Abstract:
Objective To investigate whether soluble lectin-like oxidized low-density lipoprotein receptor-1 (sLOX-1) as the early diagnostic biomarker of acute ST elevation myocardial infarction (STEAMI).Methods Sixty-five patients with STEAMI and 30 patients with stable coranary heart disease or other heart disease(control group) were enrolled as our subjects.Serum sLOX-1 levels were measured.Results The median(P25,P75) of Serum sLOX-1 in the patients with STEMI were 210.0 (130.0,356.0) ng/L,significantly higher than that of control group(65.5 (55.2,85.2) ng/L,Z =6.17,P ＜ 0.001).Logistic regression analysis revealed that sLOX-1 alone was an independent factor associated with STEAMI (B =0.036,P ＜ 0.001).The area under the ROC curve of sLOX-1 for detecting STEMI was 0.895,and 95％ CI was 0.831-0.959 (P＜0.001).Taking sLOX-1 =87.5 ng/L as cut-off value,the sensitivity was 89.6％ and specificity was 82.4％for the diagnosis of STEAMI.Conclusion Serum sLOX-1 was significantly higher in the STEAMI and it might served as the early diagnostic marker for STEAMI.
