Barring other concerning features for acute coronary syndrome or other life-threatening causes of chest pain (pneumothorax, pulmonary embolism, cardiac tamponade, aortic dissection, esophageal rupture, etc.), patients that meet the low-risk criteria can be considered for discharge with close follow-up with their primary care physician after negative 0h and 2h troponin testing.
Patients who do not meet the low-risk criteria should be ruled-out for myocardial infarction with serial EKGs and biomarkers and risk stratified as per normal chest pain guidelines and protocols.
- For low-risk patients: consider other causes of chest pain due to aortic, esophageal, pulmonary, cardiac, and abdominal, and musculoskeletal sources prior to discharge.
- For non-low-risk patients: Treat as per usual chest pain protocols, including but not limited to consideration of aspirin, nitroglycerin, and serial EKGs and biomarkers at minimum.
