Sex Differences in the Presentation, Care, and Outcomes of Transient Ischemic Attack: Results From the Ontario Stroke Registry.

Background And Purpose: Little is known about whether sex differences exist in the presentation, management, and outcomes of transient ischemic attack.

Methods: We conducted a cohort study of 5991 consecutive patients with transient ischemic attack admitted to 11 stroke centers in Ontario, Canada, between July 1, 2003, and March 31, 2008 and compared presenting symptoms, processes of care, and outcomes in women and men. We used linkages to administrative databases to evaluate mortality and recurrent vascular events within 30 days and 1 year of the initial presentation, with multivariable analyses to assess whether sex differences persisted after adjustment for age and comorbid conditions.
