Intensive vs Standard Blood Pressure Control in Adults 80?Years or Older: A Secondary Analysis of the Systolic Blood Pressure Intervention Trial.

ABSTRACT: OBJECTIVES:To evaluate the effect of intensive systolic blood pressure (SBP) control in older adults with hypertension, considering cognitive and physical function. DESIGN:Secondary analysis. SETTING:Systolic Blood Pressure Intervention Trial (SPRINT) PARTICIPANTS: Adults 80?years or older. INTERVENTION:Participants with hypertension but without diabetes (N = 1167) were randomized to an SBP target below 120?mm Hg (intensive treatment) vs a target below 140?mm Hg (standard treatment). MEASUREMENTS:We measured the incidence of cardiovascular disease (CVD), mortality, changes in renal function, mild cognitive impairment (MCI), probable dementia, and serious adverse events. Gait speed was assessed via a 4-m walk test, and the Montreal Cognitive Assessment (MoCA) was used to quantify baseline cognitive function. RESULTS:Intensive treatment led to significant reductions in cardiovascular events (hazard ratio [HR] = .66; 95% confidence interval [CI] = .49-.90), mortality (HR = .67; 95% CI = .48-.93), and MCI (HR = .70; 95% CI = .51-.96). There was a significant interaction (P?
