Plasma urea in hypertensive patients

C J Bulpitt, A Breckenridge

    British Heart Journal
    |July 1, 1976
    PubMed
    Summary

    Plasma urea significantly increases over time in hypertensive patients, influenced by initial urea levels but not sex or hypertension type. This finding aids clinical assessment of hypertension progression.

    Area of Science:

    • Nephrology
    • Cardiology
    • Clinical Biochemistry

    Background:

    • Hypertension is a major risk factor for cardiovascular and renal diseases.
    • Plasma urea levels can be an indicator of kidney function and overall health.
    • Understanding factors influencing plasma urea in hypertensive patients is crucial for disease management.

    Purpose of the Study:

    • To investigate the annual changes in plasma urea in hypertensive patients.
    • To determine the relationship between plasma urea, age, blood pressure, and sex in hypertension.

    Main Methods:

    • Analysis of plasma urea levels in 253 hypertensive patients over time.
    • Examination of plasma urea in relation to age and blood pressure in 1217 hypertensive patients.
    • Statistical analysis to identify significant correlations and dependencies.

    Main Results:

    • Plasma urea showed a significant annual increase, independent of sex or hypertension type, but dependent on initial levels.
    • Plasma urea correlated significantly with age and both systolic and diastolic blood pressure.
    • Plasma urea was higher in men than women under 60, with a greater increase related to mean blood pressure in men.
    • A quadratic relationship between age and plasma urea was observed in both sexes, with increases noted between ages 60 and 80.

    Conclusions:

    • Annual plasma urea increments in hypertensive patients are predictable based on initial levels.
    • Age and blood pressure are significant determinants of plasma urea levels in hypertension.
    • Sex influences plasma urea levels in relation to age and blood pressure in hypertensive individuals.
