To determine if up to a 3 week treatment period of simvastatin can improve the long-term outcome in subjects who have had an aneurysmal subarachnoid haemorrhage.
|
||
Protection of trial subjects |
All subjects were monitored whilst in hospital as part of clinical care. Biochemical papameters were recorded at baseline and between days 9-12, in addition subjects were reviewed regularly by the research team.
|
||
