Atrial Fibrillation Statistics

Atrial Fibrillation Statistics

Atrial fibrillation affects 3.0% of US adults aged 65 and older, yet it carries a stroke risk that rises about 5 times and drives roughly 1 in 4 strokes. Learn why global cases are projected to reach 84 million by 2030 and how modern anticoagulants such as DOACs can cut stroke risk by about 64% while also lowering major bleeding compared with warfarin.

Atrial fibrillation is present in about 3.0% of US adults age 65 and older and its lifetime risk is 9.1% for people age 55, yet the care gap is still wide, with guideline recommended anticoagulation missing in real world practice. Stroke is the major consequence, since AF is linked to roughly 1 in 4 cardioembolic strokes and increases stroke risk by about 5 times. With projections reaching 84 million people worldwide by 2030, these figures raise a clear question about who gets protected and who does not.
