Management of acute ischemic stroke with IV unfractionated heparin is subject to debate. The authors evaluated patient-related and institutional factors influencing its use in 42 hospitals. Cardioembolic stroke type, carotid stenosis, atrial fibrillation, and treatment in stroke units or intensive care units significantly increased the probability of use. However, there are large unexplained variations in IV heparin use among hospitals.
