Resumen
Objetivo: Analizar la asociación entre enfermedades preexistentes, muerte y duración de la hospitalización en puérperas con síndrome respiratorio agudo grave (IRAG) por COVID-19. Método: Estudio retrospectivo y multicéntrico realizado con 1.526 registros elegibles de puérperas con clasificación final de IRAG por COVID-19, notificados en el SIVEP-Gripe entre 2020 y 2021. Resultados: La enfermedad cardiovascular preexistente se asoció con una mayor probabilidad de muerte, incluso después del ajuste estadístico (OR=2,60; IC95% 1,79–3,78; p<0,001). Aunque las mujeres con enfermedad cardiovascular presentaron una mayor duración de la hospitalización en el análisis no ajustado, esta asociación no se mantuvo en el modelo de regresión cuantílica. La necesidad de soporte ventilatorio y el uso de medicamentos durante la hospitalización se asociaron con una mayor duración de la estancia hospitalaria. Conclusión: La enfermedad cardiovascular preexistente se asoció con una mayor probabilidad de muerte, pero no permaneció asociada con la duración de la hospitalización después del ajuste. Los indicadores relacionados con la gravedad clínica se asociaron con una mayor duración de la estancia hospitalaria.
