The purpose of this study was to evaluate the potential relationship between the myocardial mechanics of different chambers of the heart and the presence of MF and to determine the accuracy of the whole-heart myocardial strain parameters to predict MF in patients with NIDCM. Methods: We studied 101 patients (64% male; 50 \u00b1 11 years) with a first-time diagnosis of NIDCM who were referred for a clinical cardiovascular magnetic resonance (CMR) and speckle tracking 2D echocardiography examination. We analyzed MF by late gadolinium enhancement (LGE), and the whole-heart myocardial mechanics were assessed by speckle tracking. The presence of MF was related to worse strain parameters in both ventricles and atria. The strongest correlations were found between MF and left ventricle (LV) global longitudinal strain (GLS) (r = \u22120.586, p &lt; 0.001), global circumferential strain (GCS) (r = \u22120.609, p &lt; 0.001), LV ejection fraction (LVEF) (r = 0.662, p &lt; 0.001), and left atrial strain during the reservoir phase (LASr) (r = 0.588, p &lt; 0.001). However, the binary logistic regression analysis revealed that only LV GLS, GCS, and LASr were independently associated with the presence of MF (area under the curves of 0.84, 0.85, and 0.64, respectively). None of the echocardiographic parameters correlated with fibrosis localization. Conclusions: In NIDCM patients, MF is correlated with reduced mechanical parameters in both ventricles and atria. LV GLS, LASr, and LV GCS are the most accurate 2D echocardiography predictive factors for the presence of MF.<\/jats:p>","DOI":"10.3390\/jcm11226607","type":"journal-article","created":{"date-parts":[[2022,11,8]],"date-time":"2022-11-08T10:53:52Z","timestamp":1667904832000},"page":"6607","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Association of Whole-Heart Myocardial Mechanics by Transthoracic Echocardiography with Presence of Late Gadolinium Enhancement by CMR in Non-Ischemic Dilated Cardiomyopathy"],"prefix":"10.3390","volume":"11","author":[{"given":"Karolina","family":"M\u0117linyt\u0117-Ankudavi\u010d\u0117","sequence":"first","affiliation":[{"name":"Department of Cardiology, Medical Academy, Lithuanian University of Health Sciences, LT-50161 Kaunas, Lithuania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paulius","family":"Bu\u010dius","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Medical Academy, Lithuanian University of Health Sciences, LT-50161 Kaunas, Lithuania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vaida","family":"Mizarien\u0117","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Medical Academy, Lithuanian University of Health Sciences, LT-50161 Kaunas, Lithuania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tomas","family":"Lapinskas","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Medical Academy, Lithuanian University of Health Sciences, LT-50161 Kaunas, Lithuania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gintar\u0117","family":"\u0160akalyt\u0117","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Medical Academy, Lithuanian University of Health Sciences, LT-50161 Kaunas, Lithuania"},{"name":"Institute of Cardiology, Lithuanian University of Health Sciences, LT-50162 Kaunas, Lithuania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jurgita","family":"Plisien\u0117","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Medical Academy, Lithuanian University of Health Sciences, LT-50161 Kaunas, Lithuania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Renaldas","family":"Jurkevi\u010dius","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Medical Academy, Lithuanian University of Health Sciences, LT-50161 Kaunas, Lithuania"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"353","DOI":"10.1016\/j.tcm.2019.09.003","article-title":"Current understanding of fibrosis in genetic cardiomyopathies","volume":"30","author":"Eijgenraam","year":"2020","journal-title":"Trends Cardiovasc.
