INTRODUCTION: Orthostatic hypotension is a common condition associated with an increased mortality risk. This study investigates this association specifically in geriatric outpatients and additionally focuses on the duration and magnitude of orthostatic hypotension.
METHODS: In this observational prospective cohort study with geriatric outpatients from the Amsterdam Ageing cohort, we differentiated orthostatic hypotension in early orthostatic hypotension (EOH) and delayed/prolonged orthostatic hypotension (DPOH). The magnitude of drop in both SBP and DBP after either 1 or 3 min was quantified. Mortality data was obtained from the Dutch municipal register. Cox proportional hazard models were used to determine the association between orthostatic hypotension and mortality, adjusted for sex and age (model 1), additionally adjusted for orthostatic hypotension-inducing drugs + SBP (model 2) and the presence of cardiovascular disease and diabetes (model 3). Stratified analyses in patients with geriatric deficits were performed.
RESULTS: We included 1240 patients (mean age 79.4 ± 6.9 years, 52.6% women). Prevalence of orthostatic hypotension was 443 (34.9%); 148 (11.9%) patients had EOH and 285 (23%) DPOH. DPOH was associated with a higher mortality risk [hazard ratio, 95% CI 1.69 (1.28-2.22)] whereas EOH was not associated with mortality risk. This association did not differ in patients with geriatric deficits. Furthermore, the magnitude of drop in both SBP and DBP was associated with a higher mortality risk.
CONCLUSION: The presence of DPOH and the magnitude of both systolic and diastolic orthostatic hypotension are related to an increased mortality risk in geriatric outpatients. Whether the duration of orthostatic hypotension and magnitude of the drop in blood pressure is causally related to mortality risk or whether it is a sign of decreased resilience remains to be elucidated.
