Initial Impression: Suspected Acute ST-Elevation Myocardial Infarction (STEMI) Justification for F1 Classification: - Severe chest pain with radiation, shortness of breath, diaphoresis, and nausea, strongly suggestive of acute myocardial infarction. - Time-critical condition requiring immediate intervention to prevent irreversible myocardial damage and life-threatening complications. - Symptoms and presentation meet criteria for F1 priority. Differential Diagnoses: 1. Acute STEMI (high probability) 2. Unstable Angina (less likely given severity of symptoms) 3. Aortic Dissection (less likely given lack of tearing pain) 4. Pulmonary Embolism (less likely given absence of pleuritic chest pain) 5. Pericarditis (less likely given the radiating pain) Required Actions: - Immediate dispatch of ground EMS with ALS capabilities. - Pre-hospital ECG acquisition and interpretation. - Early notification of receiving hospital with PCI capabilities. - Preparation for immediate transport to nearest hospital with cardiac catheterization lab.
