Updated guideline for management of lower extremity peripheral artery disease
Updated guideline for management of lower extremity peripheral artery disease Lower extremity peripheral artery disease (PAD) is a common circulatory problem characterized by narrowing or blockage of the arteries that supply blood to the legs and feet. It often results from atherosclerosis, where plaque buildup leads to reduced blood flow, causing symptoms such as claudication, rest pain, and in severe cases, tissue loss or gangrene. Recent updates in the guidelines for managing PAD emphasize a comprehensive, patient-centered approach that integrates risk factor modification, medical therapy, and, when necessary, revascularization procedures.
The cornerstone of management remains the control of cardiovascular risk factors, including smoking cessation, blood pressure management, lipid control, and diabetes management. Evidence suggests that a structured lifestyle intervention, particularly supervised exercise therapy, significantly improves walking distance and quality of life in patients with intermittent claudication. Patients are encouraged to participate in supervised exercise programs, typically involving walking to near-maximum pain levels, three times weekly, for at least 30-45 minutes per session.
Pharmacotherapy plays a vital role in symptom relief and limb preservation. Antiplatelet agents, such as aspirin or clopidogrel, are recommended to reduce the risk of cardiovascular events. For patients with more severe symptoms, vasodilators are generally not recommended due to limited evidence of benefit. Instead, cilostazol, a phosphodiesterase inhibitor, is approved for improving walking distance in intermittent claudication, although its use must be individualized considering contraindications like heart failure.

Lipid management has gained prominence, with statins being strongly recommended to lower low-density lipoprotein (LDL) cholesterol levels, thereby reducing atherosclerotic progression and cardiovascular risk. Achieving target LDL levels, often <70 mg/dL, is associat
ed with better limb and cardiovascular outcomes. Blood pressure control, with a target often below 130/80 mm Hg, is equally emphasized. Updated guideline for management of lower extremity peripheral artery disease
Updated guideline for management of lower extremity peripheral artery disease When conservative measures are insufficient, revascularization strategies are considered. Endovascular interventions, such as angioplasty and stenting, are preferred initially for most lesions, owing to their minimally invasive nature and favorable recovery profile. Surgical bypass is reserved for complex or extensive disease not amenable to endovascular therapy. The decision between medical management and revascularization relies on symptom severity, lesion characteristics, and the patient’s overall health status.
Updated guideline for management of lower extremity peripheral artery disease The updated guidelines underline the importance of a multidisciplinary approach, involving vascular specialists, cardiologists, and primary care providers, to optimize outcomes. Additionally, careful follow-up is necessary to monitor disease progression, manage comorbidities, and address potential complications. Preventive measures, including smoking cessation, exercise, and pharmacotherapy, remain the pillars of long-term management, aiming not only to relieve symptoms but also to improve survival and limb preservation.
Updated guideline for management of lower extremity peripheral artery disease In summary, the management of lower extremity PAD has evolved to focus on personalized treatment plans that integrate lifestyle modification, pharmacotherapy, and timely revascularization when indicated. Adherence to these guidelines can significantly improve patient quality of life and reduce the risk of major cardiovascular and limb events.
