Patients will be asked to revisit the study unit after 3 months and they will be interviewed and clinically examined again. Another blood sample will be taken then. Thereafter, patients will be contacted by telephone annually for 10 years, or depending on preferences and local practices, study visits can also be organized.
What is done with the blood samples?
With the blood samples, we aim to find new abnormalities in coagulation and e.g. markers of inflammation or dysfunction of the inner layer of arteries, as well as genetic abnormalities that may be involved in cryptogenic stroke. Before analyses, samples will be processed according to a standardized protocol, frozen, and stored anonymously.
