New Insights into Blood Pressure Control for Intracerebral Haemorrhage.

New Insights into Blood Pressure Control for Intracerebral Haemorrhage. Front Neurol Neurosci. 2015 Nov;37:35-50 Authors: Manning LS, Robinson TG Abstract Although blood pressure (BP) levels may rise in the weeks preceding intracerebral haemorrhage (ICH), in contrast to findings in the ischaemic stroke population, the initial post-ICH BP is often much higher than the last pre-morbid level. Elevated BP is therefore common in acute ICH, often with markedly elevated levels, and is associated with poor outcomes, though the exact pathophysiological mechanisms remain unclear. The Antihypertensive Treatment of Acute Cerebral Haemorrhage (ATACH) trial and the INTEnsive blood pressure Reduction in Acute Cerebral haemorrhage Trial (INTERACT) demonstrated that early and intensive lowering of elevated BP in the acute ICH period is feasible and safe. Importantly, recent CT perfusion studies have shown that early, intense BP reduction does not reduce cerebral blood flow or promote cerebral ischaemia. The recent, large INTERACT2 trial confirmed the safety of early BP lowering in ICH and suggested that intensive target-driven BP reduction may improve outcomes, with a non-significant trend towards reduced death and major disability and a significant favourable shift of scores on the modified Rankin scale compared with guideline-based treatment. BP lowering in acute ICH may reduce haematoma growth, particularly when target levels are achieved early an...
