Summary

This study examined the predictive value of plasma cystatin C, creatinine and estimated glomerular filtration rate (eGFR) as risk factors for cardiovascular disease in Chinese. Plasma cystatin C and creatinine were measured in 466 coronary heart disease (CHD) patients recruited from 4 hospitals and 349 healthy controls from local communities in Wuhan, China. Cockroft-Gault formula was used to estimate the glomerular filtration rate (GFR) after adjusting for body surface area. With each measure, the study population was divided into quintiles. The results showed that the patients had significantly higher levels of plasma cystatin C, creatinine, and lower level of eGFR than controls. Lower eGFR was associated with a higher risk of cardiovascular events. As compared with the first (highest) quintile, the hazard ratios (and 95% CIs) after multivariate adjustment for CHD were as follows: third quintile, 2.98 (1.54–5.78); fourth quintile, 3.34 (1.58–7.09); fifth quintile, 4.37(1.84–10.35). With higher cystatin C quintiles (≥1.00 mg/L and ≥1.17 mg/L), the hazard ratios for CHD were 2.16 (1.23–3.81) and 2.34 (1.25–4.38), similar to those of creatinine 2.21 (1.21–4.03) and 2.03 (1.07–3.84). However, it was plasma cystatin C not eGFR or creatinine had stronger association with ischemic stroke. The highest quintile had the hazard ratio of 4.51 (1.45–14.08) after multivariate adjustment. It was concluded that plasma cystatin C, associated with renal function, is not an independent risk factor for cardiovascular disease. eGFR is a better risk predictor for CHD than plasma cystatin C and creatinine. But for ischemic stroke, plasma cystatin C is a better risk factor than creatinine and estimated GFR.
