The Claim
In adults with increased cardiovascular risk, targeting a systolic blood pressure below 120 mm Hg compared to below 140 mm Hg is associated with a 13% relative reduction in all-cause mortality over a follow-up period of 3.3 to 4.7 years, based on pooled data from five randomized trials involving 39,434 patients, with observed mortality rates of 3.4% and 3.9%, respectively, though this benefit is accompanied by increased risks of hypotension, syncope, and acute kidney injury.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In adults at high risk for heart disease, lowering systolic blood pressure to below 120 mm Hg instead of below 140 mm Hg is linked to a 13% lower rate of death from any cause over about four years, but it also increases the risk of low blood pressure, fainting, and kidney injury.
See the scientific wording
In adults with increased cardiovascular risk, targeting a systolic blood pressure below 120 mm Hg compared to below 140 mm Hg is associated with a 13% relative reduction in all-cause mortality (3.4% vs. 3.9% over 3.3–4.7 years), based on pooled data from 39,434 patients across five randomized trials, though this benefit must be weighed against increased risks of hypotension, syncope, and acute kidney injury.
When blood pressure is kept lower, the heart and blood vessels face less force, which prevents damage to the kidneys, brain, and heart muscle. This reduces the chance of heart failure, stroke, and kidney failure, which are common causes of death in people with high cardiovascular risk.
What the research says
1 studyFor people at high risk of heart disease, lowering blood pressure to under 120 instead of under 140 saved lives—13% fewer died—but also caused more fainting and kidney issues. The study proves both the benefit and the risks.
