Prognostic value of serum bilirubin in patients with heart failure

Background Heart failure (HF) is one of the common and critical disease, and often accompanied by increased level of serum bilirubin, but the role of an indicator of bilirubin to monitor the prognosis of patients with heart failure is still unclear, so we implemented the study to systematically evaluate the predictive value of bilirubin in HF. Methods A comprehensive search and systematic review will be conducted on electronic databases such as Medline, Cochrane Library, Embase, Web of Science, Cochrane Clinical Trials Database of study on the relationship between bilirubin and prognosis of HF patients. Review Manager software (version 5.3.5) and STATA 14 software (version 14.0) will be used for data analysis and synthesis. Results The results will systematically and comprehensively reveal the evidence on the predictive value of bilirubin in HF. Conclusion The study will display the effect of bilirubin level on the prognosis of patients with heart failure, and help clinicians to pay more attention to the level of bilirubin in patients with HF, and can take certain treatment measures as earlier as possible.
