The novel measurement is called left atrial strain. It uses speckle tracking echocardiography to measure the muscle function of the left atrium, one of the cardiac chambers. Investigators investigated whether patients with lower function of this chamber are at a higher risk of developing stroke from blood clots traveling to the brain. It is already known that patients with an irregular heart rhythm known as atrial fibrillation are at higher risk of these types of strokes. Investigators wanted to determine if there is a similar association in patients with normal heart rhythm but low left atrial strain.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': 'Patients presenting to the emergency department with FAST positive symptoms suspicious for an acute stroke.', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Emergency department presentation with FAST positive symptoms\n* Neuroimaging performed as part of stroke workup\n* Echocardiogram performed during index admission\n\nExclusion Criteria:\n\n* Any history of atrial fibrillation prior or during admission\n* Age below 18 years of age\n* No echocardiogram or echocardiogram images not of sufficient quality to perform left atrial strain analysis\n* At least moderate mitral regurgitation\n* ASD or PFO'}, 'identificationModule': {'nctId': 'NCT07102693', 'acronym': 'ASSISTANT', 'briefTitle': 'Left Atrial Strain Assessment in Ischemic Stroke Patients', 'organization': {'class': 'OTHER', 'fullName': 'Connolly Hospital Blanchardstown'}, 'officialTitle': 'Left Atrial Strain Assessment in Ischemic Stroke Patients: a Retrospective Case-control Study - the ASSISTANT Study', 'orgStudyIdInfo': {'id': 'CBH 024/23'}}, 'armsInterventionsModule': {'armGroups': [{'label': 'Patients with Acute Ischemic Stroke', 'description': 'Patients presenting to the emergency department with FAST positive symptoms who are proven to have acute ischaemic stroke on neuroimaging.'}, {'label': 'Patients without Acute Ischaemic Stroke', 'description': 'Patients presenting to the emergency department with FAST positive symptoms who do not have evidence of acute ischaemic stroke on neuroimaging and an alternative cause of their FAST symptoms is found'}]}, 'contactsLocationsModule': {'locations': [{'zip': 'D15 X40D', 'city': 'Dublin', 'state': 'Co.
