Randomized Controlled TrialHuman
In high-risk people without diabetes, aiming for a top blood pressure number under 120 instead of under 140 cut the chance of major heart and blood vessel problems by about 25%, which matches the claim.
A Randomized Trial of Intensive versus Standard Blood-Pressure Control
Randomized Controlled TrialHuman2015
In a large trial of high-risk adults without diabetes, aiming for a blood pressure below 120 instead of below 140 cut the risk of major heart problems by about 25%, matching the claim.
Cohort StudyHuman2026
The study found that tight blood pressure control cut major heart and blood vessel events by about 14–17%, not 25%, but it agrees that the strategy helps. The 25% number is higher than the study's main estimate.

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.
When blood pressure is lowered more forcefully with extra medicines, the push of blood against artery walls becomes weaker. This reduces wear and tear on the arteries. Fatty deposits inside arteries break open less often and cause fewer clots. The heart also has less resistance to pump against, so it needs less oxygen and suffers less damage. As a result, fewer heart attacks, strokes, heart failures, and heart-related deaths occur.

In high-risk adults without diabetes, aiming for systolic blood pressure under 120 cut the relative risk of major heart and blood vessel events by 25% versus aiming for under 140.
Mechanism
2 studiesThe unified picture is that pushing blood pressure down harder with more medicines reduces the physical force on artery walls and on the heart. That lower force means less damage to arteries and less strain on the heart, which directly prevents heart attacks, strokes, heart failure, and heart-related death. The evidence for this exact chain comes from large trials that measured the final outcomes, while the intermediate biological steps are inferred from how blood pressure works.
When blood pressure is lowered more forcefully with extra medicines, the push of blood against artery walls becomes weaker. This reduces wear and tear on the arteries. Fatty deposits inside arteries break open less often and cause fewer clots. The heart also has less resistance to pump against, so it needs less oxygen and suffers less damage. As a result, fewer heart attacks, strokes, heart failures, and heart-related deaths occur.
Intensive antihypertensive therapy, including higher use of diuretics, ACE inhibitors, angiotensin-receptor blockers, beta-blockers, and calcium-channel blockers, achieves a mean systolic blood pressure of approximately 120 mm Hg compared with approximately 140 mm Hg in standard treatment.
The lower systolic blood pressure reduces mechanical tensile and shear stress on arterial walls and decreases left ventricular afterload, lowering cardiac work and myocardial oxygen demand.
Reduced arterial wall stress stabilizes atherosclerotic plaques, decreasing plaque rupture and thrombosis, while lower afterload reduces myocardial ischemia and heart failure progression.
These vascular and cardiac effects translate into fewer myocardial infarctions, acute coronary syndromes, strokes, heart failures, and cardiovascular deaths.

The study found that tight blood pressure control cut major heart and blood vessel events by about 14–17%, not 25%, but it agrees that the strategy helps. The 25% number is higher than the study's main estimate.
A study found that people who got their blood pressure under 120 had about 42% fewer heart events than those with higher blood pressure, so the idea that lower is better is supported. But the study included people with diabetes, while the claim is about people without diabetes, so it is not a perfect match.
Impact of intensive versus standard blood pressure control on cardiovascular events in hypertensive patients: a meta-analysis of randomized controlled trials.
The study found that aiming for blood pressure below 120 instead of 140 lowered the risk of strokes, heart attacks, and heart-related deaths by roughly 17–27%. So the claim that it cuts heart problems by about a quarter is in the right ballpark.
