Background and study aims
Stroke is a serious, life-threatening medical condition that usually happens when a blood clot or haemorrhage cuts of the blood supply to an area of the brain. Symptoms vary according to how much of the brain is affected and where in the brain the stroke occurs, but includes paralysis, muscle weakness and speech difficulties. A stroke can also have an impact on the sufferers emotions and can lead to anxiety, depression and personality changes. It is thought that lowering blood pressure quickly after the stroke could have a beneficial effect on a patient’s recovery. Therefore, this study aims to find out whether giving patients who are suspected of having a stroke, a 5mg transdermal glyceryl trinitrate (GTN) patch (a commonly used drug in patients with heart disease) as soon as possible after stroke, and then daily for the next three days, improves outcome.
Who can participate?
Adult patients presenting to paramedics as having a stroke. The stroke should have occurred no more than 4 hours ago and the patients systolic BP >=120 mmHg
What does the study involve?
Participants are randomly allocated into one of two groups. Those in group 1 are given GTN patches for 4 days. Those in group 2 are given sham (dummy) patches for 4 days. The patches are unmarked and are covered with a gauze dressing so that participant, relatives and staff who are not putting the patches on don’t know what treatment has been given. The paramedic and hospital staff putting the patch on do know what treatment the patient has. Paramedics obtain consent and put the first patch on, either in the participant’s home or in the ambulance, before they take the patient to the hospital. The participant has all the care they would normally get for their stroke. In addition, they have a second CT scan on Day 2. They are telephoned 3 months and then 1 year after their stroke and asked various structured questions to determine their recovery. When settled in hospital, participants may be asked to agree to some extra procedures or give extra blood samples for research by a member of the research team. Participants do not need to take part in any of this additional research.
