Management Plan for Peripheral Artery Disease (NAC OSCE Station)

All patients with PAD require lifelong guideline-directed medical therapy (GDMT) to prevent major adverse cardiovascular events (MACE) and major adverse limb events (MALE), regardless of whether they undergo revascularization 1.

Immediate Assessment & Risk Stratification

Key History Elements

  • Claudication symptoms: Walking distance, rest pain, tissue loss
  • Cardiovascular risk factors: Smoking status, diabetes, hypertension, dyslipidemia
  • Functional status: Impact on quality of life and daily activities
  • Previous revascularization: Timing and type of procedures

Physical Examination Focus

  • Pulse assessment: Femoral, popliteal, dorsalis pedis, posterior tibial
  • Foot inspection: Ulcers, gangrene, skin changes, temperature
  • ABI measurement: <0.90 confirms PAD diagnosis

Medical Management (Core GDMT)

1. Antithrombotic Therapy

  • Dual pathway inhibition: Low-dose rivaroxaban (2.5 mg BID) + aspirin (81 mg daily) for high ischemic risk patients with non-high bleeding risk 2
  • Alternative: Clopidogrel 75 mg daily if dual therapy contraindicated

2. Lipid Management

  • Statin therapy: High-intensity statin for all PAD patients (first-line) 1, 2
  • LDL-C target: <1.4 mmol/L (<55 mg/dL)
  • Add-on therapy if target not met: Ezetimibe → bempedoic acid → PCSK9 inhibitors 2

3. Blood Pressure Control

  • Target: <130/80 mmHg
  • Avoid: Beta-blockers as first-line (may worsen claudication)

4. Diabetes Management

  • Preferred agents: GLP-1 receptor agonists or SGLT2 inhibitors (cardiovascular and potential limb benefits) 2
  • HbA1c target: <7% (individualized)

5. Smoking Cessation

  • Mandatory intervention: Counseling + pharmacotherapy (varenicline, bupropion, or nicotine replacement)

Functional Rehabilitation

Supervised Exercise Therapy

  • Prescription: 30-45 minutes, 3 times weekly, minimum 12 weeks
  • Type: Walking to near-maximal claudication pain, then rest, repeat
  • Goal: Improve walking distance and quality of life 1

Follow-Up Protocol

Routine Surveillance (No Revascularization)

  • Frequency: At least annually 3
  • Assessment: Clinical status, functional capacity, medication adherence, pulse exam, foot inspection
  • ABI/duplex: As clinically indicated for symptom changes

Post-Revascularization Surveillance

For endovascular or vein bypass patients 1:

  • 1-3 months: ABI + arterial duplex ultrasound
  • 6 months: Repeat ABI + duplex
  • 12 months: Repeat ABI + duplex
  • Annually thereafter: Continue surveillance

If new symptoms develop: Immediate ABI + duplex ultrasound 1

Revascularization Indications

Proceed with Revascularization

  • Chronic limb-threatening ischemia (CLTI): Rest pain, tissue loss, gangrene - revascularize urgently for limb salvage 3
  • Lifestyle-limiting claudication: Despite optimal medical therapy and supervised exercise failure

Do NOT Revascularize

  • Asymptomatic PAD: No indication 3
  • Mild claudication: Trial medical therapy + exercise first
  • Prevention alone: Revascularization does not prevent progression to CLTI 3

Coordination of Care

Multidisciplinary team involvement 1:

  • Primary care for risk factor management
  • Vascular specialist for limb assessment
  • Endocrinology for complex diabetes
  • Podiatry for foot care in high-risk patients

Critical Pitfalls to Avoid

  • Undertreatment: PAD patients require the same aggressive cardiovascular risk reduction as post-MI patients
  • Delayed CLTI recognition: Any rest pain or tissue loss requires urgent vascular referral 3
  • Premature revascularization: Asymptomatic patients should never be revascularized 3
  • Inadequate lipid control: Statins alone often insufficient; use combination therapy to reach LDL-C targets 2
  • Missing post-procedure surveillance: Early detection of graft/stent failure improves outcomes 1
