Gene Discovery for Warfarin-Related Intracerebral Hemorrhage
This is a prospective, longitudinal cohort study of spontaneous ICH. Subjects were recruited from among consecutive patients >= 55 years old who presented with primary hemorrhage to the Massachusetts General Hospital or one of our off-site collaborators from 1999 to 2010. Potential subjects were identified by screening lists of all admissions to the neurology and neurosurgery inpatient services. All patients underwent routine clinical evaluation, including history taking and physical examination, laboratory testing, and computed tomography of the brain.
