Patient B is 42 years of age and works as a newspaper editor. He presents to the emergency department complaining of chest pain radiating into both arms, accompanied by diaphoresis and shortness of breath. He has been having episodes of transient substernal and shoulder pain over the past week. He is admitted to the CCU.
Patient B is being treated for hypertension and is currently taking 100 mg metoprolol twice per day. He does not exercise and has smoked a pack of cigarettes daily for 20 years. He reports being under considerable job stress. He is overweight, with a body mass index of 35.
Upon admittance to the CCU, a full physical exam is conducted (Table 5). An ECG shows ST segment depression and T wave inversion consistent with subendocardial ischemia in the inferior and anterior leads. An incomplete left bundle branch block is also noted. Laboratory studies (CBC, urinalysis, and cardiac isoenzyme levels) are all within normal limits, although cardiac isoenzymes are in the upper range.

Based on the results of the assessment, Patient B is diagnosed with:
Patient B stays in the CCU for three days. During that time, serum cardiac enzyme levels and repeat ECGs confirm a diagnosis of subendocardial ischemia rather than MI. Coronary artery angiography is done to clarify the coronary artery anatomy and finds a 35% to 45% occlusion of the left anterior descending artery. The possibility of coronary artery vasospasm is not excluded because no ergonovine trial is done. Repeat evaluation for coronary artery bypass surgery is planned for the future, with conservative medical treatment in the interim.
At discharge, Patient B is prescribed:
