Cardiovascular Disease: Lower Extremity Peripheral Artery Disease

Area of Science:

• Vascular Medicine
• Cardiovascular Disease
• Public Health

Background:

• Lower extremity peripheral artery disease (PAD) is a common manifestation of atherosclerosis affecting millions in the US.
• Key risk factors include advanced age, hypertension, dyslipidemia, diabetes, and smoking.
• PAD presents with diverse symptoms, from intermittent claudication to asymptomatic disease, impacting diagnosis and management.

Purpose of the Study:

• To provide a comprehensive overview of peripheral artery disease (PAD) affecting the lower extremities.
• To outline diagnostic approaches and therapeutic strategies for PAD.
• To highlight the importance of risk factor modification and timely intervention.

Main Methods:

• Review of current medical literature and clinical guidelines for PAD.
• Description of diagnostic tools, including ankle-brachial index, duplex ultrasonography, and angiography.
• Summary of therapeutic interventions, encompassing lifestyle modifications, medical management, and revascularization procedures.

Main Results:

• PAD affects 8-12 million Americans, with varying clinical presentations.
• Ankle-brachial index is the primary diagnostic test for suspected PAD.
• Treatment strategies are tailored to disease severity, including lifestyle changes, antiplatelet/statin therapy, and revascularization.

Conclusions:

• Effective management of PAD requires a multi-faceted approach, including risk factor control and appropriate therapeutic interventions.
• Early diagnosis and treatment are crucial for preventing severe complications like acute limb ischemia.
• Revascularization should be considered for patients with lifestyle-limiting symptoms or chronic limb ischemia.
