At the European Society of Cardiology Congress 2026 in Munich, researchers presented seven-year results from a large community-based trial in rural China.
Adults managed to a target of below 130/80 mmHg were less likely to develop dementia and had fewer cardiovascular events than those receiving usual care, according to findings from the China Rural Hypertension Control Program.
The trial randomized 326 rural villages and followed 33,995 adults with hypertension, average age 63, over four years of active intervention plus three more years of observation. Trained non-physician community health workers supported the intensive arm with medication adjustments and lifestyle guidance.
Dementia occurred in 8.85% of the intensive-treatment group versus 10.55% in usual care, a 15% relative reduction (adjusted risk ratio 0.85). Cognitive impairment without dementia was 13% lower.

The cardiovascular event rate over the full follow-up was 2.4% per person-year in the intensive arm compared with 3.0% in usual care, as reported in Circulation.
By year seven, the intensive arm averaged 138.8/80.7 mmHg versus 152.3/86.1 in usual care. About 33.9% of the intensively treated group met the below-130/80 goal, versus 10.5% of the comparison group.
Why the 130 threshold matters
Guidance in the US is moving the same way. The 2025 American College of Cardiology and American Heart Association hypertension guideline sets a target of below 130/80 mmHg for all adults, tightening an older 140/90 standard many patients are still managed to.
According to the guideline document, each 10 mmHg drop in systolic blood pressure is linked to a 17% lower risk of coronary heart disease, a 27% lower risk of stroke, and a 20% lower risk of major cardiovascular events overall.

That matters at scale. The Centers for Disease Control and Prevention estimates that 48.1% of US adults, or roughly 119.9 million people, have high blood pressure. Only about one in four have theirs controlled.
What the intervention actually involved
The CRHCP intervention was not a solo effort. Community workers checked pressures, adjusted medicines, and coached participants on diet, salt, and activity.
Adults in the intensive arm did see more hypotension and mild low potassium than those in usual care. Serious adverse events overall were actually less common in the intensive arm than in usual care (47.15% vs 49.78%).
"Hypertension is known to be a modifiable risk factor for dementia but there is still limited long-term evidence," said Professor Yingxian Sun of The First Affiliated Hospital of China Medical University in Shenyang, the trial's principal investigator.

If your reading sits between 130 and 139 systolic, talk with your clinician about whether a stricter target fits your risk profile, and what pathway, lifestyle first or medication, makes sense. Do not adjust your prescriptions on your own.
