Associations of serum cystatin C and its change with new-onset cardiovascular disease in Chinese general population.

Abstract

BACKGROUND AND AIMS:

The relation of serum cystatin C with new-onset cardiovascular disease (CVD) remains uncertain. We aimed to evaluate the prospective associations of serum cystatin C and its change with new-onset CVD in Chinese general population.

METHODS AND RESULTS:

A total of 7064 participants free of CVD at baseline were enrolled from the China Health and Retirement Longitudinal Study. The change in serum cystatin C was calculated as cystatin C concentration at 2015 wave minus that at baseline (2011 wave). The primary outcome was new-onset CVD, defined as self-reported physician-diagnosed heart disease, stroke, or both during follow-up. The secondary outcomes were new-onset heart disease, and new-onset stroke. During a median follow-up duration of 7.0 years, a total of 1116 (15.8%) subjects developed new-onset CVD. Overall, after the adjustments for eGFR and other important covariates, there was a positive association between serum cystatin C and new-onset CVD (per SD mg/L increment; adjusted HR, 1.13; 95%CI: 1.08,1.18). When cystatin C was assessed as quintiles, the adjusted HRs for participants in the second, third, fourth and fifth quintiles were 1.15 (95%CI: 0.93, 1.41), 1.37 (95%CI: 1.11, 1.68), 1.47 (95%CI: 1.19, 1.81), and 2.03 (95%CI: 1.60, 2.56), respectively, compared with those in quintile 1 (P for trend<0.001). Furthermore, there was a positive association between the increase in cystatin C concentration and the subsequent new-onset CVD (per SD mg/L increment; adjusted HR, 1.14; 95%CI: 1.02,1.27).

CONCLUSION:

Both serum cystatin C and its increase were positively associated with new-onset CVD among Chinese general population.
