The Claim
In adults with increased cardiovascular risk, targeting systolic blood pressure below 120 mm Hg compared to below 140 mm Hg is associated with a 234% increased risk of syncope, a 166% increased risk of acute kidney injury, and a 26% increased risk of electrolyte abnormalities, based on pooled data from 39,434 patients across five trials.
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 with high cardiovascular risk, lowering systolic blood pressure to below 120 mm Hg instead of below 140 mm Hg is associated with higher rates of syncope, acute kidney injury, and electrolyte abnormalities.
See the scientific wording
In adults with increased cardiovascular risk, targeting systolic blood pressure below 120 mm Hg compared to below 140 mm Hg is associated with a 234% increased risk of syncope (0.8% vs. 0.5%), a 166% increased risk of acute kidney injury (1.1% vs. 0.6%), and a 26% increased risk of electrolyte abnormalities (6.3% vs. 5.0%), based on pooled data from 39,434 patients across five trials.
When blood pressure drops too low, the body's pressure sensors detect it and slow the heart and widen blood vessels, causing fainting. At the same time, the kidneys receive less blood, which stops them from filtering properly and causes salt and fluid imbalances.
What the research says
1 studyFor people at high risk of heart disease, pushing blood pressure lower than 120 can cause more fainting, kidney problems, and salt imbalances — and this study proves it. But it also shows they’re less likely to die or have a heart attack.
