| Abstract |
Percutaneous coronary intervention-related periprocedural myocardial infarction (PCI-RPMI) has now been definitively linked in large data sets to long-term adverse outcomes. It is more likely that the relationship is caused by the underlying predisposing factors that led to the PCI-RPMI, such as plaque vulnerability. Lectin-like oxidized low-density lipoprotein receptor-1 (LOX-1) is involved in multiple phases of vascular dysfunction, including atherosclerotic plaque formation and/or vulnerability. The purpose of this study was to determine whether soluble LOX-1 (sLOX-1) is associated with myocardial necrosis in elective native single-vessel PCI (NSV-PCI). From January 2010 to January 2012, 214 consecutive stable patients undergoing elective NSV-PCI were enrolled. Troponin T, CK and CK-MB were performed to screen for PCI-induced myocardial necrosis after the procedure, and PCI-RPMI was defined as three times the ULN of CK, which was confirmed by the elevation of the CK-MB and troponin T. According to the cardiac biomarkers result, patients were divided into two groups [PCI-RPMI(+) and PCI-RPMI(-)]. sLOX-1 levels were measured in serum by ELISA. Of the 214 patients who underwent NSV-PCI, 33 (15.4 %) patients developed PCI-RPMI. The results of this study showed that among patients undergoing elective NSV-PCI, those with PCI-RPMI had significantly higher circulating sLOX-1 levels than those without (167 ± 89 vs. 99 ± 68 pg/mL; p < 0 0.001). There were high correlations between sLOX-1 levels and CK and CK-MB values (r = 0.677 and r = 0.682, respectively; p < 0.001). Our study demonstrated that circulating sLOX-1 levels were associated with PCI-RPMI, which might predict periprocedural myocardial necrosis in elective NSV-PCI. Importantly, the study speculates that the level of sLOX-1 may help to identify patients at risk for PCI-RPMI before the procedure. sLOX-1 may provide new insights into not only risk stratification, but also therapeutic strategies for elective PCI.
