Heart failure (HF) is a clinical disorder and zinc is an important cofactor in regulating oxidative status. Objective: The present study aimed to determine the mean concentration of serum zinc in patients with HF. Methods: PubMed, Embase, Scopus and Web of Science were searched to find relevant cross-sectional studies up to 1st January 2020. A random-effects model was used to pool the effect size (ES) and 95 % confidence intervals (CI). Meta-regression analysis was performed to find the sources of statistical heterogeneity among the studies. Results: Our meta-analysis of 1358 HF patients indicated that their mean serum zinc concentration was 66.24 μg/dl (95 % CI: 59.16, 73.33). In sub-analysis, the mean concentration was 75.04 μg/dl and 52.90 μg/dl in patients < 65 years and > 65 years old, respectively. Subgroup analysis by geographical region showed that mean serum zinc was 70.70 μg/dl, 69.08 μg/dl and 60.91 μg/dl in HF patients from Europe, America and Asia, respectively. Meta-regression analysis indicated a reduction of 1.42 μg/dl in serum zinc for each year aged. Conclusion: In summary, our meta-analysis indicate that serum zinc concentrations have a narrow range in HF patients’ worldwide, that declines with age and varies with geographical region.
