anticoagulant therapy in patients with nonrheumatic atrial
fibrillation and recent cerebral ischemia. N Engl J Med 1995;333:5-10.
Notes:
The relationship between the risk of stroke anti INR in
patients with atrial fibrillation treated with warfarin is
shown on this slide. The risk of stroke increases dramatically
when the INR falls below 2.0, although there appears to be
some protection when the INR is above 1.5.
