Initial Impression: Suspected Acute ST-Elevation Myocardial Infarction (STEMI) Justification for F1 Classification: - Presentation consistent with acute myocardial infarction (STEMI) with severe, crushing chest pain, radiation, shortness of breath, and diaphoresis. - Time-critical condition requiring immediate intervention to prevent irreversible myocardial damage and death. - High risk of sudden cardiac arrest. Differential Diagnoses: 1. Acute STEMI (high probability) 2. Unstable Angina (less likely given severity and radiation of pain) 3. Aortic Dissection (less likely, no tearing pain reported) 4. Pulmonary Embolism (less likely, no pleuritic pain reported) Required Actions: - Dispatch of ground EMS with ALS capabilities, including ECG monitoring - Early notification of receiving hospital with cardiac catheterization lab - Pre-hospital ECG acquisition and transmission for immediate review - Immediate initiation of oxygen and aspirin administration if no contraindications - Preparation for possible cardiac arrest and advanced life support
