In DCM, the mortality risk is high and reaches approximately 20% in 5 years. A patient\u2019s prognosis should be established for appropriate HF management. However, so far, no validated tools have been available for the DCM population. Methods: The study population consisted of 735 DCM patients: 406 from the derivation cohort (previously described) and 329 from the validation cohort (from 2009 to 2020, with outcome data after a mean of 42 months). For each DCM patient, the individual mortality risk was calculated based on the Krakow DCM Risk Score. Results: During follow-up, 49 (15%) patients of the validation cohort died. They had shown significantly higher calculated 1-to-5-year mortality risks. The Krakow DCM Risk Score yielded good discrimination in terms of overall mortality risk, with an AUC of 0.704\u20130.765. Based on a 2-year mortality risk, patients were divided into non-high (\u22646%) and high (&gt;6%) mortality risk groups. The observed mortality rates were 8.3% (n = 44) vs. 42.6% (n = 75), respectively (HR 3.37; 95%CI 1.88\u20136.05; p &lt; 0.0001). Conclusions: The Krakow DCM Risk Score was found to have good predictive accuracy. The 2-year mortality risk &gt; 6% has good discrimination for the identification of high-risk patients and can be applied in everyday practice.<\/jats:p>","DOI":"10.3390\/jpm12020236","type":"journal-article","created":{"date-parts":[[2022,2,8]],"date-time":"2022-02-08T23:37:48Z","timestamp":1644363468000},"page":"236","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Clinical Utility and Validation of the Krakow DCM Risk Score\u2014A Prognostic Model Dedicated to Dilated Cardiomyopathy"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7921-5447","authenticated-orcid":false,"given":"Ewa","family":"Dziewi\u0119cka","sequence":"first","affiliation":[{"name":"Department of Cardiac and Vascular Diseases, Jagiellonian University Collegium Medicum, John Paul II Hospital, 31-202 Krakow, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0176-7882","authenticated-orcid":false,"given":"Mateusz","family":"Winiarczyk","sequence":"additional","affiliation":[{"name":"Students\u2019 Scientific Group at Department of Cardiac and Vascular Diseases, Jagiellonian University Collegium Medicum, John Paul II Hospital, 31-008 Krakow, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sylwia","family":"Wi\u015bniowska-\u015amia\u0142ek","sequence":"additional","affiliation":[{"name":"Department of Cardiac and Vascular Diseases, Jagiellonian University Collegium Medicum, John Paul II Hospital, 31-202 Krakow, Poland"},{"name":"Department of Cardiovascular Surgery and Transplantology, Jagiellonian University Collegium Medicum, John Paul II Hospital, 31-008 Krakow, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aleksandra","family":"Karabinowska-Ma\u0142ocha","sequence":"additional","affiliation":[{"name":"Department of Cardiac and Vascular Diseases, Jagiellonian University Collegium Medicum, John Paul II Hospital, 31-202 Krakow, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0585-2539","authenticated-orcid":false,"given":"Matylda","family":"Gliniak","sequence":"additional","affiliation":[{"name":"Students\u2019 Scientific Group at Department of Cardiac and Vascular Diseases, Jagiellonian University Collegium Medicum, John Paul II Hospital, 31-008 Krakow, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jan","family":"Robak","sequence":"additional","affiliation":[{"name":"Students\u2019 Scientific Group at Department of Cardiac and Vascular Diseases, Jagiellonian University Collegium Medicum, John Paul II Hospital, 31-008 Krakow, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1094-7922","authenticated-orcid":false,"given":"Monika","family":"Kaciczak","sequence":"additional","affiliation":[{"name":"Students\u2019 Scientific Group at Department of Cardiac and Vascular Diseases, Jagiellonian University Collegium Medicum, John Paul II Hospital, 31-008 Krakow, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4529-2687","authenticated-orcid":false,"given":"Przemys\u0142aw","family":"Leszek","sequence":"additional","affiliation":[{"name":"Department of Heart Failure and Transplantation, The Cardinal Stefan Wyszy\u0144ski Institute of Cardiology, 04-628 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ma\u0142gorzata","family":"Celi\u0144ska-Spodar","sequence":"additional","affiliation":[{"name":"Department of Anaesthesiology and Intensive Care, The National Institute of Cardiology, 04-628 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marcin","family":"Dziewi\u0119cki","sequence":"additional","affiliation":[{"name":"College of Economics and Computer Science (WSEI), 31-150 Krakow, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6979-3411","authenticated-orcid":false,"given":"Pawe\u0142","family":"Rubi\u015b","sequence":"additional","affiliation":[{"name":"Department of Cardiac and Vascular Diseases, Jagiellonian University Collegium Medicum, John Paul II Hospital, 31-202 Krakow, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,2,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"270","DOI":"10.1093\/eurheartj\/ehm342","article-title":"Classification of the cardiomyopathies: A position statement from the european society of cardiology working group on myocardial and pericardial diseases","volume":"29","author":"Elliott","year":"2008","journal-title":"Eur.
