ObjectiveThe diagnostic significance of plasma soluble lectin-like oxidized low-density lipoprotein receptor-1(sLOX-1) for non-ST segment elevated myocardial infarction (NSTEMI) and ST segment elevated myocardial infarction (STEMI) were explored by this study.MethodsIn this study, 107 acute NSTEMI, 223 acute STEMI and 107 healthy subjects, and hypoxic (1%02) ventricular cardiomyocytes H9c2 were used.ResultsThe significantly up-regulated plasma sLOX-1 levels in acute NSTEMI and STEMI patients compared to healthy subjects (p<0.001). Both male and female NSTEMI and STEMI groups had remarkably higher concentrations of plasma sLOX-1 levels than controls (p<0.001). The circulating levels of sLOX-1 expression obviously elevated in elderly aging (60-75 years) than younger aging (30-45 years) both male and female in healthy subjects as well as NSTEMI and STEMI (p<0.001). Altered levels of sLOX-1 in blood plasma revealed a significant discrimination with high sensitivity and specificity between healthy with NSTEMI and STEMI subjects with AUC= 0.916 and AUC= 0.925 respectively. Moreover, LOX-1 levls were highly released from 6hour, 12hour and 18hour hypoxic injured H9c2 cells than normoxic cell (p<0.001), reflected circulating plasma sLOX-1 in AMI patients.ConclusionElevated levels of plasma sLOX-1concentrations might be used as a clinical biomarker for early recognition of NSTEMI and STEMI patients. Multicenter larger scale studies are necessary before use in clinical practice.© 2022 Ali Sheikh MS et al.
