Background: Highly sensitive cardiac troponin-T (hs-cTropT) is a predictor of mortality in dialysis dependent renal failure patients. Vascular calcification is also associated with adverse outcome in CKD. Osteoprotegerin (OPG) is a mediator of the bone-vascular axis and has been associated with adverse cardiovascular outcomes.

Aims: We investigated the relationship of hs-cTrop T with OPG and other clinical and biochemical parameters in a cohort of patients with CKD stages 3 & 4.

Method: ELISA kits were used to measure hs-cTropT (Roche, UK) and OPG (Biovendor, CZ).

Results: 122 patients were studied, 95M:27F. Age 69±11 years (mean±SD). Diabetic:Non-Diabetic 28:94. Systolic BP 154±21mmHg, DBP 154±21mmHg, eGFR 32±11ml/min/1.73m2, PO4 1.08±0.20mmol/l. uPCR* 35.8 (14.9–75.2mg/mmol) (*Geometric Mean (25th–75th centile), *iPTH 79.1 (49–127ng/l),* OPG 9.41(7.4–12.1pmol/l), *hs-cTropT 0.174 (0.010–0.283μg/l).

Significant univariate correlation was found between hs-cTropT, Age, eGFR, uPCR, iPTH, OPG.

After stepwise multivariate analysis age (β=0.420, p < 0.001), loguPCR (β = 0.290, p < 0.001), eGFR (β = −0.281, p < 0.001) and logOPG (β=0.184, p=0.011) were independently associated with loghs-cTropT. Model adjusted R2=0.491. The other variables were excluded from the model.

Conclusion: In addition to the recognised cardiovascular risk factors age and eGFR, proteinuria and plasma osteoprotegerin are independently associated with hs-cTropT in CKD stages 3 & 4. This suggests involvement in the pathogenesis of cardiovascular disease in pre-dialysis CKD.
