A 45-year-old male smoker comes in with a severe episode of chest pain that spreads to his left arm and jaw. The pain lasted for about half an hour before being relieved by GTN spray and aspirin. A troponin test is done 12 hours later, which comes back positive. His ECG at the time of presentation reveals widespread ST depression.

What is the MOST LIKELY diagnosis in this case?
