Title: Intensive Versus Standard Blood Pressure Lowering to Prevent Functional Decline in Older People
Brief Summary: This randomized clinical trial examines if lowering and maintaining 24-hour ambulatory systolic blood pressure to \<130 mmHg (intensive control) versus \<145 mmHg (standard control) slows/halts the progression of deterioration of mobility and cognitive function linked to white-matter disease (also known as white-matter hyperintensity or WMH) in patients with normal or mildly impaired mobility and cognition in subjects with detectable cerebrovascular disease (\>0.5% WMH fraction of intracranial contents). The study patients will be enrolled and randomized to one of two levels of ambulatory blood pressure control (intensive to achieve a goal 24-hour systolic blood pressure of \< 130 mmHg or standard to achieve a goal 24-hour systolic blood pressure of \< 145 mmHg) for a total of 36 months.
