The coronavirus disease 2019 (COVID-19) pandemic has affected presentations of conditions unrelated to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection itself. We investigated the pandemic's effect on incidence and characteristics of pulmonary embolism (PE) cases without the infection. We retrospectively compared non-COVID PE patients during January 16-August 31, 2020 (COVID period) with PE patients during the same period in 2017-2019 (Pre-COVID period). The number of out-of-hospital onset cases was significantly higher during the pandemic than during each of the pre-COVID years. Also, the patients in the COVID period were older, more likely to be free of thrombotic predispositions, had higher mortality risks of PE, and were more likely to arrive at the hospital on emergency transport. Sedentary lifestyles during the pandemic seem to have had considerable effects on presentations of PE.
