Peripheral artery disease occurs when the arteries in the legs or arms become narrowed, reducing blood flow and leading to fatigue and discomfort during walking or daily activities. Common symptoms include cramps, numbness, and cold feet, often developing gradually over time. PAD also increases the risk of serious complications such as heart attack, stroke, and slow-healing wounds.

With more people being diagnosed, ongoing clinical trials are focused on advancing treatments, including new medications, minimally invasive procedures, and personalized exercise programs. These approaches aim to improve circulation, support mobility, and help reduce future health risks for individuals living with PAD.
