[Capillary blood circulation in middle-aged and elderly arterial hypertension patients]
Insights
Changes in skin capillary circulation in elderly patients with hypertension mirror those in healthy individuals. Lowering blood pressure by reducing cardiac output can worsen circulation, while reducing peripheral resistance improves it.
Area of Science:
- Cardiovascular Physiology
- Geriatric Medicine
- Hypertension Research
Context:
- Investigated elderly and old patients (60-89 years) with hypertensive disease and atherosclerotic (systolic) hypertension.
- Examined the relationship between central hemodynamics and skin capillary circulation in these patient groups.
- Compared circulatory changes in hypertensive patients to age-matched healthy individuals.
Purpose:
- To determine if hypertensive disease or systolic hypertension in the elderly alters skin capillary circulation uniquely.
- To understand the impact of hemodynamic changes on capillary circulation in older hypertensive populations.
Summary:
- Skin capillary circulation in elderly and old patients with hypertension showed no specific features compared to healthy controls of the same age.
- A decrease in arterial pressure due to diminished cardiac output frequently led to deteriorated capillary circulation.
- A hypotensive effect achieved by reducing total peripheral resistance generally improved capillary circulation.
Impact:
- Findings suggest that age-related circulatory changes in hypertension are not distinct from healthy aging.
- Highlights the importance of the mechanism of blood pressure reduction in managing capillary perfusion in hypertensive elderly patients.
- Provides insights into optimizing therapeutic strategies for hypertension in older adults to maintain microvascular function.
Abstract:
Eighty patients with hypertensive disease and sixty patients with atherosclerotic (systolic) hypertension of the elderly (60--70 years old) and old (78--89 years old) age groups were examined. Skin capillary circulation and the indices of central hemodynamics were studied. It was found that changes in capillary circulation in elderly and old patients with hypertensive disease or systolic hypertension had no specific features and were of the same character as those in healthy individuals of the same age. In decrease of arterial pressure as the result of diminished cardiac output deterioration of capillary circulation was quite frequently encountered. A hypotensive effect, which is attended with reduction of total peripheral resistance, leads as a rule to improvement of capillary circulation.
