Upon physical examination, his blood pressure is 10068 mm Hg, heart rate is 120min, respiratory rate is 23min, and temperature is 36.4C 97.5F. He is referred to the nearest hospital, where his systolic pressure drops below 90 mm Hg with an S3 gallop, and he needs inotropic support in the critical care unit. A chest radiograph shows an enlarged heart, clear lungs, and effacement of the right costodiaphragmatic angle. A subsequent esophageal echocardiogram reveals severe dilation of all heart cavities, an ejection fraction of 23, and mitral regurgitation. His family and personal history are unremarkable; therefore, an endomyocardial biopsy EMB is ordered. Which of the following microscopic findings would you expect in this specimen?? A: Infiltration with lymphocytes, B: Infiltration with eosinophils, C: Infiltration with giant cells, D: Infiltration with neutrophils, E: Infiltration with granulomas,  <response>: This is a clinical vignette describing a case of acute heart failure in a young athlete following a respiratory infection. The history and physical exam findings are consistent with acute decompensated heart failure, likely due to a cardiomyopathy. An endomyocardial biopsy is ordered to determine the underlying etiology. The correct microscopic finding in the biopsy would be lymphocytic infiltration, which is classic for viral myocarditis. Viral myocarditis can occur after viral respiratory infections and lead to acute cardiomyopathy and heart failure. Eosinophilic, giant cell, neutrophilic, and granulomatous infiltrates would point towards other etiologies like hypersensitivity reactions, sarcoidosis, acute bacterial infections, and tuberculosis respectively.A: Infiltration with lymphocytes
