Insights
Arterial stiffness, a key indicator of vascular aging and hypertension, predicts cardiovascular events. Understanding arterial and ventricular stiffness is crucial for assessing cardiovascular performance.
Area of Science:
- Cardiovascular Physiology
- Gerontology
- Hypertension Research
Background:
- Arterial stiffness is a hallmark of aging and hypertension, contributing to cardiovascular events.
- It reflects early atherosclerotic changes and is linked to increased systolic blood pressure.
- Vascular and cardiac stiffness interact, impacting overall cardiovascular performance.
Purpose of the Study:
- To review methods for assessing arterial and ventricular stiffness.
- To examine alterations in stiffness during aging and hypertension.
- To explain ventricular-arterial coupling and its role in cardiovascular health.
Main Methods:
- Review of established and emerging techniques for measuring arterial stiffness.
- Analysis of indices used to quantify ventricular stiffness.
- Discussion of physiological aging and hypertension models.
Main Results:
- Numerous methods exist to evaluate vascular stiffness with prognostic value.
- Arterial and ventricular stiffness are interconnected, influencing cardiovascular function.
- Both aging and hypertension significantly alter arterial and ventricular stiffness.
Conclusions:
- Arterial stiffness assessment is vital for early disease detection and risk stratification.
- Understanding the interplay between arterial and ventricular stiffness is key to managing cardiovascular health in aging and hypertensive populations.
- Ventricular-arterial coupling provides critical insights into cardiovascular performance limitations.
Abstract:
The assessment of arterial stiffness, a common feature of aging, exacerbated by pathological conditions like hypertension, has become an attractive tool for identifying structural and functional changes of the arteries even in an early stage of the atherosclerotic disease. Arterial stiffness has been recognized as an important physio-pathological determinant for the age-related rise in systolic blood pressure, demonstrating also an independent predictive value for cardiovascular events. In the recent decades, many techniques and indices to evaluate vascular stiffness have been developed and extensive data concerning their prognostic value have been collected. Moreover, it has become clear that vessel and heart must be considered as a unique system, in which combined stiffness of vessel and heart interacts to limit cardiovascular performance. In this review, main methods and indices used to estimate arterial and ventricular stiffness are presented, focusing on their alteration in physiological aging and arterial hypertension. Furthermore, the concept of ventricular-arterial coupling is explained in order to give an insight to the interplay between arterial and ventricular stiffness in aging and hypertension.
