Studies on the role of MW in dilated cardiomyopathy (DCM) are still limited. Therefore, the aim of this study was to evaluate the potential value of MW for predicting adverse outcomes in patients with DCM. 116 consecutive patients with DCM who underwent heart catheterization were retrospectively recruited from June 2009 to July 2014. 34 patients (30%) met the composite endpoints for major adverse cardiac events (MACE) of cardiac transplantation, need for implantable cardioverter-defibrillator (ICD) therapy, heart failure hospitalization and all-cause mortality. Patients with DCM were followed up for a mean of 5.1 years (IQR: 2.2\u20139.1 years). Global work index (GWI) and global constructive work (GCW) were not only independent predictors but also provided incremental predictive values (Integrated discrimination improvement [IDI]\u2009&gt;\u20090) of MACE in multivariate Cox models. Furthermore, Patients with GWI\u2009&lt;\u2009788\u00a0mm Hg% (HR 5.46, 95%CI 1.66\u201317.92, <jats:italic>p<\/jats:italic>\u2009=\u20090.005) and GCW\u2009&lt;\u20091,238\u00a0mm Hg% (HR 4.46, 95%CI 1.53\u201312.98, <jats:italic>p<\/jats:italic>\u2009=\u20090.006) had higher risks of MACE. GWI and GCW assessed by strain imaging echocardiography may have an additional value beyond LV-EF and GLS for predicting adverse outcomes in DCM.<\/jats:p>","DOI":"10.1007\/s10554-024-03144-5","type":"journal-article","created":{"date-parts":[[2024,5,23]],"date-time":"2024-05-23T09:02:12Z","timestamp":1716454932000},"page":"1575-1584","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Prognostic relevance of global work index and global constructive work in patients with non-ischemic dilated cardiomyopathy"],"prefix":"10.1007","volume":"40","author":[{"given":"Peng","family":"Chen","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthias","family":"Aurich","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sebastian","family":"Greiner","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gabriele","family":"Maliandi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthias","family":"M\u00fcller-Hennessen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Evangelos","family":"Giannitsis","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Benjamin","family":"Meder","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Norbert","family":"Frey","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sven","family":"Pleger","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Derliz","family":"Mereles","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2024,5,23]]},"reference":[{"key":"3144_CR1","doi-asserted-by":"publisher","first-page":"400","DOI":"10.1016\/S0140-6736(16)31713-5","volume":"390","author":"RG Weintraub","year":"2017","unstructured":"Weintraub RG, Semsarian C, Macdonald P (2017) Dilated cardiomyopathy.
