MedPage Today reports, “A substantial difference in blood pressure from one arm to the other could be a warning sign for overall cardiovascular and mortality risk,” according to a meta-analysis published online in The Lancet.
Investigators found that “a systolic pressure difference of 15 mm Hg or more between the right and left arm was linked to a 70% elevated risk of death from cardiovascular causes (P=0.01).”
The researchers reported that “that pressure differential also pointed to a 60% higher likelihood of dying from any cause (P=0.02).”
HealthDay reports, “It makes no difference which arm has the higher or lower pressure, it’s the difference between them that matters, the study authors said.”
So, the bottom line? The next time you have your blood pressure checked, be sure it’s done in both arms.
