A significant increase in all-cause mortality was observed across Hb quartiles at 1 month (Ptrend = 0.035) and 1 year (Ptrend < 0.01). Q1 patients had 1.64 times higher mortality at 1 month (1.09-2.47, p = 0.02) and 2.53 times higher mortality at 1 year (1.84-3.49, p < 0.01) compared to Q4. The negative effect of low Hb level was confirmed in multivariate Cox regression adjusted for baseline characteristics, and was stronger in men, non-ischemic CS, patients without CKD and patients aged < 67 years.</p><p><strong>Conclusion: </strong>Anemia is a common condition frequently intertwined with CS worsening both short- and long-term mortality. Further randomized studies are warranted to understand its mechanisms and adapt the transfusion strategy.</p>","PeriodicalId":16123,"journal":{"name":"Journal of Intensive Care","volume":"13 1","pages":"36"},"PeriodicalIF":3.8,"publicationDate":"2025-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12183877/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144475642","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
