A blood sample will be taken. This will be stored to measure circulating markers and DNA that will be assessed to see if they can help identify causes of stroke which can then also be targeted in the future to reduce the risk of stroke.
In addition to these blood tests we will use the clinical information that has been collected about you and your health for as part of your care or that which contributes to national audit data in stroke. This will include clinical findings from the doctors, nurses, therapists and other health professionals that are involved with your care either in your written or electronic record, results of routine blood tests, ECG’s and any imaging that is XRay’s, ultrasound scans, CT scans or MRI scans). You do not need to do anything for this; we can simply collect this information from your record with your permission.
Some individuals will need surgery to unblock a narrowing in one of the vessels in the neck that supplies the brain with blood, and it is thought that this is the cause of stroke. If you are one of these individuals, we would also like to ask you if at the time of your operation, any tissue taken away at that time we may use for research. We are requesting tissue that would be surplus to requirements of diagnosis and would normally be discarded. If we can store and use for research, linking with the patients other information this will help us understand the mechanisms of how this narrowing forms in the first place.
