BACKGROUND Concentration of sST2 may have prognostic value in AHF. A comprehensive assessment of all available studies regarding sST2 in AHF is lacking. METHODS Three databases (MEDLINE, Cochrane Library, and Scopus) were searched. Inclusion criteria were follow-up studies, papers published in English, enrollment of patients with AHF, and availability of median hazard ratios for all-cause death and other outcome measures, when available. RESULTS Ten studies were included, with a global population of 4,835 patients and a median follow-up duration of 13.5 months. The following global hazard ratios calculated for log2(sST2) were admission sST2 and all-cause death, 2.46 (95% confidence interval [CI]: 1.80 to 3.37; p < 0.001); discharge sST2 and all-cause death, 2.06 (95% CI: 1.37 to 3.11; p < 0.001); admission sST2 and cardiovascular death, 2.29 (95% CI: 1.41 to 3.73; p < 0.001); discharge sST2 and cardiovascular death, 2.20 (95% CI: 1.48 to 3.25; p < 0.001); admission sST2 and heart failure (HF) hospitalization, 1.21 (95% CI: 0.96 to 1.52; p = 0.060); discharge sST2 and HF hospitalization, 1.54 (95% CI: 1.03 to 2.32; p = 0.007); admission sST2 and all-cause death or HF hospitalization, 1.74 (95% CI: 1.24 to 2.45; p < 0.001); and discharge sST2 and all-cause death or HF hospitalization, 1.63 (95% CI: 1.14 to 2.33; p < 0.001). CONCLUSIONS Plasma sST2 has prognostic value with respect to all-cause and cardiovascular death as well as the composite outcome of all-cause death or HF hospitalization, with both admission and discharge values having prognostic efficacy. Discharge sST2, but not admission sST2, is predictive of HF rehospitalization during follow-up. https://sonar.ch/global/documents/49677 eng info:eu-repo/semantics/altIdentifier/doi/10.1016/j.jchf.2016.12.016 info:eu-repo/semantics/altIdentifier/pmid/28189578 JACC.
