Abstract/OtherAbstract:
BACKGROUND: Left ventricular ejection fraction (LVEF) is the strongest predictor of survival in patients with chronic stable angina (CSA). Inflammation plays a key role in the pathogenesis of atherosclerosis and an enhanced inflammatory status has a negative impact on patient outcome. It is not known whether a relationship exists between inflammation and LV function in patients with CSA. We therefore sought to investigate whether C reactive protein (CRP) and neopterin correlate with LV dysfunction in patients with CSA. METHODS: We assessed 181 patients with CSA who underwent diagnostic coronary angiography in our institution. High-sensitivity CRP and neopterin serum concentrations were measured immediately before angiography. RESULTS: Baseline neopterin levels - but not CRP - showed a significant inverse correlation with LVEF (r=-0.222; p=0.003 and r=-0.097; p=0.194, respectively). After adjustment for relevant confounders which included, among others, the extent and severity of coronary disease, neopterin was found to be independently associated with LVEF (B -2.36, CI 95% -4.560 to -0.176, p=0.034). Moreover, high neopterin levels were an independent predictor of LV dysfunction (LVEF <45%) (OR, 8.52, CI 95% 1.10-65.64; p=0.040). Receiver operating characteristic analysis for neopterin showed an area under the curve of 0.736 (CI 95% 0.59-0.87, p<0.009) for prediction of LV dysfunction. CONCLUSION: Increased serum neopterin concentrations inversely correlate with LVEF values and high neopterin levels are a predictor of LV dysfunction in patients with CSA, irrespective of the extent and severity of coronary artery disease. Neopterin may thus be clinically useful for patient risk stratification.
