Insights
Elevated serum uric acid (SUA) levels in acute heart failure (AHF) patients independently predict higher risks of all-cause mortality and death or readmission. SUA measurement can improve risk stratification for adverse outcomes in AHF.
Area of Science:
- Cardiology
- Clinical Research
- Biomarkers
Background:
- Conflicting data exists on the prognostic value of serum uric acid (SUA) in acute heart failure (AHF).
- This meta-analysis addresses the prognostic significance of SUA levels in AHF patients.
Purpose of the Study:
- To determine the prognostic significance of serum uric acid (SUA) levels in patients with acute heart failure (AHF).
Main Methods:
- A comprehensive literature search was conducted in PubMed and Embase databases up to April 6, 2018.
- Included were observational studies and post hoc analyses evaluating SUA's prognostic value in AHF.
- Outcomes assessed were all-cause mortality and the composite of death or readmission.
Main Results:
- Ten studies with 12,854 AHF patients were analyzed.
- Highest SUA levels correlated with increased risk of all-cause mortality (RR 1.43) and death/readmission (RR 1.68).
- Each 1 mg/ml SUA increase was associated with an 11-12% higher risk of adverse outcomes.
Conclusions:
- Elevated SUA levels independently predict mortality and readmission in AHF patients.
- SUA measurement may enhance risk stratification for adverse outcomes in AHF.
Background:
Conflicting results have been reported on the prognostic significance of serum uric acid (SUA) in patients with acute heart failure (AHF). This meta-analysis aimed to determine the prognostic significance of SUA level in patients with AHF.
Methods:
We made a comprehensive literature search in Pubmed and Embase databases from inception to April 6, 2018. All available observational studies or post hoc analysis of randomized controlled trial that evaluated the prognostic value of SUA level in patients with AHF were eligible. Outcome of interests were all-cause mortality and the combined endpoint of death or readmission. Prognostic values of SUA level were summarized as higher vs lower SUA category or per 1 mg/ml SUA rise.
Results:
Ten studies involving 12,854 AHF patients were identified and analyzed. AHF patients with the highest SUA level had an increased risk of all-cause mortality (risk ratio [RR] 1.43; 95% confidence intervals [CI] 1.31-1.56) and combined endpoint of death or readmission (RR 1.68; 95% CI 1.33-2.13) after adjusting potential variables. In addition, per 1 mg/ml SUA rise significantly increased by 11% and 12% higher risk all-cause mortality and combined endpoint of death or readmission, respectively. A leave out 1 study sensitivity analysis confirmed the reliability of the pooling effect sizes.
Conclusion:
This meta-analysis indicates that elevated SUA level independently predicts all-cause mortality and the combined endpoint of death or readmission in AHF patients. Measurement of SUA level may improve risk stratification of adverse outcomes in these patients.
