Incidence of Transient Ischemic Attack and Association With Long-term Risk of Stroke.

ABSTRACT:

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.

Objective

To determine population-based incidence of TIA and the timing and long-term trends of stroke risk after TIA.

Design, 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. A sample of TIA-free participants was matched to participants with first incident TIA on age and sex (ratio, 5:1).

Exposures

Calendar time (TIA incidence calculation, time-trends analyses), TIA (matched longitudinal
