Initial Impression: Suspected Acute Coronary Syndrome (Non-STEMI) Justification for F2 Classification: - High probability of significant cardiac event based on classic symptoms (chest pain, radiation, diaphoresis) - Patient has multiple risk factors (hypertension, hypercholesterolemia, diabetes) - Time-sensitive condition requiring prompt medical evaluation and intervention Differential Diagnoses: 1. Acute Myocardial Infarction (Non-STEMI) (high probability) 2. Angina Pectoris (less likely given severity of symptoms) 3. Aortic Dissection (less likely, no ripping pain) 4. Pulmonary Embolism (less likely, no sudden onset of severe shortness of breath) 5. Musculoskeletal Chest Pain (less likely given radiation and associated symptoms) Required Actions: - Dispatch of ground EMS with ALS capabilities - Immediate ECG acquisition - Oxygen administration if needed - Aspirin administration if no contraindications - Preparation for transport to nearest hospital with cardiac services
