Why the study?

Does Transient Ischemic Attack (TIA) increase the long-term risk of stroke?

Population

Discussion

Implication

TIA remains associated with elevated stroke risk that has declined over time; leaves open drivers of improvement in contemporary cohorts.

Key Points

To investigate the incidence of transient ischemic attack (TIA) and its association with long-term stroke risk.
Population-based cohort study conducted from 1948 to 2017
Crude TIA incidence estimated at 1.19 per 1000 person-years
Comparison of stroke risk between TIA patients and matched controls without TIA.
Stroke risk significantly greater after TIA compared to controls
Lower stroke risk observed in the recent period (2000-2017) versus an earlier period (1948-1985)

Structured PICO

Does Transient Ischemic Attack (TIA) increase the long-term risk of stroke?

Population

Population-based cohort from 1948-2017

Intervention

Transient Ischemic Attack (TIA) exposure

Comparator

Matched control participants who did not have TIA

Outcome

Long-term risk of strokehard clinical

While TIA remains a significant risk factor for subsequent stroke, the long-term risk of stroke following a TIA has decreased in recent decades.
