A new study in the British medical journal "The Lancet," says if the top number -- the systolic reading -- is at least 10 to 15 millimeters higher in one arm than the other, it could be a sign of vascular disease. And those circulatory problems can lead to a higher risk of heart problems, up to and including death.
