Summary: | Background
Chronic kidney disease (CKD) is associated with an increased cardiovascular disease (CVD) mortality risk. Elevation of cardiac biomarkers in patients with renal dysfunction is ambiguous in the diagnosis of CVD. The purpose of this study was to investigate the associations between estimated glomerular filtration rate (eGFR) and cardiac biomarkers, and the influence of renal dysfunction on the cardiac biomarkers.
Methods
We examined the cross‐sectional associations of eGFR with cardiac troponin I (cTnI), creatine kinase (CK), CK‐MB, lactic dehydrogenase (LDH), hydroxybutyrate dehydrogenase (HBDH), and brain natriuretic peptide (BNP) in 812 adults and 215 child. Spearman correlation and logistic regression analysis were performed to evaluate the associations.
Results
For adults, lower eGFR CKD‐EPI had significantly higher cTnI, CK‐MB, LDH, HBDH, and BNP. There were negative correlations between eGFRCKD‐EPI and cTnI, CK‐MB, LDH, HBDH, and BNP. After adjustment for potential confounders, as compared with eGFRCKD‐EPI ≥ 90 mL/min/1.73 m2, eGFRCKD‐EPI < 60 mL/min/1.73 m2 remained associated with a 2.83 (1.08‐7.41) [ratio (95% CI)] times higher cTnI and a 6.50 (2.32‐18.22) [ratio (95% CI)] times higher HBDH. For child, lower eGFRSchwartz had significant higher CK and CK‐MB. There were negative correlations between eGFRSchwartz and CK, and eGFRSchwartz and CK‐MB. After adjustment for potential confounders, as compared with eGFRSchwartz ≥ 90 mL/min/1.73 m2, eGFRSchwartz < 90 mL/min/1.73 m2 revealed no significant higher CVD biomarkers.
Conclusion
Reduced eGFR is associated with elevated cTnI and HBDH among adults without clinically evident CVD, but not child. |
