38. Case # 5 A 52-year-old man telephones his physician to report a 4-week history of episodic left-sided chest pain lasting 3 to 5 minutes, often occurring at rest, and resolving spontaneously. He is unsure whether the episodes are related to meals. He has not had any shortness of breath, orthopnea, exertional dyspnea, nausea or vomiting. History is significant for hyperlipidemia. Patient has been sedentary for the past several years until 3 months ago when he began exercising. The patient is experiencing significant stress related to his job; he is also in the midst of a divorce. During the course of the phone interview, the patient is asked to determine whether he feels any pain while pressing on his chest over the lateral aspects of the sternum. The patient reports that this maneuver does vaguely reproduce his pain.
