Initial Impression: Suspected Acute ST-Elevation Myocardial Infarction (STEMI) Justification for F1 Classification: - High probability of life-threatening cardiac event based on classic STEMI symptoms (crushing chest pain, radiation, diaphoresis, shortness of breath). - History of previous MI increases the risk of current acute coronary syndrome. - Time-critical condition requiring immediate medical intervention to limit myocardial damage. Differential Diagnoses: 1. Acute STEMI (high probability) 2. Unstable Angina (less likely given severity of pain and lack of relief with nitroglycerin) 3. Aortic Dissection (less likely given lack of ripping or tearing pain) 4. Pulmonary Embolism (less likely given lack of pleuritic pain and no known risk factors) Required Actions: - Immediate dispatch of ground EMS with ALS capabilities. - Pre-arrival instructions for aspirin administration if not already taken. - Early hospital notification for activation of cardiac catheterization lab. - Preparation for 12-lead ECG acquisition and potential fibrinolytic therapy.
