Evaluation of relationship between serum neopterin,cystatin c and coronary heart disease

Abstract

Aim It has been reported that neopterin, a key molecule for immun response organization, is released from active macrophages of atheromatous plaque and useful for cardiovascular risk stratification. The aim of this study was to investigate serum cystatin C and neopterin levels in patients with coronary artery disease and examine the relationship between these markers and cardiovascular risk factors.Methods Coronary artery disease group and control group consisted of 75 subjects (61 males, 14 females, mean age 60.5±10) and 50 subjects (25 males, 25 females, mean age 56.9±10), respectively.Results Serum neopterin concentrations were higher in coronary artery disease group compared to control group. A negative correlation was established between neopterin and high density lipoprotein cholesterol. Also, there was a positive correlation between Gensini score and cystatin C and neopterin.Conclusion Serum cystatin C and neopterin concentrations might be useful markers for determining the coronary artery disease’s severity. According to this study, neopterin seems to be a stronger indicator of cardiovascular diseases compared to cystatin C. The positive correlation between Gensini score and the biochemical markers offers us a potential use of these markers in evaluating the disease’s severity.
