Medical Management of Peripheral Arterial Disease in Diabetes

Introduction to Management

• The European Society of Cardiology recommends aggressive cardiovascular risk reduction with statins targeting LDL-C <55 mg/dL, SGLT2 inhibitors or GLP-1 receptor agonists for glucose control, antiplatelet therapy with aspirin or clopidogrel, and meticulous foot care with daily inspection in all diabetic patients with peripheral arterial disease 1, 2

Lipid Management

• The European Society of Cardiology recommends initiating high-intensity statin therapy immediately in all diabetic patients with PAD, targeting LDL-C <1.4 mmol/L (55 mg/dL) with a >50% reduction from baseline 1, 2
• The American College of Cardiology recommends starting with maximally tolerated statin therapy as first-line treatment 1, 3
• If LDL-C target is not achieved on statin monotherapy, the European Society of Cardiology recommends adding ezetimibe 1, 2

Glucose Control

• The European Society of Cardiology prioritizes SGLT2 inhibitors or GLP-1 receptor agonists with proven cardiovascular benefit over other glucose-lowering agents, independent of baseline HbA1c 1, 2
• The European Society of Cardiology recommends targeting HbA1c <7% (53 mmol/mol) to reduce microvascular complications 1, 2

Antiplatelet Therapy

• The European Society of Cardiology recommends using aspirin 75-160 mg daily OR clopidogrel 75 mg daily as monotherapy to reduce major adverse cardiovascular events 1, 2
• The American College of Cardiology recommends aspirin (75-325 mg daily) to reduce risk of myocardial infarction, stroke, and vascular death in symptomatic PAD 4, 3, 5

Blood Pressure Management

• The European Society of Cardiology recommends targeting systolic blood pressure toward 120-129 mmHg if tolerated in diabetic patients with PAD 1, 2
• The American College of Cardiology recommends antihypertensive therapy to reduce risk of myocardial infarction, stroke, heart failure, and cardiovascular death 3, 6, 7

Foot Care and Wound Prevention

• The American College of Cardiology recommends implementing comprehensive foot care protocols with daily inspection, appropriate footwear, and immediate treatment of any skin lesions 4, 3, 5, 6, 7

Exercise Therapy

• The European Society of Cardiology recommends prescribing supervised exercise training as initial treatment for symptomatic PAD patients 1, 2

Diagnostic Monitoring

• The European Society of Cardiology recommends measuring ankle-brachial index (ABI) for initial diagnosis, and using toe pressure or toe-brachial index (TBI) if ABI is normal in diabetic patients 1, 2
• The American College of Cardiology recommends ABI measurement as essential in diabetic patients over 50 with atherosclerosis risk factors 8
