title: Atrial fibrillation in the elderly: physicians' attitudes to anticoagulation.
abstract: The use of warfarin and aspirin for the primary prevention of stroke in elderly patients with atrial fibrillation (AF) is controversial. To establish current practice we circulated a questionnaire to 300 geriatricians (G) and 300 cardiologists (C). The response rates were 47% G and 51% C. Most physicians prescribed warfarin in AF associated with mitral stenosis (G vs C, 86% vs 89%, NS). Cardiologists were more likely to prescribe warfarin in AF associated with dilated cardiomyopathy (G vs C, 52% vs 86%, P < 0.01). A minority would prescribe warfarin in aortic valve disease and AF (G vs C, 37% vs 24%, P < 0.05) and lone AF (G vs C, 10% vs 26%, P < 0.01). Aspirin was favoured in aortic valve disease and lone AF. The cardiologists were less reluctant to use warfarin in the young and more likely to electrically cardiovert the young with chronic AF.
