The Claim

In adults with high cardiovascular risk, targeting systolic blood pressure below 120 mm Hg provides a consistent benefit across subgroups including those with diabetes and those with prior stroke, with no statistically significant heterogeneity in effect (p>0.05 for interaction).

Source: Lowering systolic blood pressure to less than 120 mm Hg versus less than 140 mm Hg in patients with high cardiovascular risk with and without diabetes or previous stroke: an open-label, blinded-outcome, randomised trial.

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.

Cause and effect

In plain English

For adults at high risk of cardiovascular disease, lowering systolic blood pressure to below 120 mm Hg results in consistent health benefits regardless of whether they have diabetes or a prior stroke.

See the scientific wording

In adults with high cardiovascular risk, the benefit of targeting systolic blood pressure below 120 mm Hg is consistent across subgroups including those with diabetes and those with prior stroke, with no statistically significant heterogeneity in effect (p>0.05 for interaction), suggesting broad applicability within this population.

Why this might work

Lowering blood pressure reduces force on artery walls, which prevents damage to the inner lining of blood vessels and stops dangerous buildups from breaking loose, thereby preventing heart attacks and strokes.

  1. Study: Lowering systolic blood pressure to less than 120 mm Hg versus less than 140 mm Hg in patients with high cardiovascular risk with and without diabetes or previous stroke: an open-label, blinded-outcome, randomised trial.

    For people at high risk of heart problems, lowering blood pressure to under 120 helped prevent heart attacks and strokes just as much whether they had diabetes or had a stroke before, compared to those who didn’t. The study found no difference in how well the treatment worked across these groups.
