Initial Impression: Suspected ST-Elevation Myocardial Infarction (STEMI) Justification for F1 Classification: - Classic symptoms of acute myocardial infarction: crushing chest pain, radiation to left arm and jaw, shortness of breath, diaphoresis. - High probability of life-threatening cardiac event requiring immediate intervention. - Time-critical condition where every minute counts in preserving myocardial tissue. Differential Diagnoses: 1. STEMI (high probability) 2. Unstable Angina (less likely given severity of pain and ST-elevation) 3. Aortic Dissection (less likely given lack of tearing pain and unequal pulses) 4. Pulmonary Embolism (less likely given absence of pleuritic pain and hemoptysis) Required Actions: - Immediate dispatch of ground EMS with ALS capabilities - Pre-arrival instructions for aspirin administration if not contraindicated - Notification of hospital emergency department for potential cardiac catheterization lab activation - Continuous cardiac monitoring and ECG interpretation during transport
