The purpose of this study is to find risk factors for hemorrhagic stroke, specifically intracerebral hemorrhage (ICH). ICH, a type of bleeding into brain tissue, is a type of stroke that can result in death or disability in a large number of people. Our study hopes to identify a specific genetic risk factor that will help identify at risk individuals and target treatment strategies.
Our case-control study will enroll subjects with a spontaneous ICH in the Greater Cincinnati region. For each subject enrolled we will also enroll a healthy control subject(matched by age , race and gender). Both the cases and control will undergo the same interview and have blood drawn for genetic analysis. The cases will have a chart abstraction done on their event medical record and be contacted for 3 and 6 month follow up(short interview). The genetic sample will be genotyped using the Affymetrix 6.0 gene chip looking for SNPs of interest and to identify genetic variants associated with ICH. The most promising SNPs identified through this process will be replicated in the external cohort from Massachusetts General Hospital.
- Observation: Case Control
- Perspective: Prospective
- Sampling: Non-Probability Sample
This study will be limited to physician-reviewed cases of people who have had a hemorrhagic stroke, specifically an intracerebral hemorrhage, and live within a 100 mile radius of the University of Cincinnati.
This study will be limited to physician-reviewed cases of people who have had a hemorrhagic stroke, specifically an intracerebral hemorrhage, and live within a 100 mile radius of the University of Cincinnati and healthy volunteers who are randomly identified in the same 100 mile radius of the University of Cincinnati and have not had a hemorrhagic stroke. Participants will need to have blood samples obtained for DNA.
|Type||Measure||Time Frame||Safety Issue|
|Primary||The analysis of the presence of specific genetic markers associated with hemorrhagic stroke versus the control group.|
|Secondary||Analysis of risk factors such as age, race, gender, current smoking, heavy alcohol use, use of anticoagulants, diabetes, hemorrhagic stroke family history, hypertension, etc. in people with hemorrhagic stroke versus the control group.|
