Five-Year Prognosis of TIA and TGA Patients in Finland

29.4% of patients with a transient ischemic attack (TIA) experienced a recurrent stroke within five years, compared to 7.1% of patients with transient global amnesia (TGA). This dataset contains supplementary material for a study of 349 patients diagnosed at Kuopio University Hospital in 2017, tracking 5-year outcomes via national registers. The research was authored by figshare admin karger and published on figshare in 2026.

Use Cases

• Predicting stroke risk after a TIA based on the ABCD2 score mentioned in the description
• Comparing long-term mortality rates between TIA and TGA patient cohorts
• Studying the correlation between index event type and subsequent cardiovascular events
• Analyzing the recurrence rates of TIA within a five-year follow-up period

Strengths

• Data is linked to national registers (Findata), likely ensuring comprehensive outcome tracking.
• The study reports specific, quantified 5-year risks for stroke (29.4%), recurrent TIA (29.0%), and mortality (25.9%) for the TIA cohort.
• Includes a comparison group of 56 patients with TGA, providing a clinical contrast.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is very small at 20.8 KB, indicating limited scope and likely summary-level data.
