A 54-year-old man presents with sudden severe central chest pain for 2 hours. The pain does not radiate, and is not exacerbated or relieved by changes in posture. He also experienced nausea, vomiting, and sweating.

His medical, surgical, and family histories are unremarkable. He does not smoke and only drinks socially. A routine health evaluation a month ago showed his fasting blood glucose, lipid profile, renal functions, and liver functions to all be within normal parameters.
