Infarto agudo de miocardio con elevación del segmento ST en la Argentina. Datos del registro continuo ARGEN-IAM-ST

Background: The National ST-segment elevation Acute Myocardial Infarction (ARGEN-AMI-ST) registry carried out in 2015 provideddata on the reality of AMI in Argentina.Objective: The aim of this study was to present an updated report of the ARGEN-AMI-ST registry.Methods: This was a national, prospective, multicenter study. After the first phase of the ARGEN-AMI-ST survey, centers wereinvited to continue with the AMI registry including patients with up to 36-hour electrocardiographic STEMI evolutionResults: The analyzed population comprised 2,464 patients assisted in 78 centers. Mean age was 60±12 years and 80% were men.Preventable risk factors were: 45% smoking, 58% hypertension, 24% diabetes, 41% dyslipidemia and 11% history of coronary heartdisease. Eighty-eight percent of patients underwent reperfusion, and among them, 21% received thrombolytics and 89% percutaneouscoronary intervention. The delay from onset of symptoms to admission was 130 minutes (IQR 25-75: 60-305); physiciansreported delays to treatment in 49% of cases, with an impact on total ischemic times (TIT). In-hospital mortality was 8.7%. In themultivariate analysis, being treated in a center with hemodynamic availability was not independently associated with survival.Conclusions: Current data from the continuous AMI registry in Argentina are similar to those shown in the 2015 survey. Delays totreatment are important, especially due to the delay in patient consultation, which greatly impacts on TIT. Introducción: A través del Registro Nacional de Infarto Agudo de Miocardio (IAM) con Elevación del ST (ARGEN IAM-ST) realizadoen 2015 se conocieron datos de la realidad del IAM en Argentina; en esta ocasión, se presenta un reporte actual.Material y métodos: Estudio prospectivo multicéntrico, con alcance nacional. Luego de la primera fase de la encuesta ARGEN-IAMST,se invitó a los centros a continuar con el registro de IAM. Se incluyeron pacientes con IAM con elevación del segmento ST en elelectrocardiograma de hasta 36 horas de evolución.Resultados: La población analizada abarcó 2464 pacientes asistidos en 78 centros. La media de edad fue 60 ± 12 años y el 80% fuede género masculino. Los factores de riesgo prevenibles se distribuyeron del siguiente modo: tabaquismo 45%, hipertensión arterial58%, diabetes 24% y dislipidemia 41%. El 11% tuvo antecedente de enfermedad coronaria. El 88% recibió reperfusión; el 21% de estospacientes recibieron trombolíticos y al 89% se le realizó angioplastia. La demora
