Abstract

Aim: The aim of this study was to establish the degree of aortic stiffness and levels of neutrophil gelatinase-associated lipocalin (NGAL) in patients with stable ischemic heart disease. Materials and Methods: Patients who were found to have stable, noncritical lesions on coronary angiography were included in the study [noncritical coronary artery disease (CAD)]. The control group consisted of those patients who had similar risk profiles and metabolic parameters without atherosclerosis on angiography. Results: A total of 101 patients were included in the study of which 56 had noncritical CAD. Whereas the aortic strain (9.11 +/- 3.4 vs. 14.01 +/- 4.1%, p < 0.001) and aortic distensibility (3.98 +/- 1.9 10(-6) cm(2)/dyn vs. 6.33 +/- 2.3 10(-6) cm(2)/dyn, p < 0.001) were lower in the noncritical CAD group, the aortic stiffness index was higher (6.34 +/- 3.9 vs. 3.37 +/- 2.4, p < 0.001) as compared to controls. Serum NGAL levels were higher in the noncritical CAD group (79.29 +/- 38.8 vs. 48.05 +/- 21.4 ng/ml, p < 0.001). NGAL levels were negatively correlated with aortic strain (p < 0.01, r = 0.57) and distensibility (p < 0.001, r = 0.62), but positively correlated with the aortic stiffness index (p < 0.001, r = 0.72). Conclusion: We show that in patients with noncritical CAD, the degree of aortic stiffness and NGAL levels are higher. These markers can be used as tools for further risk stratification of patients with noncritical CAD. (C) 2014 S. Karger AG, Basel
