Abstract
A 72 YEAR-OLD, 70-kg, 170-cm man presented to the authors' institution for evaluation of progressively worsening chest pain and tightness that were relieved by rest. These chest symptoms were located throughout his anterior chest but did not radiate to his jaw, left shoulder, or back. His symptoms were accompanied by pronounced dyspnea on exertion, easy fatigability, and orthostatic near syncope. Medical treatment with calcium channel and β1-adrenoceptor antagonists (diltiazem and metoprolol, respectively) failed to substantially improve his symptoms.
