Blood vessel ageing and vascular memory

Area of Science:

• Cardiovascular Science
• Gerontology
• Preventive Medicine

Background:

• Aging blood vessels exhibit structural and functional decline.
• Diet and modifiable risk factors significantly impact vascular aging.
• Clinical assessments like arterial stiffness and ankle-brachial index evaluate vascular health.

Purpose of the Study:

• To explore the concept of vascular age and its modifiable determinants.
• To investigate the impact of interventions on vascular age and cardiovascular risk.
• To understand the long-term effects of therapies on vascular health.

Main Methods:

• Calculation of vascular age using the SCORE project.
• Evaluation of nonpharmacological measures.
• Assessment of hypolipidemic statin therapy and hypertension pharmacotherapy, including renin-angiotensin-aldosterone system inhibitors.
• Analysis of long-term follow-up data from clinical trials.

Main Results:

• Vascular age can be positively influenced by lifestyle changes, statins, and antihypertensive drugs.
• The beneficial effects of interventions on cardiovascular outcomes persist long after treatment cessation, indicating 'vascular memory'.
• Early initiation of preventive strategies yields greater long-term benefits.

Conclusions:

• Vascular age is a dynamic and modifiable marker of cardiovascular risk.
• Pharmacological and nonpharmacological interventions can significantly improve vascular health.
• The concept of vascular memory highlights the enduring benefits of early cardiovascular risk reduction.
