Medical AIAtrial fibrillation
Atrial fibrillation sits at the intersection of stroke prevention and bleeding risk. The questions that recur are practical: who to anticoagulate, which agent, and how to weigh a borderline score against a real bleeding history. The tools and answers gathered here keep the reasoning, not just the number, in view.
Calculators in this area
A 7-point score (0 to 7) estimating the 2-day risk of stroke after a transient ischaemic attack, from age, blood pressure, clinical features, symptom duration, and diabetes. Higher scores predict higher early stroke risk, but current guidance increasingly favours urgent specialist assessment and imaging over the score alone.
A weighted score (0 to 9) that refines stroke risk in non-valvular atrial fibrillation beyond the older CHADS2 schema, adding vascular disease, age 65 to 74, and female sex. It identifies the low-risk patients who can safely avoid anticoagulation and stratifies everyone else.
A simple bedside score (0 to 9) estimating the 1-year risk of major bleeding in atrial fibrillation patients on antithrombotic therapy. Its main value is highlighting reversible bleeding risk factors, not vetoing anticoagulation in patients who need it.
