Also under development is a multi-protein test using mass spectrometry (MS). This test will provide TIA results within an hour or two for a fraction of the price of neuroimaging. With guidance provided by this test at their disposal, physicians can inform patients whether they can go home safely or whether they need further testing. The right patients will receive the right treatment, reduce unwarranted imaging risks and costs, and reduce the burden of stroke. The Heart and Stroke Foundation will work to ensure that physicians, allied healthcare providers, the public and other stakeholders are aware of the outcomes and clinical impacts of this project.\n\nFurther, work is being done to establish the mechanisms to develop a strong phenotype for TIA that includes medical imaging (MRI), cardiac monitoring, cognitive assessments, and surveillance of health outcomes for extended periods of time.', 'detailedDescription': 'Patients who fulfill all inclusion and none of the exclusion criteria after giving informed consent will be enrolled in the Validation study.\n\nAt enrollment, patients will receive a stroke nurse assessment in the Emergency Department (ED) and clinical information documented on an ACVS Assessment Form/SpecTRA Case Report Form. Patients will provide 6 mL of blood drawn into a purple-top EDTA tube that will be processed for proteomic analyses. These blood draws may or may not occur with the standard-of-care blood draw in the ED or stroke unit. Clinical orders include medical imaging (MRI +/- CT/CTA), cardiac monitoring (24hr +/- extended event monitoring). Patients will be referred by the attending ED physician to a stroke clinic for neurological consultation within 48 hours - 7 days, whereby diagnosis of (i) possible ACVS; (ii) definite ACVS or (iii) mimic will be made. At the stroke clinic a cognitive screening test will be administered either as part of usual clinical care by treating physicians, nurses, or a study coordinator. A re- assessment will be repeated at 90 days by phone. MRI will be reviewed initially for clinical interpretation at the neurological consultation for evidence of brain ischemia (DWI+) and later by neuro-radiologists for definitive diagnosis in study purposes. Final adjudication of TIA and aetiology will be done by the non-blinded principal investigators at each site based on diagnostic results plus 90-day and up to 2-year outcomes.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '19 Years', 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': 'The study population includes individuals presenting to the hospital ED or stroke clinic with symptoms suggesting mild ACVS who would be referred to the outpatient stroke clinic.
