Management of Peripheral Arterial Disease: Lifestyle Modifications and Medical Therapies

Abstract

<h2>Abstract</h2> Peripheral artery disease (PAD) commonly refers to atherosclerotic narrowing of noncoronary arteries, primarily those supplying the lower extremities. The risk factors for PAD include smoking, hyperlipidemia, hypertension, and diabetes mellitus. Patients with PAD are at a heightened risk of major adverse cardiovascular events (including myocardial infarction, stroke, and cardiovascular death) and major adverse limb events (including progressive symptoms or limb ischemia requiring peripheral revascularization, amputation, and acute limb ischemia), highlighting the need for guideline-directed therapies. Lifestyle modifications and medical therapies are utilized to improve function and outcomes in this patient population. Adherence to a healthy diet and smoking cessation are both associated with better outcomes in patients with PAD. Medical therapies targeting axes of risk, including lipid-modifying therapies, antithrombotic therapies, and targeted diabetes therapies, are available to reduce this risk in patients with PAD; however, significant residual risk remains. Unfortunately, despite guideline recommendations and efforts at education, even available medical therapies remain underutilized in patients with PAD. Continued development of novel therapies and efforts to improve the provision of care in patients with PAD are needed.
