What is the Origin of Vascular Stiffness?

The term is a descriptive physiological and clinical one, with 'vascular' referring to blood vessels and 'stiffness' indicating reduced compliance or flexibility. It is quantified clinically by measuring the Pulse Wave Velocity (PWV), the speed at which the pulse travels along the arterial tree. Its importance has grown as clinicians recognize it as an early, measurable sign of chronic cardiovascular risk.

What is the Mechanism of Vascular Stiffness?

The mechanism involves fundamental structural and cellular changes within the arterial wall's extracellular matrix, primarily characterized by the degradation of elastin fibers and the excessive, abnormal accumulation of stiff collagen fibers. This process is accelerated by chronic inflammation, oxidative stress, and hormonal shifts, such as the decline in protective estrogen levels post-menopause or the pro-fibrotic effects of hormones like Angiotensin II. The resulting mechanical changes impair endothelial function and increase peripheral vascular resistance.

Vascular Stiffness

Meaning

Vascular Stiffness, also known as arterial stiffness, is a pathological condition characterized by the loss of elasticity and increased rigidity of the arterial walls, particularly in the large, central elastic arteries like the aorta. This stiffening is considered a hallmark of vascular aging and is an independent, powerful predictor of cardiovascular disease risk, including hypertension, heart failure, and stroke. It compromises the circulatory system’s ability to buffer the pulse wave generated by the heart.
