🦵 Peripheral Artery Disease (PAD) – 2026 High-Yield ⸻ Atherosclerotic plaque narrows lower limb arteries → reduced perfusion → claudication and ↑ cardiovascular risk ❤️ For symptomatic PAD, management has evolved beyond single antiplatelet therapy. The COMPASS regimen (Rivaroxaban 2.5 mg BID + Aspirin) is now key to reduce MACE and MALE. Tight risk factor control is essential: aim for BP <130/80 mmHg (ACEi/ARB first-line) and aggressive lipid lowering with high-intensity statins, targeting LDL <55 mg/dL (≥50% reduction). Do not rely on pulses alone — ABI is the gold standard: • ≤0.90 → diagnostic of PAD • >1.40 → suggests calcified, non-compressible vessels PAD + diabetes is a high-risk combination → prioritize GLP-1 agonists or SGLT2 inhibitors to reduce cardiovascular events. Exercise is treatment: Supervised Exercise Therapy (SET) improves walking distance (30–45 min, ≥3×/week for ≥12 weeks). In advanced disease (CLTI), use the WIfI score (Wound, Ischemia, Infection) to stratify amputation risk and guide management. ⸻ 💡 Clinical Pearl Treat the limb… but always protect the heart ❤️ ⸻ 📚 High-yield cardiovascular notes are available on our website: 🌐 mediconotes.com #Cardiology #PAD #MedicalEducation #MedSchool #ClinicalMedicine
