John is a 76-year-old man with a long history of stable angina and hypertension. He is prescribed nitroglycerin tablets as needed for chest pain and lisinopril for his hypertension. John has noticed that his chest pain is occurring with increasing frequency and less activity is required to initiate the symptoms; however, the pain subsides quickly with rest and one or two nitroglycerin tablets.
John is awakened from sleep with chest pain and shortness of breath. The pain is much more severe than his usual anginal pain and radiates to the jaw and the left arm. He experienced some nausea and became diaphoretic and pale. Upon admission to the local emergency department, he was noted to have significant ST-segment elevation on a 12-lead electrocardiogram (ECG).
