Assignment 12: Risk for coronary heart disease
The patient was a 48-year-old man admitted to the coronary care unit complaining of substernal chest pain. During the 4 months preceding admission, he noted chest pain radiating to his neck and jaw during exercise or emotional upsets. The pain dissipated when he discontinued the activity or relaxed. The results of his physical examination were essentially normal except for a systolic murmur heard best at the apex of the precordium and radiating into the left axilla.
