Studies have not evaluated presence of abnormal cardiac structure and function before scanning in setting of COVD-19 infection. We sought to examine cardiac abnormalities in consecutive group of patients with acute COVID-19 infection according to the presence or absence of cardiac disease based on review of health records and cardiovascular imaging studies. We looked at independent contribution of imaging findings to clinical outcomes. After excluding patients with previous left ventricular (LV) systolic dysfunction (global and\/or segmental), 724 patients were included. Machine learning identified predictors of in-hospital mortality and in-hospital mortality\u2009+\u2009ECMO. In patients without previous cardiovascular disease, LV EF\u2009&lt;\u200950% occurred in 3.4%, abnormal LV\u00a0global longitudinal strain (&lt;\u200916%) in 24%, and diastolic dysfunction in 20%. Right ventricular systolic dysfunction (RV free wall strain\u2009&lt;\u200920%) was noted in 18%. Moderate and large pericardial effusion were uncommon with an incidence of 0.4% for each category. Forty patients received ECMO support, and 79 died (10.9%). A stepwise increase in AUC was observed with addition of vital signs and laboratory measurements to baseline clinical characteristics, and a further significant increase (AUC 0.91) was observed when echocardiographic measurements were added. The performance of an optimized prediction model was similar to the model including baseline characteristics\u2009+\u2009vital signs and laboratory results\u2009+\u2009echocardiographic measurements.<\/jats:p>","DOI":"10.1038\/s41598-021-98773-4","type":"journal-article","created":{"date-parts":[[2021,9,30]],"date-time":"2021-09-30T10:30:41Z","timestamp":1632997841000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Cardiac involvement in hospitalized patients with COVID-19 and its incremental value in outcomes prediction"],"prefix":"10.1038","volume":"11","author":[{"given":"Payam","family":"Pournazari","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alison L.","family":"Spangler","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fawzi","family":"Ameer","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kobina K.","family":"Hagan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mauricio E.","family":"Tano","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohammed","family":"Chamsi-Pasha","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lakshmi H.","family":"Chebrolu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"William A.","family":"Zoghbi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Khurram","family":"Nasir","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sherif F.","family":"Nagueh","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2021,9,30]]},"reference":[{"key":"98773_CR1","doi-asserted-by":"publisher","first-page":"2287","DOI":"10.1016\/j.jcmg.2020.04.014","volume":"13","author":"Y Li","year":"2020","unstructured":"Li, Y. et al.
