A sample of TIA-free participants was matched to participants with first incident TIA on age and sex (ratio, 5:1).Įxposures Calendar time (TIA incidence calculation, time-trends analyses), TIA (matched longitudinal cohort). Objective To determine population-based incidence of TIA and the timing and long-term trends of stroke risk after TIA.ĭesign, Setting, and Participants Retrospective cohort study (Framingham Heart Study) of prospectively collected data of 14 059 participants with no history of TIA or stroke at baseline, followed up from 1948-December 31, 2017. Importance Accurate estimation of the association between transient ischemic attack (TIA) and risk of subsequent stroke can help to improve preventive efforts and limit the burden of stroke in the population.
