Baseline Serum sLOX-1 Concentrations Are Associated with 2-Year Major Adverse Cardiovascular and Cerebrovascular Events in Patients after Percutaneous Coronary Intervention

BACKGROUND: Soluble lectin-like oxidized low-density lipoprotein receptor-1 (sLOX-1) may be a potential biomarker of coronary artery disease (CAD) and stroke. OBJECTIVE: We aimed to investigate the association and prognostic value of elevated sLOX-1 concentrations with regard to long-term major adve...

Sumario:BACKGROUND: Soluble lectin-like oxidized low-density lipoprotein receptor-1 (sLOX-1) may be a potential biomarker of coronary artery disease (CAD) and stroke. OBJECTIVE: We aimed to investigate the association and prognostic value of elevated sLOX-1 concentrations with regard to long-term major adverse cardiovascular and cerebrovascular events (MACCEs) in patients with CAD undergoing primary percutaneous coronary intervention (PCI). METHODS: A total of 1011 patients were enrolled. Serum sLOX-1 concentrations were detected by the enzyme-linked immunosorbent assay (ELISA). Patients were followed for 2 years. Multivariate Cox regression and Kaplan-Meier survival curve were explored to assess the association between sLOX-1 and MACCEs. A receiver operating characteristic (ROC) curve was used to evaluate the diagnostic efficacy of sLOX-1. RESULTS: Two-year MACCEs were associated with serum sLOX-1 concentrations (HR 1.278, 95% CI 1.019-1.604, P = 0.034), left main disease (HR 2.938, 95% CI 1.246-6.925, P = 0.014), small-caliber stents used (HR 2.207, 95% CI 1.189-4.095, P = 0.012), and total stent length (HR 1.057, 95% CI 1.005-1.112, P = 0.030). Serum sLOX-1 concentration ≥ 1.10 ng/ml had maximum sensitivity and specificity in predicting the occurrence of 2-year MACCEs (P < 0.001). Patients with higher serum sLOX-1 concentrations showed a significantly higher incidence of MACCEs in the Kaplan-Meier curve (P < 0.001). The combination of any of the risk factors identified in multiple Cox regression was associated with a stepwise increase in MACCE rate (P < 0.001). CONCLUSIONS: High baseline serum sLOX-1 concentration predicts 2-year MACCEs and shows an additional prognostic value to conventional risk factors in patients after primary PCI. sLOX-1 determination might play a complementary role in the risk stratification of patients with CAD treated with PCI.
