Initial Impression: Suspected Acute ST-Elevation Myocardial Infarction (STEMI) Justification for F1 Classification: - Severe chest pain, radiating to left arm and jaw, associated with shortness of breath and diaphoresis - High probability of an acute cardiac event - Time-critical condition requiring immediate intervention to minimize myocardial damage Differential Diagnoses: 1. Acute STEMI (high probability) 2. Unstable Angina (less likely given severity of pain and associated symptoms) 3. Aortic Dissection (less likely, no tearing pain) 4. Pulmonary Embolism (less likely, no pleuritic pain or hemoptysis) Required Actions: - Dispatch of ground EMS with ALS capabilities - Immediate ECG acquisition and transmission to hospital - Pre-hospital treatment protocols initiation (oxygen, aspirin, nitrates if indicated) - Rapid transport to nearest hospital with PCI capabilities - Early hospital notification for activation of cardiac catheterization lab
