PURPOSE Hypertension trials often exclude patients with complex health problems and lack generalizability. We aimed to determine if systolic blood pressure (SBP) in patients undergoing antihypertensive treatment is associated with 1-year changes in cognitive/daily functioning or quality of life (QoL) in persons aged ≥75 years with or without complex health problems. METHODS We analyzed data from a population-based prospective cohort study (Integrated Systematic Care for Older Persons [ISCOPE]) with a 1-year follow-up. Stratified by SBP level in the year before baseline, we used mixed-effects linear regression models to evaluate the change from baseline to 1-year follow-up in outcome measures (Mini-Mental State Examination [MMSE], Groningen Activity Restriction Scale [GARS], and EQ-5D-3L). We adjusted for age, sex, and baseline MMSE/GARS/EQ-5D-3L scores and stratified for complex health problems as a proxy for frailty. RESULTS Participant (n = 1,266) age averaged 82.4 (SD 5) years, and 874 (69%) were women. For participants undergoing antihypertensive therapy (1,057; 83.5%) and with SBP <130 mm Hg, crude cognitive decline was 0.90 points MMSE, whereas in those with SBP >150 mm Hg, it was 0.14 points MMSE (ie, 0.76-point less decline; for trend = .013). Complex health problems modified the association of SBP with cognition; the association was seen in those with antihypertensive treatment ( for trend <.001), not in those without ( for trend = .13). Daily functioning/QoL did not differ across the strata of SBP or antihypertensive treatment. CONCLUSIONS Participants aged ≥75 years undergoing antihypertensive treatment, with SBP ≥130 mm Hg compared to <130 mm Hg, showed less cognitive decline after 1 year, without loss of daily functioning or QoL. This effect was strongest in participants with complex health problems. More studies should be conducted to determine if there is a causal relation and to understand the mechanism of the association observed.
