Summary

This summary is machine-generated.

Inpatient stroke testing for treatable causes increased over time, leading to fewer strokes of unknown origin. This trend is crucial for understanding and reducing stroke recurrence rates.

Area of Science:

Neurology
Cardiology
Public Health

Background:

Examined inpatient testing practices for acute ischemic stroke.
Focused on identifying stroke etiologies and treatable risk factors for recurrence.

Purpose of the Study:

To analyze trends in diagnostic testing for stroke workup.
To assess the association between increased testing and stroke etiology determination.

Main Methods:

Retrospective analysis of stroke cases from the Greater Cincinnati/Northern Kentucky Stroke Study (1993-2010).
Tracked evaluations for carotid stenosis and atrial fibrillation.
Recorded stroke etiology based on diagnostic testing and physician adjudication.

Main Results:

Increased use of extracranial artery and cardiac assessments over time (50% to 78%).
Significant rise in echocardiography utilization (57% to 83%).
Decreased proportion of strokes with unknown etiology (47% to 38%) and increased known causes.

Conclusions:

Stroke workup for treatable causes is more frequent.
Increased diagnostic intensity correlates with a reduction in cryptogenic strokes.
Further research is needed to confirm if this translates to decreased stroke recurrence at the population level.
