Your feet might not be the first place you think of when you hear “heart health”, but they can tell you a lot about your cardiovascular system. Symptoms in your feet like pain, numbness, or swelling, could be indicative of serious heart problems or clogged arteries. Peripheral artery disease (PAD) and coronary artery disease (CAD) are two serious types of atherosclerosis that might manifest in your feet and signal restricted blood flow from plaque in your arteries.
Understanding Peripheral Artery Disease (PAD)
PAD occurs when plaque buildup leads to clogged arteries, causing significant discomfort and limited mobility in the legs and feet. According to the Cleveland Clinic, PAD can cause pain, cramping, and in severe cases, limb loss. Symptoms like difficulty standing for long periods or frequent leg cramps should prompt medical screening for PAD.
Testing for Clogged Arteries
Early detection of PAD is crucial to prevent serious complications. Physicians may measure your pulse in your feet or perform an ankle-brachial index (ABI) test, using ultrasound to compare blood pressure in your ankle and arm. A family history of heart disease or PAD, or symptoms like swelling in your feet or ankles, should prompt immediate medical attention.
The Impact of Poor Circulation
Poor circulation affects your feet significantly. Reduced blood flow deprives tissues of oxygen and nutrients, causing pain, numbness, tingling, and slower wound healing. Plaque buildup further restricts blood supply, contributing to PAD. Diabetics need to monitor blood sugar levels, as high levels can exacerbate foot pain and numbness.
