No Loeffing Matter: The Dilemma of Loeffler's Endocarditis

Published:October 10, 2019DOI:https://doi.org/10.1016/j.amjmed.2019.08.053
      A 69-year-old woman presented to the Emergency Department with 1 week of progressively worsening shortness of breath. The dyspnea worsened with exertion and was alleviated with rest. Associated symptoms included orthopnea, lower-extremity edema, and weight gain. Her medical history consisted of emphysema and hypothyroidism with no prior cardiac history. Her home medications were levothyroxine, an albuterol rescue inhaler, and tiotropium. She had no past surgeries and no family history of cardiac disease. The patient had a long history of cigarette smoking but no alcohol or illicit drug use. She has never traveled outside the country.
