A 26-year-old woman with no prior medical history presents to the emergency department (ED) with progressively worsening dyspnea for 1 week. Her symptoms are preceded by 3 days of fever, rigors, and nasal congestion. She is afebrile with HR of 116 beats/min and BP of 92/70 mmHg. Physical examination reveals bilateral rales, elevated jugular venous pressure, 2/6 systolic murmur at the left lower sternal border, cool extremities, and 2+ bilateral lower extremity edema. Echocardiogram reveals LVEF of 20%, nondilated LV (LV end-diastolic diameter of 3.4 cm), global hypokinesis, mild mitral regurgitation, and a normal right ventricular function. Labs are significant for creatinine of 1.6 mg/dL, aspartate aminotransferase (AST) of 385 U/L, alanine aminotransferase (ALT) of 413 U/L, troponin I of 4.8 ng/mL, and serum lactic acid of 2.8 mmol/L. Intravenous diuretics and dobutamine are initiated. Within 24 hours of admission, the patient develops hypotension and worsening heart failure refractory to inotropes and vasopressors.
