What is Peripheral Artery Disease?

Peripheral Artery Disease (PAD) is a common circulatory condition where narrowed arteries reduce blood flow to the limbs, most often the legs. It is primarily caused by atherosclerosis, the buildup of fatty plaque inside artery walls. Key facts: PAD affects over 200 million people worldwide, and critical limb ischemia (CLI) is its most severe form, carrying a high risk of amputation if untreated. Early diagnosis and intervention can significantly improve outcomes and quality of life.
