Hypertension and mortality

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.
