Hypertension and mortality

G I Svensson, A Lundström

    Journal of Chronic Diseases
    |January 1, 1982
    PubMed
    Summary

    A new model ranks the combined mortality risk of systolic and diastolic blood pressure by age. This hypertension model introduces a biological effective blood pressure (Pe) calculation for risk assessment.

    Area of Science:

    • Cardiovascular medicine
    • Public health
    • Biostatistics

    Background:

    • Hypertension is a major global health concern.
    • Current models for blood pressure risk assessment have limitations.
    • Age-related mortality effects of blood pressure require refined analysis.

    Purpose of the Study:

    • To introduce a novel model for ranking the combined mortality-effect of systolic and diastolic blood pressure.
    • To enable continuous comparison of blood pressure values and risk percentile distribution.
    • To propose new strategies for addressing hypertension.

    Main Methods:

    • Developed a ranking model integrating systolic (Ps) and diastolic (Pd) blood pressure.
    • Introduced a formula to calculate biological effective blood pressure (Pe): Pe = 0.45Ps + 0.55Pd.
    • Incorporated population distribution by blood pressure and age for risk assessment.

    Main Results:

    • The model provides a continuous risk ranking for combined blood pressure.
    • It allows for percentile distribution of mortality risk based on population data.
    • The biological effective blood pressure (Pe) offers a unified measure.

    Conclusions:

    • The new model offers a refined approach to assessing combined blood pressure mortality risk.
    • It facilitates better understanding of hypertension's impact across different age groups.
    • The biological effective blood pressure concept may guide future hypertension management strategies.
