We aimed to analyse deformation parameters in endurance athletes relative to patients with DCM using cardiac magnetic resonance feature tracking (CMR-FT). The study included males of a similar age: 22 ultramarathon runners, 22 patients with DCM and 21 sedentary healthy controls (41 \u00b1 9 years). The analysed parameters were peak LV global longitudinal, circumferential and radial strains (GLS, GCS and GRS, respectively); peak LV torsion; peak RV GLS. The peak LV GLS was similar in controls and athletes, but lower in DCM (p &lt; 0.0001). Peak LV GCS and GRS decreased from controls to DCM (both p &lt; 0.0001). The best value for differentiation between DCM and other groups was found for the LV ejection fraction (area under the curve (AUC) = 0.990, p = 0.0001, with 90.9% sensitivity and 100% specificity for \u226453%) and the peak LV GRS diastolic rate (AUC = 0.987, p = 0.0001, with 100% sensitivity and 88.4% specificity for &gt;\u22121.27 s\u22121). The peak LV GRS diastolic rate was the only independent predictor of DCM (p = 0.003). Distinctive deformation patterns that were typical for each of the analysed groups existed and can help to differentiate between athlete\u2019s heart, a nonathletic heart and a dilated cardiomyopathy.<\/jats:p>","DOI":"10.3390\/diagnostics11020374","type":"journal-article","created":{"date-parts":[[2021,2,22]],"date-time":"2021-02-22T14:23:27Z","timestamp":1614003807000},"page":"374","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["Deformation Parameters of the Heart in Endurance Athletes and in Patients with Dilated Cardiomyopathy\u2014A Cardiac Magnetic Resonance Study"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9586-0163","authenticated-orcid":false,"given":"\u0141ukasz A.","family":"Ma\u0142ek","sequence":"first","affiliation":[{"name":"Department of Epidemiology Cardiovascular Disease Prevention and Health Promotion, National Institute of Cardiology, 04-635 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"\u0141ukasz","family":"Mazurkiewicz","sequence":"additional","affiliation":[{"name":"Department of Cardiomyopathy, National Institute of Cardiology, 04-628 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Miko\u0142aj","family":"Marsza\u0142ek","sequence":"additional","affiliation":[{"name":"Medical University of Warsaw, 02-091 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marzena","family":"Barczuk-Fal\u0119cka","sequence":"additional","affiliation":[{"name":"Department of Pediatric Radiology, Medical University of Warsaw, 02-091 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jenny E.","family":"Simon","sequence":"additional","affiliation":[{"name":"Medical University of Warsaw, 02-091 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jacek","family":"Grzybowski","sequence":"additional","affiliation":[{"name":"Department of Cardiomyopathy, National Institute of Cardiology, 04-628 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Barbara","family":"Mi\u0142osz-Wieczorek","sequence":"additional","affiliation":[{"name":"Department of Radiology, National Institute of Cardiology, 04-628 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7826-4458","authenticated-orcid":false,"given":"Marek","family":"Postu\u0142a","sequence":"additional","affiliation":[{"name":"Department of Experimental and Clinical Pharmacology Centre for Preclinical Research and Technology (CEPT), Medical University of Warsaw, 02-097 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Magdalena","family":"Marczak","sequence":"additional","affiliation":[{"name":"Department of Radiology, National Institute of Cardiology, 04-628 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,2,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"23","DOI":"10.7326\/0003-4819-130-1-199901050-00005","article-title":"Physiologic Left Ventricular Cavity Dilatation in Elite Athletes","volume":"130","author":"Pelliccia","year":"1999","journal-title":"Ann.
