    Abstract Background Serum cardiac troponin (cTn) elevation is a well-established phenomenon in sepsis. However, the clinical signifcance of this phenomenon with high-sensitivity (hs) assays and the current sepsis defnition needs to be settled. Research Question What is the association between early serum cTn levels measured by hs-assays and the risk of short-term mortality in septic patients? Study Design and Methods We conducted a systematic review using a comprehensive PubMed, Scopus, and Embase search. Studies were eligible if they reported association data on early hs-cTn and mortality in an adult sample with sepsis that met the Sepsis-3 defnition. For the synthesis of the efect of hs-cTn on mortality, we applied random efect models on the pooled unadjusted and adjusted odds ratio (OR and aOR, respectively) of elevated vs. normal hs-cTn serum values, and on the crude standardized mean diference (SMD) of hs-cTn between survivors and non-survivors. Results In total, 6242 patients from 17 studies were included, with short-term mortality rates ranging from 16.9% to 53.8%. Using a crude analysis, non-survivor patients showed higher hs-cTn than survivors (SMD of 0.87, 95%CI: 0.41–1.33). Elevated hs-cTn was associated with increased mortality (OR=1.78, 95% CI: 1.41–2.25). However, this prognostic efect was absent in studies that adjusted for diferent confounders (aOR=1.06, 95% CI: 0.99–1.14). Discussion and Conclusions Non-survivors of sepsis exhibited signifcantly elevated hs-cTn levels. While elevated hs-cTn levels are associated with an increased risk of mortality, they are not independently associated with this outcome in sepsis

    <jats:sec id="sec001"> <jats:title>Background</jats:title> <jats:p>Sepsis is a common admission diagnosis in the intensive care unit (ICU). The Sepsis-3 consensus associates sepsis diagnosis with acute organ dysfunction. In these patients troponin elevation is a well-established phenomenon, but its clinical significance is not settled, as no systematic review has addressed the prognostic significance of the increasingly prevalent high-sensitivity troponin assays in acute organ dysfunction setting.</jats:p> <jats:p>This study aims to clarify the association between early serum troponin levels in high-sensitivity assays with short-term mortality risk in septic patients with acute organ dysfunction.</jats:p> </jats:sec> <jats:sec id="sec002"> <jats:title>Methods</jats:title> <jats:p>We will systematically search PubMed, Scopus and Embase for original articles; additionally, a manual search will be carried out through relevant literature. Generally, studies will be deemed eligible for inclusion if they evaluate the association between high-sensitivity troponin in the first 24 hours of admission and ICU, 30-days, or In-hospital mortality; in patients with septic shock or sepsis related to acute organ dysfunction. Two reviewers will independently select studies and extract the data. A meta-analysis for mortality outcome will be performed for comparative data regarding two effect measures: Odd ratios and Standardized Mean differences.</jats:p> </jats:sec> <jats:sec id="sec003"> <jats:title>Discussion</jats:title> <jats:p>This study will provide further evidence about the role of high-sensitivity troponin assays in predicting mortality in septic patients; potentially helping to guide further research and yielding valuable information for patient assessment.</jats:p> <jats:p>Conclusion about the certainty of evidence will be presented in a ´Summary of findings´ table.</jats:p> </jats:sec> <jats:sec id="sec004"> <jats:title>Trial registration</jats:title> <jats:p>PROSPERO registration:</jats:p> <jats:p>(<jats:ext-link xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="uri" xlink:href="https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42024468883" xlink:type="simple">CRD42024468883</jats:ext-link>).</jats:p> </jats:sec>
