The peripheral artery disease statpearls Peripheral artery disease (PAD) is a common circulatory problem characterized by the narrowing or blockage of arteries outside the heart and brain, predominantly affecting the arteries supplying the legs and feet. This condition results from atherosclerosis, where fatty deposits build up on the arterial walls, leading to reduced blood flow. PAD is significant because it can cause pain, mobility issues, and, if left untreated, serious complications like limb ischemia or even amputation.
Understanding the epidemiology of PAD reveals its widespread impact. It is estimated that over 200 million people worldwide suffer from PAD, with prevalence increasing with age. Risk factors include smoking, diabetes mellitus, hypertension, hyperlipidemia, obesity, and a sedentary lifestyle. Notably, PAD often coexists with coronary artery disease and cerebrovascular disease, reflecting its systemic nature. The condition is underdiagnosed, partly because many patients are asymptomatic or have atypical symptoms, making screening and early detection crucial. The peripheral artery disease statpearls
Clinically, PAD manifests primarily through symptoms like intermittent claudication—muscle pain or cramping in the legs during activity that subsides with rest. As the disease progresses, patients may experience rest pain, non-healing wounds, cold or pale extremities, and diminished or absent pulses in the affected limbs. These signs are important clues and should prompt further evaluation. The peripheral artery disease statpearls
Diagnosis of PAD involves a combination of patient history, physical examination, and non-invasive testing. The ankle-brachial index (ABI) is a simple, reliable test comparing blood pressure in the ankle with that in the arm; an ABI below 0.90 typically indicates PAD. Additional imaging modalities such as duplex ultrasonography, computed tomography angiography (CTA), and magnetic resonance angiography (MRA) provide detailed visualization of arterial obstructions, aiding in planning treatment strategies.

Management of PAD aims to alleviate symptoms, improve quality of life, and reduce cardiovascular risk. Lifestyle modifications are fundamental, including smoking cessation, engaging in supervised exercise programs, and controlling comorbid conditions like diabetes and hypertension. Pharmacologically, antiplatelet agents such as aspirin or clopidogrel help prevent clot formation, while statins reduce lipid levels and stabilize atherosclerotic plaques. In cases where lifestyle and medication do not suffice, endovascular interventions such as angioplasty and stenting or surgical bypass procedures may be necessary to restore adequate blood flow.

Regular screening for at-risk populations, patient education, and adherence to medical therapy contribute significantly to improved outcomes. Despite advances in diagnosis and treatment, PAD remains a marker of systemic atherosclerosis, necessitating a comprehensive approach to cardiovascular risk reduction.
In conclusion, peripheral artery disease is a prevalent, yet often underrecognized condition with serious implications. A multidisciplinary approach involving lifestyle modification, medical therapy, and interventional procedures can effectively manage symptoms and reduce the risk of adverse cardiovascular events. Increased awareness and early detection are vital for better patient outcomes and quality of life. The peripheral artery disease statpearls
