Circulating atrial natriuretic polypeptide in essential hypertension.

M Kohno, K Yasunari, T Matsuura

    American Heart Journal
    |May 1, 1987
    PubMed
    Summary

    Plasma atrial natriuretic polypeptide (ANP) levels are elevated in essential hypertension, particularly with high blood pressure or left ventricular hypertrophy. Effective antihypertensive therapy significantly reduces these elevated ANP levels.

    Area of Science:

    • Cardiology
    • Endocrinology
    • Nephrology

    Background:

    • Essential hypertension is a complex cardiovascular condition.
    • Atrial natriuretic polypeptide (ANP) plays a role in cardiovascular regulation.
    • Understanding ANP's role in hypertension is crucial for management.

    Purpose of the Study:

    • To investigate the significance of plasma ANP in essential hypertension.
    • To compare ANP levels across hypertensive, borderline hypertensive, and normotensive groups.
    • To explore the relationship between ANP, blood pressure, and left ventricular hypertrophy (LVH).

    Main Methods:

    • Plasma ANP concentrations were measured in 43 essential hypertensive, 16 borderline hypertensive, and 17 normotensive subjects.
    • Correlation analysis was performed between mean blood pressure and plasma ANP levels.

  • ANP levels were re-assessed after 4 weeks of antihypertensive therapy.

    • Main Results:

    • Plasma ANP levels were significantly higher in hypertensive subjects compared to borderline and normotensive controls.
    • Hypertensive subjects with LVH exhibited higher plasma ANP levels than the overall hypertensive group.
    • A significant positive correlation was found between mean blood pressure and plasma ANP levels in hypertensive subjects.
    • Effective antihypertensive therapy led to a significant decrease in plasma ANP levels.

    Conclusions:

    • Plasma ANP is frequently elevated in hypertensive individuals, especially those with high blood pressure or LVH.
    • Elevated ANP levels in hypertension can be reduced by effective antihypertensive drug therapy.
    • ANP may serve as a biomarker and therapeutic target in managing essential hypertension.
