Abstract
PURPOSE: Cardiac complication is a major cause of death in hemodialysis patients. The aim of the study was to determine the relationship between plasma catestatin level and cardiac death in those people. METHODS: A total of 330 maintenance hemodialysis patients were included. Blood samples were collected. Plasma catestatin level was detected by enzyme-linked immunosorbent assay. Fluid status of each patient was expressed by overhydration to total body weight ratio and daily diuresis. Each patient was followed-up for 36 months, unless some of them died in the follow-up period. RESULTS: In the follow-up period, only one hemodialysis patient was lost, 29 patients were died of cardiovascular diseases, 28 patients were died of other diseases and remaining 272 patients survived. Logistic multivariate regression analysis revealed that patients with plasma catestatin level ≥1.9 ng/ml were associated with increased cardiac death risk (RR 6.13, 95% CI 2.54, 18.45), and survival analysis also showed that cardiac death rate in patients with plasma catestatin level ≥1.9 ng/ml was elevated than that in patients with plasma catestatin level <1.9 ng/ml (P < 0.001). In addition, overhydration to total body weight ratio and daily diuresis both had significant linear correlations with plasma catestatin level (r = 0.502, P < 0.001 and r = -0.338, P < 0.001). CONCLUSION: Circulating catestatin concentration might be an independent cardiac prognostic indicator in hemodialysis patients. Fluid status might be involved in the prognostic forecasting process.
