What is the Origin of Arterial Resilience?

This concept is derived from the field of cardiovascular physiology and clinical cardiology, focusing on arterial stiffness indices like pulse wave velocity as quantifiable measures of biological age. The understanding that vascular health is significantly modulated by endocrine factors, such as estrogen, testosterone, and cortisol, solidifies its relevance in hormonal health. It moves beyond simple blood pressure measurement to assess the intrinsic health of the circulatory system.

What is the Mechanism of Arterial Resilience?

Hormonal balance plays a pivotal role in maintaining this resilience, particularly through the action of sex steroids on the endothelial lining and smooth muscle cells. Estrogen, for example, promotes nitric oxide bioavailability, which is essential for vasodilation and maintaining endothelial function. Conversely, chronic elevation of cortisol and insulin resistance can accelerate the deposition of advanced glycation end products, leading to arterial stiffening and diminished elasticity.

Arterial Resilience

Meaning

The capacity of the arterial vasculature to maintain optimal structural integrity, elasticity, and functional responsiveness to hemodynamic forces and neuro-hormonal signals throughout the lifespan. It is a critical metric of cardiovascular health, reflecting the arterial wall’s resistance to stiffening, calcification, and endothelial dysfunction. High arterial resilience indicates a reduced clinical risk profile for major cardiovascular events.
