Accordingly, we evaluate the association between serum leptin and future CV events in patients with coronary artery disease (CAD).Patients and methods: This study enrolled 98 patients with CAD from January to December 2012. The primary endpoint included incidences of major adverse CV events and hospitalization. Patients follow-up had been completed on June 30, 2017.Results: After a median follow-up of 52 months, 43 CV events had occurred. Patients with CV events had higher systolic blood pressure (P = 0.030), total cholesterol (P = 0.034), C-reactive protein (P = 0.018), and serum leptin levels (P = 0.001) than those without CV events. Kaplan&ndash;Meier analysis showed greater cumulative incidences of CV events in the high leptin group (median leptin concentration >6.03 ng/mL) than in the low leptin group (log-rank P = 0.012). Multivariate Cox regression analysis showed that triglyceride (HR: 1.010; 95% CI: 1.001&ndash;1.018; P = 0.022) and leptin levels (HR: 1.054; 95% CI: 1.026&ndash;1.082; P < 0.001) were independently associated with CV events in patients with CAD.Conclusion: Serum leptin levels could serve as a biomarker for future CV events in patients with CAD.
