Initial Impression: Suspected Acute Coronary Syndrome (ACS) - likely Myocardial Infarction Justification for F2 Classification: - High probability of a life-threatening cardiac event based on classic symptoms (chest pain, radiation, diaphoresis) - Patient's risk factors (hypertension, hyperlipidemia, smoking) increase suspicion - Time-sensitive condition requiring prompt medical intervention to minimize myocardial damage Differential Diagnoses: 1. Acute Myocardial Infarction (high probability) 2. Unstable Angina (possible) 3. Aortic Dissection (less likely given presentation) 4. Pulmonary Embolism (less likely given lack of specific risk factors) 5. Musculoskeletal Chest Pain (less likely given severity and associated symptoms) Required Actions: - Dispatch of ground EMS with ALS capabilities - ECG monitoring and interpretation - Administration of oxygen and aspirin - Preparation for transport to nearest hospital with cardiac catheterization lab
