Arterial compliance in essential hypertension.

F H Messerli, E D Frohlich, H O Ventura

    Journal of Cardiovascular Pharmacology
    |January 1, 1985
    PubMed
    Summary

    Arterial compliance, a measure of blood vessel elasticity, declines early in hypertension, especially in older adults. Age is the primary risk factor for impaired arterial function and systemic arterial disease.

    Area of Science:

    • Cardiovascular Medicine
    • Hypertension Research
    • Geriatric Cardiology

    Background:

    • Essential hypertension is a prevalent cardiovascular condition.
    • Aging is associated with physiological changes in arterial properties.
    • Early detection of arterial dysfunction is crucial for cardiovascular disease management.

    Purpose of the Study:

    • To evaluate arterial compliance in patients with essential hypertension.
    • To identify the relationship between arterial compliance and hypertension severity.
    • To determine the influence of age and blood pressure on arterial compliance.

    Main Methods:

    • Assessed arterial compliance using three indices: pulse wave velocity, pulse pressure stroke volume, and diastolic pressure decay analysis.
    • Compared arterial compliance in patients with established hypertension, borderline hypertension, and controls.
    • Analyzed age, systolic, and diastolic pressures as determinants of arterial compliance.

    Main Results:

    • Arterial compliance was significantly impaired in patients with established essential hypertension, particularly in elderly individuals.
    • Two of the three assessed indices indicated reduced arterial compliance even in borderline hypertension.
    • Age, systolic blood pressure, and diastolic blood pressure were independent predictors of pulse wave velocity.

    Conclusions:

    • Arterial compliance deteriorates early in the course of hypertensive cardiovascular disease, even at borderline blood pressure levels.
    • Aging is identified as the most significant risk factor for systemic arterial disease.
    • These findings highlight the importance of assessing arterial compliance in hypertensive patients, especially the elderly.
