Initial Impression: Suspected Acute ST-Elevation Myocardial Infarction (STEMI) Justification for F1 Classification: - Severe, crushing chest pain with radiation, diaphoresis, and shortness of breath are highly indicative of a STEMI. - History of previous MI significantly increases risk. - Time-critical condition requiring immediate intervention to prevent myocardial damage and potential death. Differential Diagnoses: 1. STEMI (high probability) 2. Unstable Angina (less likely given severity and radiation of pain) 3. Aortic Dissection (less likely given absence of tearing pain) 4. Pulmonary Embolism (less likely given absence of pleuritic pain and hemoptysis) Required Actions: - Immediate dispatch of ground EMS with ALS capabilities. - Early notification to nearest PCI-capable hospital. - Pre-hospital ECG acquisition and transmission if possible. - Initiate oxygen therapy and aspirin administration if not already taken. - Prepare for immediate transport to hospital for PCI.
