Chest. 2021 Mar;159(3):e151-e154. doi: 10.1016/j.chest.2020.09.082.

Abstract

A 64-year-old previously healthy man presented with 8 weeks of progressive dyspnea on exertion and cough. Prior to presentation, the patient was able to bicycle > 60 miles per week and work full-time in a home improvement store. He was up-to-date with age-appropriate cancer screening and immunizations, and home medications included famotidine for reflux and nonsteroidal antiinflammatories for osteoarthritis, both as-needed. He had no significant respiratory exposure, aside from previous work as an electrician. His symptoms began in mid-February 2020 amid the coronavirus disease 2019 pandemic, although he had no known exposure to the virus.
