Initial Impression: Suspected Acute ST-Elevation Myocardial Infarction (STEMI) Justification for F1 Classification: - Classic presentation of STEMI with severe chest pain, radiation, diaphoresis, and shortness of breath. - Time-critical condition requiring immediate intervention to prevent significant morbidity and mortality. - High risk of cardiac arrest without prompt treatment. Differential Diagnoses: 1. STEMI (high probability) 2. Unstable Angina (less likely given severity of pain and associated symptoms) 3. Aortic Dissection (less likely given absence of tearing pain and pulse deficits) 4. Pulmonary Embolism (less likely given lack of pleuritic chest pain and hemoptysis) Required Actions: - Immediate dispatch of ground EMS with ALS capabilities. - Pre-hospital 12-lead ECG to confirm STEMI and transmit to hospital. - Early notification of the receiving hospital (FSA) for activation of the cardiac catheterization lab. - Administration of oxygen, aspirin, and nitrates if appropriate.
