What is stroke

A stroke, also known as a cerebrovascular accident (CVA), cerebrovascular insult (CVI), occurs when blood flow is interrupted to part of the brain. Without blood to supply oxygen brain cells  begin to deteriorate and die. Depending on the region of the brain affected, a stroke may cause  serious effects including paralysis, speech impairment, loss of memory and reasoning ability, coma, or death.*

Increased Stroke Risk

People with atrial fibrillation have five times the risk of stroke.¹ 

Ischemic Stroke
Hemorrhagic Stroke

Stroke is typically more severe for patients with AF. 4

  • AF-associated ischemic strokes occlude a larger-sized intracranial artery, depriving a larger territory of the brain of blood flow5
  • Thirty-day mortality was greater in AF strokes than in non-AF strokes (25% versus 14%)5
  • Compared with the non-AF group, the AF patients demonstrate a poorer survival and more recurrences of stroke at their one year follow-up5


The size of the vascular territory affected by the stroke will determine the number and severity of concurrent sequelae.
