Q.E., a 57-year-old white woman with a medical history significant for breast cancer, completed a 6-cycle regimen of chemotherapy including doxorubicin, docetaxel, and cyclophosphamide less than 1 week ago. She feels fatigued, which her oncologist attributes to the recent chemotherapy. Out of an abundance of caution, Q.E. is referred to a cardiologist who performs a laboratory assessment and ECHO that resulted in an NT-proBNP of 390 pg/mL [reference range <125 pg/mL] and a left ventricular ejection fraction (LVEF) of 58% and no identifiable abnormalities. Q.E. denies any symptoms of heart failure (HF) and reports being able to complete her normal activities of daily life without limitations.
