A 63-year-old man with coronary artery disease who has recentlyundergone bypass surgery presents with dyspnea. Findings onphysical examination are unremarkable. Laboratory testing revealsa platelet count of 86,000 per cubic millimeter, as comparedwith 225,000 per cubic millimeter at the time of discharge ninedays earlier. The results of chest radiography are unremarkable;spiral computed tomography of the chest shows . . . [Full Text of this Article]
