This is a multi-center retrospective analysis of consecutive adult patients with cryptogenic stroke patients following a comprehensive workup for the underlying stroke etiology. Patients will be eligible for inclusion if the index stroke event occurred between 1/1/2016 and 06/30/2022.
This is an exploratory observational cohort study of existing registry-based clinical, laboratory, and radiographic data. There are multiple pre-specified hypotheses that will be tested using this data set, which include the entire cohort as well as planned subgroup analyses. The analyses center around patients with cryptogenic stroke (no clear stroke mechanism) but who are characterized by "potential embolic sources". These include but are not limited to: left atrial enlargement or dysfunction, left ventricular dysfunction /heart failure with reduced ejection fraction (HFrEF), patent foramen…
