Fibrinólisis primaria o secundaria

Toggle: English / Spanish


La fibrinólisis es un proceso corporal normal que impide que los coágulos sanguíneos que ocurren en forma natural crezcan y causen problemas.

La fibrinólisis primaria se refiere a la descomposición normal de los coágulos.

La fibrinólisis secundaria es la descomposición de los coágulos sanguíneos debido a un trastorno de salud, un medicamento u otra causa. Esto puede provocar sangrado intenso.

Nombres alternativos

Fibrinólisis primaria; Fibrinólisis secundaria


Los coágulos de sangre se forman en una proteína llamada fibrina. La descomposición de la fibrina (fibrinólisis) puede deberse a:

  • Infecciones bacterianas
  • Cáncer
  • Ejercicio intenso
  • Bajo azúcar en la sangre
  • Oxigenación insuficiente a los tejidos

El médico puede darle medicamentos para ayudar a que los coágulos sanguíneos se descompongan más rápidamente. Esto se puede hacer si un coágulo de sangre provoca un ataque cardíaco.
