Optimal blood pressure is 115/75 mmHg, associated with minimal vascular risk. Achieving blood pressure control remains a challenge, emphasizing the need for primary prevention and lifestyle changes.

Area of Science:

Cardiology
Public Health
Hypertension Research

Background:

Blood pressure is continuously linked to cardiovascular risk.
Defining hypertension relies on arbitrary thresholds where treatment benefits outweigh risks.

Purpose of the Study:

To review and define optimal blood pressure levels.
To examine current blood pressure thresholds and their implications for cardiovascular risk.

Main Methods:

Review of recent reports and meta-analyses on blood pressure thresholds.
Analysis of studies investigating blood pressure levels and associated morbidity/mortality.

Main Results:

A blood pressure of 115/75 mmHg is associated with minimal vascular mortality, suggesting it as optimal.

Related Experiment Videos

Lower blood pressure levels correlate with reduced morbidity and mortality, even below traditional hypertension ranges.

Current hypertension treatment goals (140/90 mmHg) are often not met, and specific high-risk groups may benefit from lower targets.

Conclusions:

A population-level optimal blood pressure is 115/75 mmHg, minimizing vascular risk.
Effective blood pressure control is a significant challenge, with over half of hypertensive patients uncontrolled.
Strengthening primary hypertension prevention and promoting optimal blood pressure through lifestyle interventions are crucial.
