Background:
It remains unknown whether inflammation may predict a worse prognosis with valvular calcification (VC) in end-stage renal disease (ESRD) patients.
Method:
We prospectively performed echocardiography in 231 ESRD patients receiving chronic peritoneal dialysis treatment to detect VC and then followed them for 3 years or until death.
Results:
Patients with VC had higher C-reactive protein (CRP; p = 0.001), higher interleukin-6 (IL-6; p = 0.002) and lower fetuin-A (p = 0.004). Stratifying patients into 4 groups on the basis of VC, CRP, IL-6 and fetuin-A, respectively, those with VC and CRP in the upper tertile had 3.68-fold (95% confidence intervals [CI], 1.72-7.88; p = 0.001) and 3.13-fold (95% CI, 1.57-6.24; p = 0.001) respective increases in the adjusted risk of mortality and major adverse cardiovascular event (MACE) than those with no VC and CRP in the lower/middle tertiles. The adjusted hazard ratios (HR) in relation to mortality and MACE were 3.56 (95% CI, 1.53-8.26; p = 0.003) and 2.51 (95% CI, 1.24-5.11; p = 0.011), respectively, for patients with VC and IL-6 in the upper tertile compared to those with no VC and IL-6 in the lower/middle tertiles. The adjusted HR in relation to mortality and MACE were 3.56 (95% CI, 1.53-8.26; p = 0.003) and 2.51 (95% CI, 1.24-5.11; p = 0.011), respectively, for patients with VC and fetuin-A in the lower tertile compared to those with no VC and fetuin-A in the middle/upper tertiles.
Conclusions:
Increased circulating inflammatory proteins predict a worse prognosis of VC in chronic peritoneal dialysis patients.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
