In Episode 57 of Med School Question of the Week for USMLE, Faustine Ramirez, MedSchoolCoach expert tutor, answers this medical school question: A 72-year-old man presents to the emergency department an hour after the onset of severe chest pain radiating to the back. The pain started suddenly while he was gardening. He has a history of hypertension, coronary artery disease, and prior myocardial infarction. He has smoked one pack of cigarettes per day for as long as he can remember. He appears in moderate distress. Heart rate is 108/min, respiratory rate is 22/min, and blood pressure is 168/102. A grade 2/6 diastolic decrescendo murmur is heard at the right upper sternal border and intensifies when the patient is sitting up and leaning forward. A chest x-ray is shown here. Electrocardiogram shows sinus tachycardia and no ST-segment elevations. Which of the following is the most appropriate initial step in pharmacotherapy?
