The impact of SARS-CoV-2 on the heart during the Omicron pandemic is not yet fully elucidated.\nMethodology: We conducted a retrospective cohort study of 1,026 hospitalized patients with the Omicron variant at Southwest Hospital (December 2022 to March 2023). Adverse events were defined as a composite of all-cause mortality, intensive care unit admission, mechanical ventilation use, and discharge against medical advice. The risk factors were analyzed by Logistic regression and the Cox regression model.\nResults: Median age was 69 years (IQR 56\u201379), myocardial injury occurred in 54.7% (n = 561); adverse events occurred in 25.5% (n = 262). The risk factors of myocardial injury included older age (OR 1.04 [1.03, 1.05], p &lt; 0.001), body temperature at admission (OR 1.64 [1.19, 2.29], p = 0.003), critical COVID-19 (OR 4.96 [2.34, 11.54], p &lt; 0.001), severe valvular heart disease (OR 2.46 [1.06, 6.12], p = 0.042), renal insufficiency (OR 4.04 [2.75, 6.01], p &lt; 0.001), anemia (OR 3.10 [2.12, 4.58], p &lt; 0.001), type II respiratory failure (OR 5.54 [1.79, 24.39], p = 0.008) and higher white blood cell (OR 1.09 [1.05, 1.14], p &lt; 0.001). After adjustment, myocardial injury (HR 1.79 [1.28, 2.48], p = 0.001) was significantly associated with adverse events in patients with Omicron variant infection.\nConclusions: Myocardial injury, the most common extrapulmonary complication of COVID-19 caused by the SARS-CoV-2 Omicron variant, requires timely attention to prevent adverse events in hospitalized patients.<\/jats:p>","DOI":"10.3855\/jidc.21008","type":"journal-article","created":{"date-parts":[[2026,2,9]],"date-time":"2026-02-09T18:07:48Z","timestamp":1770660468000},"page":"19-28","source":"Crossref","is-referenced-by-count":0,"title":["Patients with SARS-CoV-2 Omicron variant infection complicated with myocardial injury: a retrospective cohort study"],"prefix":"10.3855","volume":"20","author":[{"given":"Juanjuan","family":"Zheng","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lingyan","family":"Liu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jiamin","family":"Zou","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cheng","family":"Liang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuming","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hong","family":"Peng","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wenyou","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yangyang","family":"Zhou","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wei Eric","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2222","published-online":{"date-parts":[[2026,1,31]]},"container-title":["The Journal of Infection in Developing Countries"],"original-title":[],"link":[{"URL":"https:\/\/www.jidc.org\/index.php\/journal\/article\/download\/21008\/3801","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.jidc.org\/index.php\/journal\/article\/download\/21008\/3801","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,2,9]],"date-time":"2026-02-09T18:07:49Z","timestamp":1770660469000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.jidc.org\/index.php\/journal\/article\/view\/21008"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,1,31]]},"references-count":0,"journal-issue":{"issue":"01","published-online":{"date-parts":[[2026,1,31]]}},"URL":"https:\/\/doi.org\/10.3855\/jidc.21008","relation":{},"ISSN":["1972-2680"],"issn-type":[{"value":"1972-2680","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,1,31]]}}}
