Does high or low blood pressure affect poor outcome in patients in the International Stroke Trial?
Both high and low blood pressure are independent prognostic factors for poor outcomes in stroke patients.
Both high blood pressure and low blood pressure were independent prognostic factors for poor outcome, relationships that appear to be mediated in part by increased rates of early recurrence and death resulting from presumed cerebral edema in patients with high blood pressure and increased coronary heart disease events in those with low blood pressure. The occurrence of symptomatic intracranial hemorrhage within 14 days was independent of SBP.
