man was referred for an abnormality detected on a routine
preoperative chest radiograph (for ophthalmological surgery). He had a
history notable for a myocardial infarction that occurred 18 years ago,
followed 1 year later by a four-vessel coronary artery bypass graft
(CABG). The patient was symptom-free until 1 year ago, when mild angina
symptoms recurred. He was a smoker known to have arterial
hypertension, hyperlipidemia, and peptic ulcer disease, which were well
controlled with appropriate medication. There was no history of trauma.
The physical examination was not contributory.
