Initial Impression: Suspected Acute ST-Elevation Myocardial Infarction (STEMI) Justification for F1 Classification: - High probability of life-threatening cardiac event based on presenting symptoms (severe crushing chest pain, radiation to left arm, shortness of breath, diaphoresis). - Time-critical condition requiring immediate intervention to minimize myocardial damage and prevent cardiac arrest. - Symptoms strongly suggest an acute coronary syndrome requiring urgent ECG and potentially emergent percutaneous coronary intervention (PCI). Differential Diagnoses: 1. Acute STEMI (high probability) 2. Unstable Angina (less likely given severity and radiation of pain) 3. Aortic Dissection (less likely given no reported back pain or tearing sensation) 4. Pulmonary Embolism (less likely given no pleuritic chest pain or hemoptysis) Required Actions: - Immediate dispatch of ground EMS with ALS capabilities - Pre-arrival instructions for patient to chew 300mg of Aspirin (if available and no contraindications) - Early notification of receiving hospital for potential PCI activation - Continuous monitoring of patient's condition and vital signs
