Relationship between blood pressure and stroke recurrence in patients with intracranial arterial stenosis.
BACKGROUND Many clinicians allow blood pressure to run high in patients with intracranial stenosis to protect against hypoperfusion. We sought to determine whether higher blood pressure decreases the risk of stroke in these patients. METHODS AND RESULTS Data on 567 patients in the Warfarin-Aspirin Symptomatic Intracranial Disease (WASID) trial were analyzed. Time to ischemic stroke and stroke...
متن کاملRelationship between longitudinal changes in blood pressure and stroke incidence.
The relationship of changes in blood pressure with time to stroke incidence was examined on members of the Adult Health Study sample who have participated in biennial clinical examinations at the Radiation Effects Research Foundation since their inception in 1958. The regression coefficient of blood pressure regressed on time (the increase in blood pressure per cycle) was used as an index of th...
متن کاملInvestigation of sympathetic mechanism of inverse relationship between scalp and leg blood flow with increasing intracranial pressure in the rabbit
Intracranial pressure (ICP) is one of most important factors in determining health and function of cerebroscular system. However the methods of measuring ICP are usually invasive . In an attempt to find a noninvasive method to assess ICP, in previous study web found a reverse relationships between changes in ICP and blood flow in scalp (SBF) and leg skin (LSBF) . In this study the role of sympa...
متن کاملRelationship Between Hyperacute Blood Pressure and Outcome After Ischemic Stroke
Background and Purpose—High blood pressure (BP) is associated independently with poor outcome after acute ischemic stroke, although in most analyses “baseline” BP was measured 24 hours or more postictus, and not during the hyperacute period. Methods—Analyses included 1722 patients in hyperacute trials (recruitment 8 hours) from the Virtual Stroke International Stroke Trial Archive (VISTA) Colla...
متن کاملDoes lowering blood pressure prevent recurrent stroke?
Question In patients with a history of stroke or transient ischaemic attack, can further stroke be prevented by lowering blood pressure, even when it is not elevated? Commentary Rationale for the trial About one in five stroke survivors suffer another stroke in the five years after the initial incident. 1 Blood pressure is related in a continuous manner to the risk of an initial stroke, but man...
