Objective: In previous studies involving older hypertensive adults, geriatric conditions with potential prognostic impact and outcomes of geriatric relevance (e.g., disability) remained largely unexplored. This study investigated predictors of all-cause mortality and incident disability in a real-world sample of older hypertensive outpatients undergoing comprehensive geriatric assessment. Methods: We analyzed data from the longitudinal HYPER-FRAIL pilot study, involving hypertensive outpatients ≥75 years undergoing comprehensive geriatric assessment, office, ambulatory and home blood pressure (BP) measurements. Predictors of long-term all-cause mortality and incident disability in basic activities of daily living (BADL) were assessed using multivariate Cox and logistic regression analyses, respectively. Results: Among 112 participants (mean age 81.2 years, 58% women, median follow-up 55 months), mortality was 25.9%. Baseline BADL disability, impaired physical performance and frailty independently predicted mortality. Stratified analyses showed that higher BP was associated with increased mortality risk only in patients with preserved autonomy in instrumental activities of daily living (IADL). Among those with IADL disability, office diastolic BP
