The Claim

In adults with high cardiovascular risk, targeting a systolic blood pressure of less than 120 mm Hg reduces the incidence of major cardiovascular events—including myocardial infarction, stroke, heart failure hospitalization, revascularization, or cardiovascular death—by 12% compared to targeting less than 140 mm Hg over a median follow-up of 3.4 years, with a hazard ratio of 0.88 (95% CI 0.78–0.99; p=0.028).

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.

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

In adults at high risk for heart disease, lowering systolic blood pressure to under 120 mm Hg instead of under 140 mm Hg results in a 12% lower rate of heart attacks, strokes, heart failure hospitalizations, revascularization procedures, or cardiovascular death over approximately 3.4 years.

See the scientific wording

In adults with high cardiovascular risk, targeting a systolic blood pressure of less than 120 mm Hg reduces the incidence of major cardiovascular events—including myocardial infarction, stroke, heart failure hospitalization, revascularization, or cardiovascular death—by 12% compared to targeting less than 140 mm Hg over a median follow-up of 3.4 years, with a hazard ratio of 0.88 (95% CI 0.78–0.99; p=0.028), indicating a clinically meaningful benefit in this population.

Why this might work

Lowering blood pressure reduces the force pushing against artery walls, which prevents damage to the inner lining of arteries, stops fatty deposits from breaking loose, and keeps blood clots from forming, thereby preventing heart attacks, strokes, and other serious heart events.

    For people at high risk of heart problems, lowering blood pressure to under 120 instead of under 140 reduced their chance of having a heart attack, stroke, or other serious heart event by about 12%, according to a big study. It worked, but some people fainted more often.
