[Treatment of hypertension in the aged]
Insights
Treating hypertension in elderly patients, especially those over 80, can lower cardiovascular deaths. Gradual blood pressure reduction and specific drug choices are key for geriatric hypertension management.
Area of Science:
- Geriatric Medicine
- Cardiology
- Pharmacology
Context:
- Hypertension management in the elderly is complex due to age-related physiological changes.
- Previous studies show reduced cardiovascular mortality in elderly hypertensives, primarily from cerebrovascular events.
- Limited data exists on treating uncomplicated hypertension and isolated systolic hypertension in patients over 80.
Purpose:
- To review the specific pathophysiological changes in elderly patients that influence hypertension treatment.
- To discuss the gradual reduction of blood pressure over weeks for geriatric hypertensives.
- To evaluate the suitability of different antihypertensive drug classes in the elderly population.
Summary:
- Age-specific changes like declining renal and cardiac performance, altered cerebral blood flow autoregulation, and reduced baroreceptor function impact hypertension management in older adults.
- Gradual blood pressure reduction over several weeks is recommended for geriatric patients.
- Antihypertensive medications with natriuretic or vasodilative properties are considered more beneficial, while those causing potassium loss, sympathetic depression, or negative inotropism are less favorable.
Impact:
- Highlights the need for tailored hypertension treatment strategies in the elderly.
- Informs clinical practice regarding the careful selection and titration of antihypertensive medications in older adults.
- Emphasizes the importance of considering age-related physiological changes for effective and safe hypertension management in geriatric populations.
Abstract:
Previous studies carried out on the treatment of hypertension in the elderly patient indicate that, in this group of patients, antihypertensive treatment can reduce cardiovascular mortality mainly by reducing mortality from cerebrovascular diseases. To date, the success of hypertensive treatment in over-80-year-olds with uncomplicated hypertension, and patients with isolated systolic hypertension, has not been documented. In the treatment of the elderly patient, age-specific pathophysiological changes need to be taken into account. Such changes are deteriorating renal performance, increased vasoconstriction, decreasing baroreceptor function, declining cardiac performance, and changes in the autoregulation of cerebral blood flow. For this reason, in geriatric hypertensives, the blood pressure should be reduced gradually over a period of weeks. Antihypertensive drugs with a natriuretic or vasodilative effect are pathophysiologically meaningful, while substances that result in a loss of potassium, depression of the sympathetic nervous system and negative inotropism are not so favorable.
