L'impact de la thérapie intensive de la tension artérielle sur les inquiétudes concernant les chutes: résultats longitudinaux de l'essai d'intervention sur la tension artérielle systolique (SPRINT).

Résumé (en anglais)

OBJECTIVES: Concern about falling is common among older hypertension patients and could impact decisions to intensify blood pressure therapy. Our aim was to determine whether intensive therapy targeting a systolic blood pressure (SBP) of 120 mm Hg is associated with greater changes in concern about falling when compared with standard therapy targeting an SBP of 140 mm Hg.

DESIGN: Subsample analysis of participants randomized to either intensive or standard therapy in the Systolic Blood Pressure Intervention Trial (SPRINT).

SETTING: Approximately 100 outpatient sites.

PARTICIPANTS: A total of 2313 enrollees in SPRINT; participants were all age 50 or older (mean = 69 y) and diagnosed with hypertension.

MEASUREMENTS: Concern about falling was described by the shortened version of the Falls Efficacy Scale International as measured at baseline, 6 months, 1 year, and annually thereafter.

RESULTS: Concern about falling showed a small but significant increase over time among all hypertension patients. No differences were noted, however, among those randomized to intensive vs standard therapy (P = .95). Among participants younger than 75 years, no increase in concern about falling over time was noted, but among participants aged 75 years and older, the mean falls self-efficacy score increased by .3 points per year (P < .0001). No differences were observed between the intensive and standard treatment groups when stratified by age (P = .55).

CONCLUSION: Intensive blood pressure therapy is not associated with increased concern about falling among older hypertension patients healthy enough to participate in SPRINT. J Am Geriatr Soc 68:614-618, 2020.
