Elevated Admission Blood Pressure and Stroke Severity in Acute Ischemic Stroke: The Bergen NORSTROKE Study

Abstract

Our study showed an inverse association between elevated BP and stroke severity on admission, where elevated BP was associated with mild stroke and lack of elevated BP was associated with severe stroke. This could be explained by a protective effect of elevated BP in the acute phase of ischemic stroke, although the absence of association between elevated BP and favorable outcome argues against this hypothesis.
