Hi. I wasn't sure whether to post this on the "forum" or the "news" section, but since potential donors often ask about blood pressure testing, and past donors should be keeping a close watch on our blood presure, I'll post it here. This was new information for me, so perhaps others have not heard of it either.
Paris (AFP-Jiji)--- Measuring blood pressure on both arms rather than only one can reveal an elevated risk of heart disease or even death, according to a recent study.
In a review of medical literature, researchers at the University of Exeter found a difference in the so-called systolic blood pressure between arms can be a useful indicator of the likelihood of heart trouble.
People with high blood pressure-- also called hypertension-- have an increased risk of developing heart disease, stroke, kidney disease and dementia, previous research has shown.
High blood pressure is defined by the World Health Organization as 140 over 90 millimeters of mercury or more. Mercury is used in blood pressure gauges.
The first number measures maximum heart pressure (systolic), while the second measures pressure when the heart is in a resting phase (diastolic).
Published in the British medical journal The Lancet, the findings suggest that both-arm blood pressure checks should become standard practice, the researchers said.
The probe reviewed 28 studies with data on the difference in systolic blood pressure between arms.
They concluded that a gap of 15 millimeters of mercury or more was linked with an increasing risk of the narrowing and hardening of the arteries that supply blood to the legs and feet.
It was also associated with pre-existing cerebrovascular disease, which effects blood supply to the brain and can contribute to dementia.
Above this threshold, deaths rates to cardiovascular problems likewise went up.
Most such cases are "clinically silent" and double-arm checks would better identify those at risk, the study said.
