BACKGROUND: Elevated levels of neutrophil gelatinase-associated lipocalin (NGAL) have been reported in patients with cardiovascular disease (CVD), heart failure, and stroke. We assessed the relationships between serum levels of NGAL and the prevalence of CVD, and clarified the prognostic usefulness of systemic NGAL levels in hemodialysis (HD) patients. METHODS: Eighty-eight HD patients were followed up for 1 year. Logistic regression analyses were used to investigate the relationship between de novo CVD status and NGAL levels as well as other risk factors. RESULTS: During follow-up, CVD events occurred in 20 patients. Initial serum levels of NGAL and brain natriuretic peptide of HD patients with de novo CVD were significantly higher than those of HD patients without de novo CVD. Multivariate logistic regression analyses showed that initial serum levels of NGAL were independent risk factors for de novo CVD in HD patients. When patients were classified on the basis of NGAL quartiles, multiple logistic regression analyses demonstrated that the highest quartile of NGAL level showed an increased odds ratio for the prevalence of CVD. CONCLUSION: These findings suggest that NGAL levels can be used to detect the prevalence of CVD in HD patients with or without diabetes.
