This study aims to assess the effect of nutritional status on in-hospital mortality in patients with heart failure. Methods: We conducted a retrospective study and analysis of medical records of 1056 patients admitted to the cardiology department of the University Clinical Hospital in Wroclaw (Poland). Results: A total of 1056 individuals were included in the analysis. A total of 5.5% of patients died during an in-hospital stay. It was found that in the sample group, 25% of patients who died had a BMI (body mass index) within the normal range, 6% were underweight, 47% were overweight, and 22% were obese. Our results show that non-survivors have a significantly higher nutrition risk screening (NRS) \u22653 (21% vs. 3%; p &lt; 0.001); NYHA (New York Heart Association) grade 4 (70% vs. 24%; p &lt; 0.001). The risk of death was lower in obese patients (HR = 0.51; p = 0.028) and those with LDL (low-density lipoprotein) levels from 116 to &lt;190 mg\/dL (HR = 0.10; p = 0.009, compared to those with LDL &lt;55 mg\/dL). The risk of death was higher in those with NRS (nutritional risk score) score \u22653 (HR = 2.31; p = 0.014), HFmrEF fraction (HR = 4.69; p &lt; 0.001), and LDL levels &gt; 190 mg\/dL (HR = 3.20; p = 0.038). Conclusion: The malnutrition status correlates with an increased risk of death during hospitalisation. Higher TC (total cholesterol) level were related to a lower risk of death, which may indicate the \u201clipid paradox\u201d. Higher BMI results were related to a lower risk of death, which may indicate the \u201cobesity paradox\u201d.<\/jats:p>","DOI":"10.3390\/nu13051669","type":"journal-article","created":{"date-parts":[[2021,5,16]],"date-time":"2021-05-16T23:17:16Z","timestamp":1621207036000},"page":"1669","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":34,"title":["The Association between Nutritional Status and In-Hospital Mortality among Patients with Heart Failure\u2014A Result of the Retrospective Nutritional Status Heart Study 2 (NSHS2)"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4245-5420","authenticated-orcid":false,"given":"Micha\u0142","family":"Czapla","sequence":"first","affiliation":[{"name":"Faculty of Health Sciences, Wroclaw Medical University, 51-618 Wroclaw, Poland"},{"name":"Centre for Heart Diseases, University Hospital, 50-566 Wroclaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ra\u00fal","family":"Ju\u00e1rez-Vela","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, University of Salamanca, 37008 Salamanca, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0519-6917","authenticated-orcid":false,"given":"Katarzyna","family":"\u0141okie\u0107","sequence":"additional","affiliation":[{"name":"Department of Propaedeutic of Civilization Diseases, Medical University of Lodz, 90-251 Lodz, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6489-2525","authenticated-orcid":false,"given":"Piotr","family":"Karniej","sequence":"additional","affiliation":[{"name":"Faculty of Health Sciences, Wroclaw Medical University, 51-618 Wroclaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,5,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1016\/j.jacc.2017.04.052","article-title":"Global, Regional, and National Burden of Cardiovascular Diseases for 10 Causes, 1990 to 2015","volume":"70","author":"Roth","year":"2017","journal-title":"J.
