Key result
Warfarin therapy in elderly patients with atrial fibrillation achieved therapeutic INR in 51% of tests, with female gender and cognitive/functional impairment associated with supratherapeutic INR.

What are the outcomes and challenges of warfarin therapy for stroke prevention in community-dwelling elderly patients with atrial fibrillation?
In very elderly patients with atrial fibrillation, achieving therapeutic anticoagulation is feasible but complicated by cognitive and functional impairments, underscoring the need for caregiver support.
No takes yet. Share an insight, caveat, or question.
Elderly AF patients on warfarin need close INR monitoring for impairment-related supratherapeutic levels; leaves open optimal strategies in this population.
Lackie et al. (2002) conducted an observational in Atrial fibrillation (n=18). Warfarin therapy was evaluated on Therapeutic INR response. Warfarin therapy in elderly patients with atrial fibrillation achieved therapeutic INR in 51% of tests, with female gender and cognitive/functional impairment associated with supratherapeutic INR.
