What is the relationship between blood pressure and stroke recurrence in patients with intracranial arterial stenosis?
The Relationship between blood pressure and stroke recurrence in patients with intracranial arterial stenosis has been studied in several clinical trials. In the Warfarin-Aspirin Symptomatic Intracranial Disease (WASID) Trial, researchers found that lower blood pressure was associated with an increased risk of stroke recurrence. Similarly, a subgroup analysis of the Chinese Intracranial Atherosclerosis (CICAS) Study found that high blood pressure increases the risk of poor outcome at discharge and 12-month follow-up in patients with symptomatic intracranial large artery stenosis and occlusions. The VERiTAS Study Group also found a higher stroke risk with lower blood pressure in hemodynamic vertebro-basilar disease. Overall, it appears that lower blood pressure is associated with an increased risk of stroke recurrence in patients with intracranial arterial stenosis.
