Patient presents with ACS symptoms 1. ECG - ST elevation or new LBBB, then STEMI 2. If no ST elevation, do troponin 3. Raised troponin and/or other ECG changes such as: ST depression T wave inversion Pathological Q waves DIAGNOSIS IS NSTEMI 4. Troponin levels normal and ECG no changes - unstable angina, or another cause e.g. MSK pain
