(Circ 2016;135:e686, JAMA 2021;325:2188)

• ↓ peripheral pulses, bruits;
  • signs of chronic PAD:
    • hair loss,
    • skin atrophy,
    • nail hypertrophy
• Ankle:
  • brachial index (ABI):
    • nl 1-1.4;
    • borderline 0.91-0.99;
    • abnl ≤0.90;
    • if >1.4, non-dx possibly due to calcified noncompressible vessel → ✓ PVR, TBI (toe-brachial index).
    • If ABI abnl → segmental ABI w/ PVR to localize disease.
    • If ⊕ sx but nl ABI, ✓ for ↓ lower extrem BP after exercise (≥20% ↓ in ABI w/ exercise or ≥30 mmHg ↓ in ankle pressure).
• Duplex arterial U/S;
• CTA w/ distal run-off;
• MRA or angio if dx in ? or possible intervention
