Initial Impression: Suspected Acute ST-Elevation Myocardial Infarction (STEMI) Justification for F1 Classification: - Presence of severe, crushing chest pain radiating to left arm and jaw. - Associated symptoms of shortness of breath, diaphoresis, and nausea. - High probability of acute myocardial infarction based on presentation. - Time-critical condition requiring immediate intervention to prevent irreversible cardiac damage and potential cardiac arrest. Differential Diagnoses: 1. Acute STEMI (high probability) 2. Unstable Angina (less likely given severity and radiating pain) 3. Aortic Dissection (less likely, no tearing pain reported) 4. Pulmonary Embolism (less likely given pain characteristics) Required Actions: - Immediate dispatch of ground EMS with ALS capabilities, including ECG capability. - Pre-arrival instructions for patient to chew and swallow 300mg of Aspirin if available. - Rapid transport to nearest hospital with PCI (Percutaneous Coronary Intervention) capabilities. - Early notification of hospital to prepare for potential primary PCI.
