Peripheral artery disease in diabetes.

Area of Science:

• Vascular Medicine
• Diabetology
• Cardiovascular Research

Background:

• Diabetes mellitus significantly alters peripheral artery disease (PAD) presentation and progression.
• Diabetic PAD is characterized by diffuse distal arterial disease, medial calcification, microvascular dysfunction, neuropathy, and a pro-thromboinflammatory state.
• These unique features lead to atypical presentations, diagnostic difficulties, accelerated disease, and increased risks of limb loss and cardiovascular events.

Purpose of the Study:

• To summarize the distinct clinical entity of peripheral artery disease in diabetes mellitus.
• To outline current and emerging management strategies for diabetic PAD.
• To highlight the importance of integrated approaches for improving patient outcomes.

Main Methods:

• Review of the distinct pathophysiology of PAD in diabetic patients.
• Analysis of integrated management strategies including metabolic control, lifestyle, pharmacotherapy, antithrombotics, exercise, and revascularization.
• Evaluation of emerging therapeutic approaches such as GLP-1 receptor agonists, SGLT2 inhibitors, and regenerative therapies.

Main Results:

• Diabetic PAD exhibits unique characteristics including diffuse distal disease and medial calcification.
• Current management requires a multifaceted approach addressing metabolic, vascular, and thrombotic factors.
• Novel therapies show promise for enhancing vascular function and limb salvage.

Conclusions:

• Peripheral artery disease in diabetes mellitus is a complex condition requiring specialized, integrated management.
• Optimizing metabolic control, employing evidence-based pharmacotherapy, and considering novel interventions are key to improving outcomes.
• Mechanism-driven screening and individualized treatment plans are essential for preventing complications and advancing care for diabetic PAD patients.
