BACKGROUND: LR11 (also so called SorLA or SORL1) is a novel marker of intimal smooth muscle cell (SMC) proliferation. Vascular SMCs play important roles in the development of atherosclerosis interacting with macrophages in a vulnerable plaque of patients with acute coronary syndrome (ACS).The present study determines whether soluble LR11 (sLR11) is associated with ACS.
METHODS: We studied 100 patients with coronary artery disease (CAD) comprising 50 consecutive patients with acute coronary syndrome (ACS; mean age 62.3±13.0 years; male 78.0%) who were successfully treated with percutaneous coronary intervention and 50 age- and sex-matched stable angina pectoris (SAP) patients as control. Concentration of sLR11 was measured by sandwich enzyme-linked immunosorbent assay method.
RESULTS: Circulating sLR11 was significantly increased in patients with ACS compared with SAP (9.88±2.78 vs. 8.18±1.11 ng/ml, p<0.01). Multivariate logistic regression analysis indicated that sLR11 was independently associated with ACS (odds ratio (OR), sLR11 quartile increment, 2.18, 95% confidence interval (CI) 1.21-4.19, p<0.01). Among various biomarkers of acute coronary syndrome, hsCRP were significantly correlated with LR11 (r=0.480, p<0.01).
CONCLUSIONS: There is a statistical significant association between LR11 and ACS and may be a useful biomarker for the development of acute coronary syndrome.
