Peripheral Artery Disease (PAD) results from narrowed arteries that reduce blood flow to the limbs, typically affecting the legs. The stages of PAD include asymptomatic, claudication, critical limb ischemia (rest pain), and acute limb ischemia. Peripheral Artery Disease treatment strategies encompass lifestyle modifications, medications, and interventions like angioplasty or bypass surgery to improve circulation. Early diagnosis and treatment are essential to avoid complications.
