Vascular Aging and Arterial Stiffness

Area of Science:

• Cardiology
• Vascular Medicine
• Gerontology

Background:

• Cardiovascular diseases (CVD) cause a third of global deaths, with systemic arterial hypertension (SAH) responsible for over half.
• Type 2 diabetes mellitus independently elevates SAH risk by damaging arterial walls and increasing stiffness.
• Vascular aging is associated with oxidative stress, free radicals, and neuroendocrine/genetic factors.

Purpose of the Study:

• To review literature on vascular aging in relation to cardiovascular risk factors.
• To explore tools for early identification of vascular damage.
• To highlight the significance of pulse wave velocity (PWV) in assessing arterial stiffness.

Main Methods:

• Literature review focusing on vascular aging, CVD risk factors, and arterial stiffness assessment.
• Analysis of studies utilizing pulse wave velocity (PWV) as a biomarker.
• Examination of the relationship between Type 2 diabetes and arterial wall changes.

Main Results:

• Arterial stiffness, a marker of vascular aging, is significantly influenced by conditions like Type 2 diabetes.
• Pulse wave velocity (PWV) is a reliable, non-invasive method for quantifying arterial stiffness.
• PWV reflects the timing of wave reflection, differing between younger (diastolic) and older (systolic) individuals.

Conclusions:

• Vascular aging and arterial stiffness are critical components of cardiovascular risk assessment.
• PWV is a valuable tool for early detection of vascular damage and cardiovascular events.
• Understanding the mechanisms of vascular aging is crucial for managing SAH and Type 2 diabetes comorbidities.
