For adults at higher risk of heart disease, lowering systolic blood pressure to below 120 mm Hg reduces deaths and serious heart events consistently, regardless of age, sex, diabetes status, or prior heart disease.
See the scientific wording
In adults with increased cardiovascular risk, targeting systolic blood pressure below 120 mm Hg compared to higher targets results in consistent reductions in all-cause mortality and major cardiovascular events across subgroups defined by age, sex, diabetes status, and prior cardiovascular disease.

Systematic Review With Meta-AnalysisMeta-analysis2025
For people at high risk of heart problems, lowering blood pressure to under 120 helped reduce deaths and heart events—and this benefit was seen in men, women, older and younger people, and those with or without diabetes or prior heart disease.

That doesn't mean it's settled — it just means no study has tested the opposite.
Quality-weighted scoring: we follow the GRADE framework — each study is rated High, Moderate, Low, or Very Low based on study design, methodology rigor, and risk of bias. A single high-quality RCT can outweigh several weaker observational studies.
Scores reflect study quality, not just count.
Lowering blood pressure reduces the force pushing against artery walls, which prevents damage to the inner lining of blood vessels. This stops the buildup of fatty plaques and makes existing plaques less likely to break open, which prevents heart attacks and strokes.

Mechanism
1 studyLowering blood pressure below 120 mm Hg reduces the force on artery walls, which stops damage that leads to clogged arteries. This prevents heart attacks and strokes, and it works the same way in everyone regardless of age, sex, diabetes, or past heart problems.
Lowering blood pressure reduces the force pushing against artery walls, which prevents damage to the inner lining of blood vessels. This stops the buildup of fatty plaques and makes existing plaques less likely to break open, which prevents heart attacks and strokes.
Systolic blood pressure below 120 mm Hg reduces mechanical stress on arterial walls stress points, decreasing endothelial cell activation and permeability
Reduced endothelial activation lowers oxidative stress and inflammatory cytokine production, slowing monocyte recruitment and foam cell formation in the arterial intima
Decreased plaque inflammation and stabilization of the fibrous cap reduce the likelihood of rupture and subsequent thrombus formation
Fewer thrombotic occlusions in coronary and cerebral arteries prevent myocardial infarction and ischemic stroke
Prevention of acute cardiovascular events and chronic organ damage reduces all-cause mortality
