Peripheral Arterial Disease (PAD) is a common circulation problem. PAD, or peripheral arterial disease, is the narrowing of blood vessels outside of the heart and brain. It’s often caused by the accumulation of fatty deposits in the arteries (atherosclerosis). When these arteries become clogged, blood flow to the arms, legs, and certain organs is restricted. This can result in limited mobility, increased risk of heart attack or stroke, limb amputations, and, in some cases, death. An estimated 27 million people in Europe and North America have PAD; 60% of those individuals have no symptoms. Individuals with PAD are at an increased risk of heart attack and stroke. A simple test, the Ankle-brachial index, is used to diagnose PAD by comparing the blood pressure in the ankle and arm to see how well blood is flowing.
