Cardiovascular Aging: Perspectives From Humans to Rodents

Area of Science:

• Cardiovascular aging research
• Human physiology
• Gerontology

Background:

• Cardiovascular diseases are a major health concern in aging populations.
• Understanding age-associated cardiovascular changes in healthy individuals is crucial for disease prevention.
• The Baltimore Longitudinal Study of Aging (BLSA) has studied cardiovascular structure and function over two decades.

Purpose of the Study:

• To quantify age-associated alterations in cardiovascular structure and function in healthy humans.
• To identify specific cardiovascular changes related to aging.
• To explore the interplay between lifestyle, cardiovascular disease, and aging.

Main Methods:

• Longitudinal study of community-dwelling volunteers (BLSA).
• Rigorous screening for clinical and occult cardiovascular disease.
• Characterization of lifestyle factors, including exercise habits.
• Assessment of resting cardiovascular structure, function, and reserve capacity.

Main Results:

• Identified specific age-related changes in resting cardiovascular structure and function.
• Characterized alterations in cardiovascular reserve capacity with advancing age.
• Provided insights into cardiovascular aging in healthy humans.

Conclusions:

• Aging induces distinct changes in cardiovascular structure and function.
• These changes in healthy aging may inform strategies to prevent cardiovascular diseases.
• Animal models offer mechanistic insights into human cardiovascular aging.
