OBJECTIVES: High levels of soluble receptor for advanced glycation end products (sRAGE) have been shown to have an atheroprotective role; however, no data are available on this molecule in acute coronary syndromes (ACS). We evaluated sRAGE levels in patients with non-ST segment elevation ACS (NSTE-ACS) or with chronic stable angina. METHODS: We studied 265 patients, 190 of whom had NSTE-ACS and 75 had chronic stable angina. RESULTS: Plasma sRAGE values were comparable in the two groups (P=0.19). However, in the patients with NSTE-ACS, sRAGE levels were significantly higher in patients with cardiac troponin-I (cTnI) of more than or equal to 0.04 µg/l compared with those with cTnI of less than 0.04 µg/l [758 (493-1536 ) pg/ml vs. 454 (167-899) pg/ml; P=0.0037]. A significant correlation (r=0.323, P=0.0045) was found between sRAGE and cTnI levels in patients with NSTE-ACS. CONCLUSION: Plasma sRAGE levels are elevated in patients with NSTE-ACS with positive cTnI, suggesting that they could be related to myocardial cell damage.
