A 60 year old diabetic male presents to OPD with complaints of central chest pain for last 2 hours. Pain is radiating to left arm. ECG normal and Troponins are negative. Further approach?
👉 High suspicion for ACS despite normal tests
⚠️ Key Principle
❗ Normal ECG + Negative Troponin does NOT rule out MI (early phase) Especially in elderly diabetics (often atypical/silent ischemia).
urther Approach 1️⃣ Treat as Possible ACS
👉 Start protocol if no contraindication:
💊 Aspirin 150–300 mg (chewed) 💊 Statin (High-intensity) 💊 Nitrates (if BP stable) 💊 Oxygen (if SpO₂ < 90%) 💊 Beta-blocker (if indicated) 2️⃣ Serial Monitoring (Mandatory) 📈 Repeat: ✔️ ECG every 15–30 min ✔️ Troponin at 3–6 hours (Use hs-Troponin protocol if available) 3️⃣ Risk Stratification 📊 Use HEART / TIMI score High-risk → Admit 4️⃣ Imaging 🫀 2D Echo → RWMA 🫀 If stable → Stress test / CT Coronary Angio 🫀 If positive → Coronary Angiography 5️⃣ Admit for Observation 👉 Minimum 24 hours in monitored setting 🚨 Indications for Urgent Cath / ICU ⚠️ Persistent pain ⚠️ Dynamic ECG changes ⚠️ Rising troponin ⚠️ Hemodynamic instability Important Differentials 1: NSTEMI / Unstable Angina 2: Aortic dissection 3: Pulmonary embolism 4: GERD / Esophageal spasm 5: Costochondritis
Nice update
