ABSTRACT
Objective To evaluate the relation between cystatin C and the presence and severity of asymptomatic coronary artery disease in metabolic syndrome(MetS).Methods A total of 201 asymptomatic MetS patients with normal renal function were per-formed the coronary angiograph and the detection of serum Cystatin C level and other risk factors for atherosclerosis.Results Ser-um cystatin C level in the MetS patients with asymptomatic coronary artery disease were significantly higher than those in the pa-tients without coronary artery disease,moreover the more severe of the disease,the higher the cyctatin C,which was independently associated with other risk factors for atherosclerosis.Conclusion Serum cystatin C level can been used as the index for the presence and severity of asymptomatic coronary artery disease in Mets with normal kidney function.
