A stroke occurs when the blood supply to part of the brain is interrupted. Patients with an irregular heart beat (known as atrial fibrillation) are at increased risk of stroke. Preventing stroke in these patients is a key focus of our cardiovascular team. Boehringer Ingelheim developed the first non-vitamin K antagonist oral anticoagulant (NOAC) to protect patients with non-valvular atrial fibrillation against stroke, advancing anticoagulation care.
