The large sample size included people who were healthy as well as those who had conditions such as heart disease or dementia.
“Our large scale study has shown for the first time that blood pressure drops for around 14 years before death, in older patients.”

Researchers from the University of Exeter Medical School and UConn Health in the United States found blood pressure declines were steepest in patients with dementia, heart failure, late-in-life weight loss, and those who had high blood pressure to begin with. But long-term declines also occurred in healthier people.
Professor David Melzer, from the University of Exeter Medical School, said: “Our large scale study has shown for the first time that blood pressure drops for around 14 years before death, in older patients. We now need more research to understand why this happens. It is important for physicians to understand as much as possible around ageing and blood pressure, to help personalise treatment.”
