Associations between plasma nesfatin-1 levels and the presence and severity of coronary artery disease

Nesfatin-1 is a recently identified anorexigenic peptide mainly secreted from the brain and adipose tissue. Although nesfatin-1 may have pro-inflammatory and apoptotic properties, the association between plasma nesfatin-1 levels and coronary artery disease (CAD) has not been clarified yet. We investigated plasma nesfatin-1 levels in 302 patients undergoing elective coronary angiography. Of the 302 study patients, CAD was present in 172 (57%), of whom 67 had 1-vessel, 49 had 2-vessel, and 56 had 3-vessel disease. Compared with 130 patients without CAD, 172 with CAD had higher plasma nesfatin-1 levels (median 0.21 vs. 0.17 ng/mL, P 50% stenotic coronary vessels: 0.17 in CAD(−), 0.20 in 1-vessel, 0.21 in 2-vessel, and 0.22 ng/mL in 3-vessel disease ( P 0.19 ng/mL) was found in 43% of patients with CAD(−), 55% of those with 1-vessel, 55% of those with 2-vessel, and 68% of those with 3-vessel disease ( P 50% stenotic coronary segments ( r = 0.14, P 0.19 ng/mL ( P
