    In most cases, blood pressure will taken in the leg if the person is at increased risk for atherosclerosis (thus often measured in diabetic patients). Atherosclerosis is a disease process causing plaque build-up with the arterial walls. Differences in blood pressure between the arms and legs is one tool used in the medical and research setting to determine risk for peripheral arterial disease (PAD or atherosclerosis in the legs). Typically both pressures should be around the same or the leg pressures will be slightly elevated. However, if there is plaque build-up, the pressure in the legs will lower due to less blood flow through the vasculature. Typically this is measured through ABI- the pressure at the ankle / the pressure of the brachial artery. The ABI ratio should be between 0.90- 1.50. If the ratio is lower than .90, the individual may have plaque build-up causing a narrowing of the artery. This generally is not a problem in assymptomic patients. However the plaque can rupture and cause blood clots.
