Management of Atrial Fibrillation in Elderly Patients

Prioridad Crítica: Manejo de la Fibrilación Auricular

The American Heart Association recommends oral anticoagulation (Class I) in patients ≥75 years with atrial fibrillation, regardless of other risk factors 1, 2
The European Society of Cardiology prefers direct oral anticoagulants (DOACs) over vitamin K antagonists in eligible patients with atrial fibrillation 3
At 75 years, the risk of ischemic stroke without anticoagulation (2-5% annual) surpasses the risk of bleeding with anticoagulant treatment 1, 2
Age alone is not a contraindication for anticoagulation in high-risk patients with atrial fibrillation 1, 2

The European Society of Cardiology recommends rate control therapy in patients with atrial fibrillation as an initial strategy 3
Beta-blockers, diltiazem, verapamil, or digoxin are first-line drugs in patients with atrial fibrillation and left ventricular ejection fraction >40% to control heart rate 3
Rate control with chronic anticoagulation is the recommended strategy for most patients with atrial fibrillation 4

The American Heart Association recommends calculating CHA₂DS₂-VASc (age ≥75 years = 2 points automatically) 5
Renal function should be evaluated before initiating DOACs 5
Blood pressure measurement is crucial (hypertension control is critical to reduce the risk of intracerebral hemorrhage with anticoagulation) 1, 2
The American College of Cardiology prefers DOACs over warfarin (dabigatran, rivaroxaban, or apixaban) 5
If warfarin is used, the target INR is 2.0-3.0 (some experts recommend 1.6-2.5 in patients ≥75 years) 1, 2
Renal function should be reevaluated at least annually with DOACs 5

Anticoagulation should be continued indefinitely, even if rhythm control is achieved, since 70% of strokes occur in patients with subtherapeutic INR or those who discontinued anticoagulation 4
The need for anticoagulation should be regularly reevaluated, but in patients ≥75 years, the indication is permanent 6
The American Heart Association recommends that control of blood pressure is critical: it reduces both the risk of ischemic stroke and intracerebral hemorrhage complicating anticoagulation 1, 2
