Comparison of Two Argentine Registries on Myocardial Infarction: the 2011 SCAR Registry and the 2015 AR GEN -IA M-ST Registry

Background: The aim of this study was to compare patients with ST-segment elevation myocardial infarction (STEMI) included incenters participating of two registries in Argentina.Methods: STEMI patients included in the 54 centers participating in the SCAR (2011) registry and in the ARGEN-IAM-ST (2015)registry were compared.Results: A total of 676 STEMI patients were analyzed: 222 in the SCAR registry and 454 in the ARGEN-IAM-ST registry. There wereno significant differences in age and sex. The use of fibrinolytic agents was significantly lower and the use of primary percutaneouscoronary intervention was significantly increased. The incidence of cardiogenic shock was 50% lower. There were no differences inmortality and reinfarction during hospitalization.Conclusions: The indication of primary percutaneous coronary intervention increased and the use of fibrinolytic agents decreased.Cardiogenic shock decreased significantly in the last 5 years without significant changes in in-hospital mortality. Objetivos: Comparar pacientes con infarto agudo de miocardio con elevación del segmento ST (IAMCEST) incluidos en centrosparticipantes de dos registros argentinos.Material y métodos: Se compararon pacientes con IAMCEST incluidos en 54 centros que participaron tanto en el registro SCAR(2011) como en el ARGEN-IAM-ST (2015).Resultados: Se analizaron 676 pacientes con IAMCEST; 222 del SCAR y 454 del ARGEN-IAM-ST. No hubo cambios significativos enla edad y el género. Se observó una reducción significativa en el uso de fibrinolíticos, con un incremento de la angioplastia primaria.El shock cardiogénico se redujo a la mitad. No hubo diferencias en la mortalidad y de reinfarto durante la hospitalización.Conclusiones: Se observó una mayor indicación de angioplastia primaria y una disminución en el uso de fibrinolíticos. El shock cardiogénicose redujo significativamente en los últimos 5 años, sin cambios significativos en la mortalidad hospitalaria.
