Risk of Atrial Fibrillation

Risk of Atrial Fibrillation 

  • When the heart doesn't beat right, blood pools in the heart
  • This leads to increased chance that a blood clot can form in the heart
  • This blood clot can move through the body up to the brain
  • The clot gets stuck and blocks blood from getting to the brain, causing a stroke.

How do we lower risk?

What can we do to decrease the chance of stroke? 

  • We can use a medication to decrease blood clot formation 
  • These medications are called anticoagulants or "blood thinners" 
  • Using this medication can decrease your risk of stroke by 60%
