World Thrombosis Day

Know Atrial fibrillation

Atrial fibrillation (AFib) is a common type of arrhythmia, or irregular heartbeat. Because the heart beats and contracts irregularly, blood flow may slow or pool and cause the formation of a clot.
 
A blood clot that forms as a result of AFib is an example of arterial thromboembolism. If that clot breaks free, it can lodge in an artery, travel to the brain and result in a stroke.
 
Persons with AFib are at greater risk for stroke and are estimated to account for 15 percent of the 15 million strokes that occur worldwide every year.12,13
 
AFib-related stroke can be particularly dangerous. Patients are twice as likely to be bedridden and more likely to die compared to patients with non-AFib-related stroke.14
 
Just as every person being admitted into hospital has the right to a VTE risk assessment, everyone has the right to be evaluated for AFib. As a first step, have your pulse checked for an irregular heartbeat. An electrocardiogram (EKG or ECG) may be ordered to detect or confirm AFib.
 
AFib is often present without any signs or symptoms. That’s why early identification and management is critical.
 
Risk Factors for afib
  • Congestive heart failure
  • High blood pressure
  • Age of 65 or older
  • Diabetes
  • Stroke (prior), TIA, or thromboembolism
  • Vascular disease
  • Sex category (female > risk)
Take Action
  • Talk with a healthcare professional about AFib and ask to have your pulse checked for an irregular heartbeat.
  • If you are a healthcare professional, take initiative and evaluate your patients for AFib/arrhythmia risk.

* Based on the CHA2DS2VASc prediction score which estimates risk of stroke in patients with AFib
