Methods: We retrospectively searched medical records to screen hospitalized patients with MG at our hospital. The troponin T (TnT) levels were deemed necessary to be performed based on the patient\u2019s clinical symptoms and were used as biomarkers of myocardial injury. The patients\u2019 demographic and clinical information were collected. Death was the primary outcome. Results: A total of 336 patients with MG measured TnT levels and were included in the final analysis. The male MG patients with elevated TnT levels had a higher prevalence of infection (56.8% vs. 30.0%, p = 0.001) and myasthenic crisis (37.5% vs. 13.3%, p = 0.001) than those with normal TnT levels. Meanwhile, the female MG patients with elevated TnT levels were older (56.0 (16.6) vs. 49.2 (17.2)) years old, p = 0.007] and had a higher prevalence of infection (65.4% vs. 32.1%, p &lt; 0.001), myasthenic crisis (33.6% vs. 17.9%, p = 0.015), and thymoma (38.5% vs. 16.7%, p = 0.001) than those with normal TnT levels. Older age (coef. = 0.004; p = 0.034), infection (coef. = 0.240; p = 0.001), myasthenic crisis (coef. = 0.312; p &lt; 0.001), thymoma (coef. = 0.228; p = 0.001), and ICI therapy (coef. = 1.220; p &lt; 0.001) were independent risk predictors for increasing log TnT levels. Thirty-seven patients died during hospitalization. High log TnT levels (OR = 8.818; p &lt; 0.001), female sex (OR = 0.346; p = 0.023), thymoma (OR = 5.092; p = 0.002), and infection (OR = 14.597; p &lt; 0.001) were independent risk predictors of death. Conclusions: Our study revealed that the surveillance of myocardial injury biomarkers in MG patients might be beneficial.<\/jats:p>","DOI":"10.3390\/jcm11237106","type":"journal-article","created":{"date-parts":[[2022,11,30]],"date-time":"2022-11-30T07:10:27Z","timestamp":1669792227000},"page":"7106","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Myocardial Injury in Hospitalized Patients with Myasthenia Gravis"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6998-2493","authenticated-orcid":false,"given":"Hongxi","family":"Chen","sequence":"first","affiliation":[{"name":"Department of Neurology, West China Hospital, Sichuan University, Chengdu 610041, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lingyao","family":"Kong","sequence":"additional","affiliation":[{"name":"Department of Neurology, West China Hospital, Sichuan University, Chengdu 610041, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ying","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Neurology, West China Hospital, Sichuan University, Chengdu 610041, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xue","family":"Lin","sequence":"additional","affiliation":[{"name":"Department of Neurology, West China Hospital, Sichuan University, Chengdu 610041, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ziyan","family":"Shi","sequence":"additional","affiliation":[{"name":"Department of Neurology, West China Hospital, Sichuan University, Chengdu 610041, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qin","family":"Du","sequence":"additional","affiliation":[{"name":"Department of Neurology, West China Hospital, Sichuan University, Chengdu 610041, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaofei","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Neurology, West China Hospital, Sichuan University, Chengdu 610041, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yanlin","family":"Lang","sequence":"additional","affiliation":[{"name":"Department of Neurology, West China Hospital, Sichuan University, Chengdu 610041, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Linjun","family":"Cai","sequence":"additional","affiliation":[{"name":"Department of Neurology, West China Hospital, Sichuan University, Chengdu 610041, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zichao","family":"Mou","sequence":"additional","affiliation":[{"name":"Department of Neurology, West China Hospital, Sichuan University, Chengdu 610041, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wenqin","family":"Luo","sequence":"additional","affiliation":[{"name":"Department of Neurology, West China Hospital, Sichuan University, Chengdu 610041, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shuangjie","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Neurology, West China Hospital, Sichuan University, Chengdu 610041, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7637-1305","authenticated-orcid":false,"given":"Hongyu","family":"Zhou","sequence":"additional","affiliation":[{"name":"Department of Neurology, West China Hospital, Sichuan University, Chengdu 610041, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2570","DOI":"10.1056\/NEJMra1602678","article-title":"Myasthenia Gravis","volume":"375","author":"Gilhus","year":"2016","journal-title":"N.
