Summary
Brief summary
The purpose of the study is to determine whether lowering high blood pressure levels after the start of a stroke caused by bleeding in the brain (intracerebral haemorrhage) will reduce the chances of a person dying or surviving with a long term disability. The study will be undertaken in two phases: a vanguard phase in 400 patients, to plan for a main phase in 2000 patients.
