Atherosclerosis worsens with age, affecting more coronary artery branches. However, the body
Area of Science:
- Cardiovascular research
- Gerontology
- Pathology
Context:
- Atherosclerosis is a progressive disease affecting arteries.
- Aging is a significant risk factor for cardiovascular diseases.
- Understanding age-related changes in atherosclerosis is crucial for prevention and treatment.
Purpose:
- To investigate the morphological changes in coronary atherosclerosis with advancing age.
- To assess the impact of age on intravascular platelet activation and lipid profiles.
- To evaluate the age-related changes in the body's resistance to oxidative stress.
Summary:
- Morphological aggravation of atherosclerosis in coronary arteries increases with age.
- Hemodynamically significant lesions and occlusions affect a greater number of basal coronary artery branches in older individuals.
- Aging does not alter intravascular platelet activation or lipid profiles but enhances resistance to oxidative stress.
Impact:
- Provides insights into the age-dependent progression of coronary atherosclerosis.
- Highlights the dissociation between structural arterial changes and certain physiological markers (platelets, lipids) with aging.
- Suggests an improved endogenous defense mechanism against oxidative stress in the aging population, potentially influencing therapeutic strategies.
Abstract:
The data obtained have shown that morphological aggravation of atherosclerosis in coronary arteries occurs with age; local hemodynamically significant lesions or their combination with occlusion are more widely spread, i.e. a greater number of basal branches of coronary arteries are affected. Age does not influence intravascular activation of platelets and lipid profile, but the ability of an organism to resist oxidative stress improves with age.
