Arterial stiffness.

M F O'Rourke, G Mancia

    Journal of Hypertension
    |April 1, 1999
    PubMed
    Summary
    This summary is machine-generated.

    Arterial stiffness, a key factor in cardiovascular health, varies across different arteries and pressures. Understanding its precise quantification is crucial for assessing cardiovascular load and perfusion.

    Area of Science:

    • Cardiovascular Physiology
    • Biomedical Engineering

    Background:

    • Arterial stiffness significantly influences pulse pressure, left ventricular load, and coronary perfusion.
    • Precise quantification of arterial stiffness is challenging due to variations across different arteries and pressure levels.

    Discussion:

    • Proximal elastic and peripheral muscular arteries exhibit distinct responses to aging and pharmacological agents.
    • Commonly used terms for stiffness include distensibility and compliance, with indirect indices like pulse wave velocity also employed.

    Key Insights:

    • Arterial stiffness demonstrably increases with aging and elevated blood pressure.
    • The impact of other diseases and vasoactive agents on arterial stiffness is less definitively established.

    Outlook:

    • Further research is needed to clarify the complex interplay between diseases, vasoactive agents, and arterial stiffness.
    • Developing standardized methods for precise arterial stiffness quantification is crucial for clinical applications.
