reperfusion. Objetivos: Evaluar el impacto de un sistema de evaluacion sistematica de los tiempos de reperfusion y feedback de resultados en la reduccion de las demoras. Material y metodos: Estudio observacional, prospectivo, realizado en 46 centros con ATCp 24/7 de la Iniciativa Stent-Save a Life! Argentina. Se incluyeron pacientes con IAMCEST sometidos a ATCp antes de las 12 h desde el inicio de los sintomas, asistidos entre marzo de 2016 y febrero de 2019. La poblacion se dividio en tres etapas consecutivas de 1 ano cada una desde la inclusion de cada centro. Resultados: Se incluyeron 3492 pacientes consecutivos (primer ano: 1482; segundo ano: 1166; tercer ano: 844). Se observo una reduccion significativa del tiempo puerta-balon (TPB) (68, 60 y 50 min; p Conclusiones: La implementacion de un programa puerta-balon (PPB) en centros con ATCp permitio reducir los tiempos al tratamiento. EnglishBackground: Treatment of patients with ST-elevation myocardial infarction (STEMI) is time-dependent; therefore centers with primary percutaneous coronary intervention (pPCI) capability should be organized to achieve rapid reperfusion. Objectives: The aim of this study was to assess the impact of a systematic evaluation of reperfusion times with periodic feedback of results in reducing delays to treatment. Methods: This was an observational, prospective study conducted in 46 centers with 24/7 pPCI capability participating in the Stent-Save a Life! Argentina Initiative. Patients with STEMI who underwent pPCI within 12 hours from the onset of symptoms were included from March 2016 to February 2019. The population was divided into three consecutive stages lasting one year each since the inclusion of each center in the Stent-Save a Life! Initiative. Results: A total of 3,492 patients were included (1st year: 1,482, 2nd year: 1,166, 3rd year: 844). There was a significant reduction in door-to-balloon (DTB) time (68, 60 and 50 min; p Conclusion: The implementation of a DTB program in centers with pPCI capability resulted in a significant reduction of treatment times.
