Peripheral Artery Disease
Peripheral artery disease (PAD) is a medical condition caused by narrowing or blockage of the arteries that supply blood to the extremities. It occurs when fatty deposits, also known as plaque, build up in the arteries, reducing the amount of blood flowing to the limbs. Symptoms of PAD can range from leg pain and cramping to muscle pain, coldness in the feet or toes, and changes in skin color. Left untreated, PAD can lead to complications such as stroke, transient ischemic attacks, and even the need for amputation. PAD is primarily diagnosed using Doppler imaging and angiography. Treatment for PAD includes lifestyle changes such as quitting smoking, exercising regularly, and eating a healthy diet. Medications, such as statins and antiplatelet drugs, as well as angioplasty and/or stenting may also be required. PAD is an important public health issue as it is a risk factor for heart attack, stroke, and other cardiovascular diseases. Early detection and treatment are essential for improving the prognosis of PAD patients.
