Blood pressure declines 14 to 18 years before death: It's normal for blood pressure to trend lower in the elderly--but it foreshadows the end -- ScienceDailyBlood pressure in the elderly gradually begins to decrease about 14 or so years before death, according to a new study published today in the Journal of the American Medical Association Internal Medicine. Researchers from UConn Health and the University of Exeter Medical School in the U.K. looked at the electronic medical records of 46,634 British citizens who had died at age 60 or older. The large sample size included people who were healthy as well as those who had conditions such as heart disease or dementia. They 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 without the presence of any of these diagnoses.
