Abstract:

Objective

To investigate the relationship between major adverse cardiovascular events (MACE) and serum levels of heat shock protein 70 (HSP-70) and clusterin in patients undergoing maintenance hemodialysis.

Methods

A total of 183 end-stage renal disease patients undergoing maintenance hemodialysis were selected as the study subjects whose baseline data were recorded. And the patients were divided into the MACE group (57 cases) and the non-MACE group (126 cases) based on MACE during the one-year follow-up. Enzyme-linked immunosorbent assay (ELISA) was applied to measure the serum levels of HSP-70 and clusterin. Receiver operating characteristic (ROC) curve was applied to analyze the value of serum HSP-70 and clusterin in evaluating occurrence of MACE in the patients. Multivariate logistic regression method was used to analyze the affecting factors for occurrence of MACE in the patients.

Results

The serum levels of HSP-70, clusterin, triglyceride, and parathyroid hormone of the MACE group were higher than those of the non-MACE group (t=7.763, 8.550, 4.156, 4.908, respectively), while LVEF was lower than that of the non-MACE group (t=10.931) (P<0.05). The AUC of serum HSP-70, clusterin, and HSP-70 plus clusterin in evaluating MACE in the patients was 0.757, 0.859, and 0.903, respectively. HSP-70 and clusterin were independent affecting factors for MACE occurrence in the patients (OR=2.947, 3.074, respectively; 95%CI: 1.549-5.605, 1.691-5.589, respectively; P<0.05).

Conclusion

In maintenance hemodialysis patients complicated with MACE, elevated levels of serum HSP-70 and clusterin were influencing factors for the occurrence of MACE. When evaluating the risk of MACE occurrence in clinical practice, serum HSP-70 and clusterin might serve as reference indicators.
