Afterload

Afterload graphs

Systemic vascular resistance index (SVRI)

  • If the afterload (SVRI) is increased, the heart must pump with more
  • power to eject the same amount of blood as before.
  • The higher the afterload, the less the cardiac output.
  • The lower the afterload, the higher the cardiac output.

If the afterload exceeds the performance of the myocardium, the heart may decompensate.
