Treatment of Hypertension in Complex Older Adults: How Many Medications Are Needed?

Abstract

Background: Many older adults with hypertension receive multiple antihypertensives. It is unclear whether treatment with several antihypertensive classes results in greater cardiovascular benefits than fewer antihypertensive classes. Objectives: We investigated (a) the longitudinal associations between treatment with ≥ 3 versus 1-2 classes and death and major adverse cardiovascular events (MACE) and (b) whether these associations varied by the presence of mobility disability. Methods: We included 6,011 treated hypertensive adults ≥65 from the Medical Expenditure Panel Survey (MEPS), a nationally representative community sample. Times to MACE and death were compared between those receiving ≥3 versus 1-2 classes using multivariable proportional hazards regression. We used inverse probability of treatment weighting to account for indication and contraindication bias. Results: There were no significant differences in the risk of mortality (hazard ratio [HR] = 0.96, p = .769) or MACE (HR = 1.10, p = .574) between the exposure groups, and there were no significant exposure × mobility disability interactions. Discussion: We found no benefit of ≥3 versus 1-2 antihypertensive classes in reducing mortality and cardiovascular events in a representative cohort of older adults, raising concern about the added benefit of additional antihypertensives in the real world.

Adherence problems in elderly patients with hypertension

“…Non-pharmaceutical treatment mainly involves: a diet to normalize body weight, reduction of sodium chloride intake, increased physical activity, and cessation of smoking [6]. As regards pharmaceutical treatment, it involves taking appropriate doses of medication following the prescribed protocol at all stages of treatment [7].…”
