1. Rule out acute coronary syndrome (ACS)

- Electrocardiogram (ECG)

- Cardiac biomarkers (e.g., troponin)

2. Consider other potential causes of chest pain

- Aortic dissection

- Pulmonary embolism

- Pericarditis

- Gastrointestinal causes (e.g., esophageal spasm)

- Musculoskeletal causes (e.g., costochondritis)

3. Initiate treatment based on suspected diagnosis

- ACS: aspirin, clopidogrel, morphine, nitroglycerin, oxygen

- Aortic dissection: immediate surgical intervention

- Pulmonary embolism: anticoagulation, oxygen, vasodilators

- Pericarditis: NSAIDs, colchicine

- Gastrointestinal causes: antacids, proton pump inhibitors

- Musculoskeletal causes: analgesics, heat/cold therapy
