RESUMEN

Propósito del trabajo: Determinar el impacto del balón intra-aórtico de contrapulsación en la mortalidad por choque cardiogénico postinfarto agudo del miocardio. Método: 292 pacientes con infarto agudo del miocardio ingresaron a la unidad de cuidados intensivos coronarios en el período comprendido de febrero de 2001 a febrero del 2003, de los cuales 40 cumplieron los criterios de inclusión y exclusión, posteriormente fueron divididos en 2 grupos: choque cardiogénico temprano y tardío, se les asignó al azar y de forma ciega a recibir tratamiento a base de inotrópicos aislados e inotrópicos más balón intra-aórtico de contrapulsación. Resultados: Se observaron diferencias significativas en ambos grupos en los valores de la presión en cuña de la pulmonar (20.4 ± 1.6 vs 24.4 ± 1.50, p = 0.0004) y el índice cardíaco (2.06 ± 0.7 vs 1.65 ± 0.18, p = 0.0002). El grupo de choque tardío presentó una mayor mortalidad (25.9% vs 61.5%, p ‹ 0.05), los pacientes que recibieron apoyo con balón mostraron una disminución en la mortalidad del 66% y 69% en choque temprano y tardío respectivamente. Conclusiones: El uso del balón intra-aórtico de contrapulsación en los pacientes que desarrollan choque cardiogénico post IAM disminuye la mortalidad, como coadyuvante con el uso de inotrópicos y angioplastía primaria.
