Initial Impression: Suspected ST-Elevation Myocardial Infarction (STEMI) Justification for F1 Classification: - High probability of acute myocardial infarction based on classic symptoms (crushing chest pain, radiation, diaphoresis, shortness of breath) - Time-critical condition requiring immediate intervention (fibrinolysis or primary PCI) - High risk of life-threatening complications (arrhythmias, cardiac arrest) Differential Diagnoses: 1. STEMI (high probability) 2. Unstable Angina (less likely given severity of pain and ST elevation) 3. Aortic Dissection (less likely, no tearing pain) 4. Pulmonary Embolism (less likely, no pleuritic pain) Required Actions: - Immediate dispatch of ground EMS with ALS capabilities - Pre-hospital ECG acquisition and interpretation - Early hospital notification for activation of cardiac catheterization lab - Oxygen administration and IV access - Administration of aspirin and other medications per protocol
