A 56-year-old man presents to the emergency department with substernal chest pain and describes it as "pressure-like." This chest pain worsens with exertion and improves with rest. He denies any lightheadedness, palpitations, or syncopal episodes. He has a medical history of hypertension and hyperlipidemia. He currently takes lisinopril and has stopped taking lovastatin due to muscle pain. In the emergency department, his blood pressure is 135/85 mmHg, pulse is 102/min, and respirations are 18/min. Cardiac auscultation is remarkable for an extra heart sound right after S2. Radiography of the chest is shown in Figure A, and electrocardiogram demonstrates ST depression in V1-4. Laboratory studies are shown below:
