Initial Impression: Suspected Acute ST-Elevation Myocardial Infarction (STEMI) Justification for F1 Classification: - Severe, crushing chest pain with radiation and associated symptoms is highly suggestive of a STEMI - Time-critical condition requiring immediate intervention to minimize myocardial damage - Presence of diaphoresis, shortness of breath, and nausea further increases suspicion of cardiac event Differential Diagnoses: 1. Acute Myocardial Infarction (STEMI - highest probability) 2. Unstable Angina (less likely given severity of pain and associated symptoms) 3. Aortic Dissection (lower probability, no reported tearing pain) 4. Pulmonary Embolism (lower probability, no reported pleuritic chest pain) Required Actions: - Dispatch of ground EMS with ALS capabilities - Immediate ECG acquisition and transmission - Activation of local STEMI protocol - Preparation for transport to nearest hospital with PCI capabilities - Early notification of hospital emergency department and cardiology team
