Patients with acute brain injury are at risk for complications such as increased pressure in the brain (intracranial pressure (ICP)), decreased blood flow, bleeding, and brain swelling (cerebral edema). Several studies have suggested that high blood pressure is associated with a worsening outcome possibly due to an increased rate of continued bleeding or rebleeding, as well as increased brain swelling (cerebral edema). High systemic (body) blood pressure (SBP) may also increase the risk of ongoing bleeding. Therefore lowering the blood pressure (BP) is critical, as continued bleeding occurs most frequently in patients with high BP.
