Objetivos: Comparar o progn\u00f3stico da popula\u00e7\u00e3o chag\u00e1sica e n\u00e3o chag\u00e1sica submetida ao implante de MP e ressincronizador card\u00edaco.  M\u00e9todos: Estudo observacional, retrospectivo, que analisou coorte de pacientes submetidos a implante desses dispositivos, em centro terci\u00e1rio, de outubro 2007 a dezembro de 2017, comparando o grupo de pacientes chag\u00e1sicos com os n\u00e3o-chag\u00e1sicos. O m\u00e9todo n\u00e3o param\u00e9trico de Kaplan-Meier foi utilizado para calcular a sobrevida dos pacientes. O n\u00edvel de signific\u00e2ncia adotado na an\u00e1lise estat\u00edstica foi de 5%. O desfecho prim\u00e1rio foi a mortalidade por qualquer causa, enquanto os desfechos secund\u00e1rios foram a ocorr\u00eancia de interna\u00e7\u00e3o e o desfecho combinado interna\u00e7\u00e3o e morte.  Resultados: Um total de 911 pacientes foram inclu\u00eddos, sendo que 23,4% apresentavam CCh. Em an\u00e1lise de Cox ajustada por sexo e idade, a doen\u00e7a de Chagas (dCh) n\u00e3o esteve associada ao risco aumentado de morte (HR: 1,14, IC:95%, 0,86-1,51, p=0,365), interna\u00e7\u00e3o (HR: 0,79, IC:95%, 0,61-1,04, p=0,09) ou desfecho combinado morte e interna\u00e7\u00e3o (HR: 0,90, IC:95%, 0,72-1,12, p=0,49).  Conclus\u00f5es: A dCh n\u00e3o se associou ao aumento do risco de morte, interna\u00e7\u00e3o, ou desfecho combinado morte e interna\u00e7\u00e3o, mesmo ap\u00f3s ajuste para sexo e idade. Tais resultados se contrap\u00f5em aos de estudos pr\u00e9vios e sugerem modifica\u00e7\u00e3o da qualidade do cuidado ao paciente
