ABSTRACT
OBJECTIVE: We initially tried to study the possible correlation between the severity of coronary artery disease (CAD) and serum neopterin levels in stable coronary artery disease patients. Also we tried to investigate the neopterin as an indicator for the extent of CAD using the Gensini score. METHODS: A total of 40 patients with stable angina pectoris who are chosen for coronary angiography were selected for the study. Before the angiography procedure, blood samples were taken for the measurement of serum neopterin levels and the results of the coronary angiography were scored according to the Gensini scoring system. RESULTS: Neopterin levels were correlated with the Gensini scores [p = 0.010, ρ = 0.401] and a correlation between the age of patient population and Gensini score was also observed in the study [p = 0.016, ρ = 0.380]. CONCLUSION: By the guidance of our results, we can confidently state that there is a correlation between serum neopterin levels and the severity and extent of CAD in stable coronary artery disease patients.
