Answer

Although hypertension is common in acute ischemic stroke and is associated with poor outcome, studies of antihypertensive treatment in this setting have produced conflicting results. A theoretical drawback of blood pressure reduction is that elevated blood pressure may counteract dysfunctional cerebral autoregulation from stroke, but limited evidence suggests that antihypertensive treatment in acute stroke does not change cerebral perfusion.
