A 53-year-old man with chest pain was referred to undergo an exercise treadmill test (ETT). He reported substernal chest pain, lasting less than 5 minutes, which sometimes occurred if he ran more than 2 miles. He had no other symptoms.
The patient's medical history included hypertension (controlled with lisinopril and hydrochlorothiazide), a low-density lipoprotein level of 155 mg/dL, and a high-density lipoprotein level of 44 mg/dL. He did not smoke or have family history of premature coronary artery disease (CAD). The patient’s physical examination results were unremarkable, blood pressure was 134/80 mm Hg, body mass index was 26 (calculated as weight in kilograms divided by height in meters squared), and resting electrocardiogram (ECG) results were normal.
