In this retrospective analysis of over 170,000 patients with Afib, of the 18% who were at high risk of stroke (CHADS2 score of 3-6), only 42% of them were receiving anticoagulation with warfarin. The % on warfarin was not much different from those in low risk group (CHADS2 score of 0; 40% were on warfarin) or in the moderate risk group (CHADS2 score of 1-2; 44% were on warfarin). Only about a third of patients in each group received continuous warfarin for 6 months. This study highlights the inadequacies of treating high risk stroke patients with warfarin therapy, and the difficulties in keeping them on continuous therapy (abstract)
