Reflex cardiovascular regulation in humans.

G Mancia, G Grassi, A Ferrari

    Journal of Cardiovascular Pharmacology
    |January 1, 1985
    PubMed
    Summary

    The carotid baroreceptor reflex is more effective at lowering blood pressure than raising it. Its function in aging, exercise, and hypertension is not impaired for blood pressure control.

    Area of Science:

    • Cardiovascular physiology
    • Neuroscience
    • Homeostasis

    Background:

    • Arterial baroreceptors are crucial for cardiovascular control.
    • Studies in humans are limited by technical and ethical constraints.
    • The variable-pressure neck-chamber technique offers valuable insights.

    Purpose of the Study:

    • To evaluate the carotid baroreceptor reflex using the neck-chamber technique.
    • To examine baroreceptor control in various physiological and pathophysiological states.
    • To compare arterial and cardiopulmonary receptor roles in cardiovascular regulation.

    Main Methods:

    • Utilized the variable-pressure neck-chamber technique in human subjects.
    • Assessed carotid baroreceptor reflex function.
    • Reviewed existing literature on baroreceptor effects.

    Main Results:

    • The carotid baroreceptor reflex set-point is eccentrically located, favoring counteraction of blood pressure falls.
    • Arterial baroreflex impairment is not tenable for arterial pressure control in aging, exercise, and hypertension.
    • Cardiopulmonary receptors, not arterial baroreceptors, predominate in modulating plasma renin activity.

    Conclusions:

    • The carotid baroreceptor reflex is a key homeostatic mechanism for blood pressure regulation.
    • Age, exercise, and hypertension do not impair arterial baroreceptor control of blood pressure.
    • Cardiopulmonary receptors play a dominant role in blood volume homeostasis via renin modulation.
