Effect of Intensive Blood Pressure Control on Incident Stroke Risk in Patients With Mild Cognitive Impairment.

Although the SPRINT trial failed to show a reduction in stroke with intensive BP control for all subjects, those with a Montreal Cognitive Assessment score consistent with mild cognitive impairment at baseline had an association between intensive BP control and lower risk of incident stroke. Future trials of primary prevention of stroke may benefit from enrichment using baseline vascular biomarkers of elevated risk, such as mild cognitive impairment.
