IMPORTANCE: Clinical evidence supports the beneficial effects of lowering blood pressure (BP) levels in community-living, robust, hypertensive individuals older than 80 years. However, observational studies in frail elderly patients have shown no or even an inverse relationship between BP and morbidity and mortality.
OBJECTIVE: To assess all-cause mortality in institutionalized individuals older than 80 years according to systolic BP (SBP) levels and number of antihypertensive drugs.
DESIGN, SETTING, AND PARTICIPANTS: This longitudinal study included elderly residents of nursing homes. The interaction between low (<130 mm Hg) SBP and the presence of combination antihypertensive treatment on 2-year all-cause mortality was analyzed. A total of 1127 women and men older than 80 years (mean, 87.6 years; 78.1% women) living in nursing homes in France and Italy were recruited, examined, and monitored for 2 years. Blood pressure was measured with assisted self-measurements in the nursing home during 3 consecutive days (mean, 18 measurements). Patients with an SBP less than 130 mm Hg who were receiving combination antihypertensive treatment were compared with all other participants.
MAIN OUTCOMES AND MEASURES: All-cause mortality over a 2-year follow-up period.
RESULTS: A significant interaction was found between low SBP and treatment with 2 or more BP-lowering agents, resulting in a higher risk of mortality (unadjusted hazard ratio [HR], 1.81; 95% CI, 1.36-2.41); adjusted HR, 1.78; 95% CI, 1.34-2.37; both P < .001) in patients with low SBP who were receiving multiple BP medicines compared with the other participants. Three sensitivity analyses confirmed the significant excess of risk: propensity score-matched subsets (unadjusted HR, 1.97; 95% CI, 1.32-2.93; P < .001; adjusted HR, 2.05; 95% CI, 1.37-3.06; P < .001), adjustment for cardiovascular comorbidities (HR, 1.73; 95% CI, 1.29-2.32; P < .001), and exclusion of patients without a history of hypertension who were receiving BP-lowering agents (unadjusted HR, 1.82; 95% CI, 1.33-2.48; P < .001; adjusted HR, 1.76; 95% CI, 1.28-2.41; P < .001).
CONCLUSIONS AND RELEVANCE: The findings of this study raise a cautionary note regarding the safety of using combination antihypertensive therapy in frail elderly patients with low SBP (<130 mm Hg). Dedicated, controlled interventional studies are warranted to assess the corresponding benefit to risk ratio in this growing population.
