The increased risk of atherothrombotic events present in all patients with peripheral arterial disease (PAD) is amplified with concomitant diabetes. Moreover, diabetes is associated with increased PAD severity. This Review summarizes atherothrombosis and PAD in patients with diabetes, and American College of Cardiology and American Heart Association guidelines for management of patients with PAD. Patients with PAD and diabetes require optimal limb care and aggressive cardiovascular risk reduction. An LDL cholesterol level of less than 1.8 mmol/l (<70 mg/dl) is the therapeutic goal in these patients, and this target should be pursued using an aggressive statin regimen. Fibrate therapy can also be indicated. beta-blockers and angiotensin-converting-enzyme inhibitors reduce cardiovascular events in high-risk patient populations, and these agents are recommended for use in patients with both diabetes and PAD. Blood pressure of less than 130/80 mmHg should be achieved, and glycated hemoglobin should be reduced to below 7%. Patients should also receive indefinite antiplatelet therapy with aspirin or clopidogrel. For patients with claudication, a supervised exercise program and cilostazol therapy to improve PAD symptoms and walking distance form the main noninvasive components of therapy. Revascularization can also be indicated in carefully selected patients with claudication. For patients with critical limb ischemia, diagnostic testing by a vascular specialist will determine whether revascularization or amputation is feasible.
