The proposed study will validate the clinical use of new biomarker blood tests to identify
blood components that may differentiate between diverse stroke etiologies and clinical
outcomes as listed below:
1. Differentiate between cardioembolic and large artery atherosclerotic ischemic strokes,
when hemorrhagic stroke is ruled out.
2. In cases of ischemic strokes of unknown or "cryptogenic" etiology, determine the ability
of biomarker blood tests to predict etiology between cardioembolic and large artery
atherosclerotic.
3. In cases of cardioembolic ischemic stroke, further differentiation of cardioembolic
ischemic strokes into those caused by atrial fibrillation (AF) and those not caused by
AF.
4. Differentiate "transient ischemic attacks" (TIAs) from acute ischemic strokes.
5. Differentiate TIAs from non-ischemic "transient neurological events" (TNE) with similar
symptoms.

---|---|---|---|---|
Other | Development of point of care testing for ischemic stroke, transient ischemic attack (TIA), and transient neurological events (TNE). | Investigate the ability to translate the primary and secondary objectives into platforms that may be used in acute ischemic stroke evaluation. | Up to 60 days. | |
Primary | Cardioembolic and large vessel stroke stiology | Determine the ability of ISCDX, a blood test, to differentiate between clinically diagnosed cardioembolic and large artery atherosclerotic ischemic stroke when hemorrhagic stroke is ruled out. | Up to 60 days. | |
Primary | TIA differentiation from non ischemic events (TNE). | Determine the ability of TIADX, a blood test, to identify clinically diagnosed TIAs and differentiate these events from controls, which include TNEs. TNEs represent patients presenting with clinical symptoms similar to a TIA such as migraines, seizures and syncope, which are non-ischemic transient neurological events (TNE). | Up to 60 days. | |
Secondary | Cryptogenic stroke | Determine the ability of ISCDX to categorize strokes of cryptogenic strokes, as either cardioembolic or large artery atherosclerotic when best practice clinical diagnostic testing cannot determine the cause, suggesting the best treatment pathway. | Up to 60 days. | |
Secondary | Atrial fibrillation and stroke | Determine the ability of ISCDX to further sub-classify strokes diagnosed as cardioembolic into those caused by atrial fibrillation and those not caused by atrial fibrillation, such as structural defects in the heart. | Up to 60 days. | |
Secondary | Stroke and TIA, differentiation | Determine the ability of the ISCDX and TIADX tests to differentiate between a TIA and an ischemic stroke, much in the manner that Acute Coronary Syndrome is now viewed as part of a spectrum of cardiovascular diseases. | Up to 60 days. |
