Blood 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.
“Our work highlights the importance of conducting research evaluating older patients like those seen in physician practices everywhere,” said George Kuchel, one of the study authors and director of the University of Connecticut Center on Aging at UConn Health.
However, Kuchel emphasized, “I would be very concerned if anyone were to interpret our article as suggesting that hypertension should not be treated in late life or that they should stop their blood pressure medications.”
The findings should make both doctors and researchers carefully consider what dropping blood pressure really means for older patients, he added.
