[Prevention of pathological aging. The arterial hypertension example]

Area of Science:

• Gerontology
• Cardiovascular Medicine
• Pathology

Context:

• Traditional views suggested universal decline in bodily functions with age.
• Recent studies challenge this by excluding subjects with pre-existing conditions.
• This re-evaluation separates age-related changes from disease-induced impairments.

Purpose:

• To differentiate between normal aging processes and age-related diseases.
• To investigate the impact of disease, specifically heart disease, on age-related functional decline.
• To explore the role of arterial hypertension and new treatments in arterial aging.

Summary:

• Excluding heart disease from studies on cardiac output and aging revealed that the decline was disease-related, not inherent to aging.
• Fundamental aging mechanisms differ between age groups, even when maintaining similar function.
• Arterial hypertension is linked to vascular dementia and pathological aging, with treatments showing promise.

Impact:

• Revising the understanding of aging, separating natural decline from disease.
• Suggests that preventative strategies, particularly for hypertension, can modify the aging profile.
• New antihypertensive drugs offer potential benefits for arterial aging and related conditions.
