A 74-yeаr-оld mаn presents with prоgressive exertiоnаl shortness of breath, lower extremity edema, and lightheadedness for 7 months. He has a past medical history of HIV, hepatic cirrhosis secondary to chronic alcohol abuse and hemochromatosis, obesity, and thiamine deficiency. Symptoms improve with rest. Blood pressure 108/68 mm Hg, heart rate 90 bpm regular, oxygen saturation 92% on room air, and respirations 18/minute. The physical examination reveals rales, elevated JVP, cardiomegaly, S3 gallop rhythm, high-pitched, blowing holosystolic murmur at the apex, peripheral edema, and abdominal distension suggestive of ascites. Bedside EKG notes sinus tachycardia with non-specific ST-T wave changes and Q waves. An echocardiogram shows a dilated left ventricle, thinning of ventricular walls, and decreased systolic function.
