The treatment of hypertension in older people and its effect on cognitive function
1Epidemiology Unit, London School of Hygiene and Tropical Medicine, UK.
Insights
Antihypertensive drug therapy significantly benefits older adults, reducing mortality and vascular events. Recent evidence shows concerns about adverse effects are unfounded, yet many older individuals with hypertension remain undertreated or inadequately controlled.
Area of Science:
- Gerontology
- Cardiology
- Pharmacology
Background:
- Established benefits of antihypertensive drug therapy in older populations.
- Meta-analyses show significant reductions in mortality, coronary heart disease, and stroke.
- High incidence of vascular disease underscores the importance of treatment.
Purpose of the Study:
- To address clinician concerns regarding adverse effects of antihypertensive drugs on cognition, mood, function, and quality of life in older adults.
- To highlight the discrepancy between established benefits and current treatment rates in elderly hypertensive patients.
Main Methods:
- Review of meta-analyses on antihypertensive drug therapy outcomes in older people.
- Examination of recent randomized controlled trials addressing safety concerns.
Main Results:
- Antihypertensive therapy demonstrates substantial benefits, including a 12% reduction in all-cause mortality, 20% in coronary heart disease, and 36% in stroke.
- Recent trial evidence indicates that concerns about adverse effects on cognition, mood, and function are not supported.
- Despite clear benefits, up to 50% of older adults with hypertension are untreated, and over 50% of treated individuals have inadequate blood pressure control.
Conclusions:
- The established benefits of antihypertensive drug therapy for older adults are significant and outweigh unsubstantiated concerns about adverse effects.
- There is a critical need to improve treatment initiation and management strategies for hypertension in the elderly population.
- Addressing undertreatment and inadequate control is essential to realize the full public health potential of blood pressure management in older individuals.
Abstract:
The benefits of antihypertensive drug therapy for older people have been clearly established. Meta-analysis suggests a 12% reduction in all-cause mortality, a 20% reduction in coronary heart disease and a 36% reduction in stroke. The absolute benefits of treatment are great due to the high incidence of vascular disease among older people. Clinicians may nevertheless have been deterred from initiating treatment because of concerns regarding adverse effects on cognition, mood, functional ability and quality of life. Recent evidence from randomised controlled trials suggests that these concerns are groundless. In the light of this evidence it is therefore disturbing that up to 50% of all older people with hypertension may remain untreated; and in over 50% of those who are treated, blood pressure may be inadequately controlled.
