STROKE RISK FACTORS
Atrial fibrillation (AF) is associated with a 5-fold increase in the risk of ischemic stroke.1 Left atrial appendage (LAA) closure reduces the risk of stroke in non-valvular AF (NVAF) patients who are seeking an alternative to oral anticoagulants.2,3
AF AND STROKE ARE OFTEN CONNECTED
Characteristics of strokes caused by AF1:
NEARLY 2x
HIGHER MORTALITY
RATE WITHIN 1 YEAR
