You are working in the internal medicine clinic of a large teaching hospital. Today your first patient is 70-year-old J.M., a man who has been coming to the clinic for several years for management of coronary artery disease (CAD) and hypertension (HTN).
A cardiac catheterization done a year ago showed 50
stenosis of the circumflex coronary artery. He has had episodes of dizziness for the past 6 months and
orthostatic hypotension, shoulder discomfort, and decreased exercise tolerance for the past 2 months.
On his last clinic visit 3 weeks ago, a chest x-ray (CXR) examination revealed cardiomegaly, and a 12-lead
electrocardiogram (ECG) showed sinus tachycardia with left bundle branch block (LBBB). You review J.M.'s
morning blood work and initial assessment.
