RESUMEN
RESUMEN Introducción y

objetivos:

El alta hospitalaria temprana (dentro de las primeras 48 horas) en pacientes con infarto agudo de miocardio con elevación del segmento ST (IAMCEST) tratados con angioplastia coronaria primaria con stent (ATCp) ha sido adoptada en países desarrollados. Sin embargo, su implementación en Sudamérica ha sido dispar. Material y

métodos:

Estudio piloto de intervención no controlado, argentino, de pacientes con IAMCEST de bajo riesgo tratados con ATCp, para evaluar tasa de alta temprana y comparar la incidencia de eventos cardiovasculares adversos mayores (MACE) con la que ocurre en pacientes externados en forma no temprana.

Resultados:

Desde 2013 hasta 2021 se trataron con ATCp 320 pacientes con IAMCEST, de los que 158 fueron de bajo riesgo. Alta temprana en 63,9% (IC 95% 55,9-71,4%). La diabetes (OR 0,31; IC 95% 0,12-0,83) y el IAMCEST anterior (OR 0,34; IC 95% 0,16-0,69) se asociaron en forma independiente con menor probabilidad de alta temprana. Durante una mediana de seguimiento de 27,2 meses, la razón de tasas de incidencia de MACE entre los grupos de alta temprana y no temprana fue de 0,77 (IC 95 % 0,25-2,58; p = 0,61). Las variables asociadas de forma independiente con MACE fueron la revascularización completa (HR 0,18; IC 95% 0,03-0,95) y el tiempo de fluoroscopía (HR 1,02; IC 95% 1,01-1,05). No hubo diferencias significativas en las complicaciones del acceso vascular, las tasas de reingreso a 30 días y sobrevida global entre los grupos.

Conclusiones:

El alta temprana en pacientes con IAMCEST de bajo riesgo tratados con ATCp puede ser factible incluso en países en desarrollo, sin aumento significativo de la morbimortalidad.
ABSTRACT
ABSTRACT Background and

objectives:

Early discharge (within the first 48 hours) in patients with ST-segment elevation myocardial infarction (STEMI) managed with primary percutaneous coronary intervention (PCI) with stenting is a strategy that has been adopted in developed countries. However, its implementation in South America has been uneven.

Methods:

We conducted an uncontrolled intervention pilot study on low-risk STEMI patients managed with primary PCI to evaluate the early discharge rate and compare the incidence of major adverse cardiovascular events (MACE) with those occurring in patients discharged later.

Results:

Of 320 STEMI patients managed with primary PCI from 2013 to 2021, 158 were low-risk patients and 63.9% (95% CI 55.9-71,4%) of them were discharged early. Diabetes (OR 0.31, 95% CI 0.12-0.83), and anterior wall STEMI (OR 0.34, 95% CI 0.16-0.69) were independently associated with lower probability of early discharge. During a median follow-up period of 27.2 months, the incidence rate ratio of MACE between the early discharge and non-early discharge groups was 0.77 (95% CI 0.25-2.58; p = 0.61). The variables independently associated with MACE were complete revascularization (HR 0.18, 95% CI 0.03-0.95) and fluoroscopy time (HR 1.02, 95% CI 1.01-1.05). There were no significant differences in vascular access complications, 30-day readmission rate and overall survival between groups.

Conclusions:

Early discharge in low-risk STEMI patients managed with primary PCI may be feasible even in developing countries, without significantly increasing morbidity and mortality.
