<p>The third leading cause of death in the United States, stroke is an acute neurological event leading to death of neural tissues.
     Although the majority of strokes are ischemic strokes, meaning there is oxygen deprivation to the brain, almost 20% of strokes are
     hemorrhagic, resulting from bleeding into the brain. Stroke is a complex disorder and likely multigenic in nature, resulting from
     a combination of genetic and environmental factors. These well characterized risk factors that contribute to the incidence of stroke
     include hypertension, cardiac disease, sickle cell disease, hyperhomocysteinemia, family history of stroke and smoking.

<pre><code>&#x3C;p>ISGS aim is to perform a prospective genetic association study of ischemic stroke focusing on the hemostatic system. ISGS
is a 5-center case-control study of first-ever ischemic stroke cases and concurrent controls individually matched for age,
sex and recruitment site.
