In a community-based trial in rural China, an intensive blood-pressure reducing intervention diminished the incidence of dementia in contrast with normal care, in response to outcomes from the China Rural Hypertension Management Program introduced in a Sizzling Line session as we speak at ESC Congress 2026.
It’s estimated that the variety of individuals with dementia will enhance globally from 57 million circumstances in 2019 to 153 million circumstances in 2050. Within the absence of healing remedy, main prevention of dementia is turning into a public well being precedence.
“Hypertension is understood to be a modifiable danger issue for dementia however there may be nonetheless restricted long-term proof that blood-pressure reducing can stop dementia on the inhabitants stage,” stated 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 strain intervention led by non-physician group healthcare suppliers. It has already been demonstrated that the intensive blood strain intervention is efficient at decreasing heart problems and demise.3 “One other essential goal of the CRHCP was to evaluate whether or not intensive blood-pressure reducing can scale 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 randomised (1:1) to a non-physician group healthcare provider-led intervention or normal care. Eligible members have been adults aged 40 years or extra with an untreated systolic blood strain (SBP) of not less than 140 mmHg or a diastolic blood strain (DBP) of not less than 90 mmHg (not less than 130 mmHg and 80 mmHg for these at excessive danger of heart problems or if presently taking antihypertensive medicine). Within the intervention group, skilled non-physician group healthcare suppliers initiated and titrated antihypertensive medicines in response to a easy stepped-care protocol to realize a blood strain aim 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 further years of commentary solely. In complete, 33,995 members have been enrolled who had a imply age of 63.0 years; 61% have been girls.
The intervention group had larger reductions in blood strain from baseline vs. the standard care group on the finish of the seven-year research interval (SBP reductions of 17.6 mmHg vs. 2.4 mmHg).
Of be aware, the intervention group had a 15% decrease danger of dementia than the usual-care group at seven years (8.85% vs. 10.55%; adjusted danger ratio 0.85; 95% confidence interval 0.78 to 0.91; p<0.001). The intervention group additionally had a 13% decrease danger 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 normal 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 strain but additionally diminished the chance of dementia,” summarised Professor Solar, who concluded, “These outcomes assist the long-term sustainability of integrating structured blood strain administration into routine main take care of dementia prevention on the inhabitants stage.”
