In a community-based trial in rural China, an intensive blood-pressure decreasing intervention diminished the incidence of dementia in contrast with typical care, in line with outcomes from the China Rural Hypertension Management Program offered in a Scorching Line session at the moment at ESC Congress 2026.
It’s estimated that the variety of individuals with dementia will improve globally from 57 million circumstances in 2019 to 153 million circumstances in 2050. Within the absence of healing therapy, main prevention of dementia is changing into a public well being precedence.
“Hypertension is thought to be a modifiable threat issue for dementia however there’s nonetheless restricted long-term proof that blood-pressure decreasing can stop dementia on the inhabitants stage, “Professor Yingxian Solar from The First Affiliated Hospital of China Medical College, Shenyang, China, the Principal Investigator of the China Rural Hypertension Management Program (CRHCP).
CRHCP is a cluster-randomized trial assessing the efficacy of an intensive blood stress intervention led by non-physician group healthcare suppliers. It has already been demonstrated that the intensive blood stress intervention is efficient at decreasing heart problems and demise. “One other vital goal of the CRHCP was to evaluate whether or not intensive blood-pressure decreasing can cut back the incidence of all-cause dementia,” famous investigator and presenter, Physician Shanshan Zhong, additionally from The First Affiliated Hospital of China Medical College.
Within the CRHCP, 326 rural Chinese language villages have been randomized (1:1) to a non-physician group healthcare provider-led intervention or typical care. Eligible individuals have been adults aged 40 years or extra with an untreated systolic blood stress (SBP) of not less than 140 mmHg or a diastolic blood stress (DBP) of not less than 90 mmHg (not less than 130 mmHg and 80 mmHg for these at excessive threat of heart problems or if at present taking antihypertensive treatment). Within the intervention group, educated non-physician group healthcare suppliers initiated and titrated antihypertensive drugs in line with a easy stepped-care protocol to realize a blood stress objective of SBP lower than 130 mmHg and DBP lower than 80 mmHg with supervision from primary-care physicians. The energetic trial part lasted for 4 years, adopted by three extra years of statement solely. In complete, 33,995 individuals have been enrolled who had a imply age of 63.0 years; 61% have been ladies.
The intervention group had better reductions in blood stress from baseline vs. the same old care group on the finish of the seven-year research interval (SBP reductions of 17.6 mmHg vs. 2.4 mmHg).
Of observe, the intervention group had a 15% decrease threat of dementia than the usual-care group at seven years (8.85% vs. 10.55%; adjusted threat ratio 0.85; 95% confidence interval 0.78 to 0.91; p<0.001). The intervention group additionally had a 13% decrease threat of cognitive impairment and no dementia (p<0.001).
The proportion of sufferers with severe opposed occasions was additionally much less with the intervention than typical care (47.15% vs. 49.78%).
“On this massive community-based trial, a scalable intervention delivered by non-physician healthcare suppliers not solely resulted in substantial reductions in blood stress but in addition diminished the chance of dementia,” summarized Professor Solar, who concluded, “These outcomes help the long-term sustainability of integrating structured blood stress administration into routine main look after dementia prevention on the inhabitants stage.” European Society of Cardiology
