Significant reductions seen in total CVD, all-cause mortality for those aged 60 years and older; significant reductions also seen for those younger than 60 years

THURSDAY, June 20, 2024 (HealthDay News) — For older and younger adults with hypertension, a nonphysician-implemented, multifaceted, intensive blood pressure intervention can reduce the risk for cardiovascular disease (CVD) and all-cause mortality, according to a study published online June 18 in JAMA Cardiology.
Xiaofan Guo, M.D., Ph.D., from the First Hospital of China Medical University in Shenyang, and colleagues conducted a 48-month follow-up study of the China Rural Hypertension Control Project from 2018 to 2023. Participants recruited from 326 villages in rural China, aged 60 years and older and younger than 60 years, with a diagnosis of hypertension were included (22,386 and 11,609 individuals, respectively).
Among the older adults with hypertension, 11,289 and 11,097 were randomly assigned to a nonphysician, community health care practitioner-implemented multifaceted intervention to achieve blood pressure of less than 130/80 mm Hg and to a usual-care group, respectively. The researchers found a significantly lower rate of total CVD and all-cause mortality in the intervention group versus usual-care group (hazard ratios, 0.75 and 0.90, respectively). The risk reductions were also significant for total CVD, stroke, heart failure, and cardiovascular death among adults younger than 60 years (hazard ratios, 0.64, 0.64, 0.39, and 0.54, respectively). No significant between-group differences were seen in the incidences of injurious falls, symptomatic hypotension, syncope, and results for kidney outcomes in either age group.
“These results have substantial implications for the future of hypertension management among older adults who represent a large proportion of the population and high absolute risk for CVD complications,” the authors write.
