We determine LV global longitudinal strain (GLS) between athletes with a positive COVID-19 test (PCAt) and healthy control athletes (CON) and relate it to symptoms during COVID-19. GLS is determined in four-, two-, and three-chamber views and assessed offline by a blinded investigator in 88 PCAt (35% women) (training at least three times per week\/&gt;20 MET) and 52 CONs from the national or state squad (38% women) at a median of two months after COVID-19. The results show that the GLS is significantly lower (GLS \u221218.53 \u00b1 1.94% vs. \u221219.94 \u00b1 1.42%, p &lt; 0.001) and diastolic function significantly reduces (E\/A 1.54 \u00b1 0.52 vs. 1.66 \u00b1 0.43, p = 0.020; E\/E\u2019l 5.74 \u00b1 1.74 vs. 5.22 \u00b1 1.36, p = 0.024) in PCAt. There is no association between GLS and symptoms like resting or exertional dyspnea, palpitations, chest pain or increased resting heart rate. However, there is a trend toward a lower GLS in PCAt with subjectively perceived performance limitation (p = 0.054). A significantly lower GLS and diastolic function in PCAt compared with healthy peers may indicate mild myocardial dysfunction after COVID-19. However, the changes are within the normal range, so that clinical relevance is questionable. Further studies on the effect of lower GLS on performance parameters are necessary.<\/jats:p>","DOI":"10.3390\/jcdd10050189","type":"journal-article","created":{"date-parts":[[2023,4,24]],"date-time":"2023-04-24T02:06:11Z","timestamp":1682301971000},"page":"189","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Left Ventricular Global Longitudinal Strain as a Parameter of Mild Myocardial Dysfunction in Athletes after COVID-19"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7467-2614","authenticated-orcid":false,"given":"Jana","family":"Schellenberg","sequence":"first","affiliation":[{"name":"Division of Sports and Rehabilitation Medicine, University Ulm Hospital, 89075 Ulm, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Magdalena","family":"Ahathaller","sequence":"additional","affiliation":[{"name":"Division of Sports and Rehabilitation Medicine, University Ulm Hospital, 89075 Ulm, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4777-7066","authenticated-orcid":false,"given":"Lynn","family":"Matits","sequence":"additional","affiliation":[{"name":"Division of Sports and Rehabilitation Medicine, University Ulm Hospital, 89075 Ulm, Germany"},{"name":"Clinical & Biological Psychology, Institute of Psychology and Education, Ulm University, 89075 Ulm, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2986-1448","authenticated-orcid":false,"given":"Johannes","family":"Kirsten","sequence":"additional","affiliation":[{"name":"Division of Sports and Rehabilitation Medicine, University Ulm Hospital, 89075 Ulm, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Johannes","family":"Kersten","sequence":"additional","affiliation":[{"name":"Division of Sports and Rehabilitation Medicine, University Ulm Hospital, 89075 Ulm, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8901-9450","authenticated-orcid":false,"given":"Juergen Michael","family":"Steinacker","sequence":"additional","affiliation":[{"name":"Division of Sports and Rehabilitation Medicine, University Ulm Hospital, 89075 Ulm, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,4,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1443","DOI":"10.1161\/CIRCRESAHA.120.317055","article-title":"COVID-19 and the Heart","volume":"126","author":"Akhmerov","year":"2020","journal-title":"Circ.
