This is a biobank study — a research project that collects and stores biological samples (mainly blood) from people with stroke, their relatives, and healthy people without stroke. Researchers will use these samples to study the genes and markers that may cause stroke and hardening of the arteries, helping doctors better understand why some people have strokes and how to prevent them in the future.
Stroke and blood vessel disease run in families and have genetic causes that doctors don't fully understand yet. By collecting samples from many people and studying them together, researchers hope to discover new genetic risk factors and biomarkers that could lead to better prevention and treatment strategies.

If you join, you would be asked to donate a one-time blood sample (about 30 milliliters, or 2 tablespoons). If you're having a medical procedure like a carotid stent (a tube placed in an artery), researchers may also collect a tiny tissue sample during that routine procedure. Some participants may have other samples collected, such as cerebrospinal fluid or a saliva sample. Your samples will be frozen and stored for future research studies on genes and biomarkers related to stroke.
