Serum Vaspin as a Predictor of Adverse Cardiac Events in Acute Myocardial Infarction

Background The involvement of vaspin (visceral adipose tissue–derived serpin) in the development of atherosclerotic cardiovascular diseases has been documented. This study was designed to explore the prognostic value of serum vaspin in patients with acute myocardial infarction (AMI). Methods and Results We included 1036 AMI patients in a cohort study and determined the association between serum vaspin and major adverse cardiac events (MACE) using Cox regression analysis. The receiver operating characteristic curve indicated that serum vaspin could significantly differentiate patients with MACE, and the optimal cutoff value was 0.62 ng/mL. The Kaplan–Meier survival curve showed that patients with lower vaspin levels had higher incidence of MACE. Multivariate Cox regression analysis revealed that low vaspin was an independent predictor of MACE (hazard ratio: 0.74; 95% CI, 0.48–0.96; P=0.029), together with age; previous histories of AMI, heart failure, hypertension, and diabetes mellitus; Killip class; revascularization; CRP (C‐reactive protein); and NT‐proBNP (N‐terminal pro–B‐type natriuretic peptide). Integrated discrimination and net reclassification improvements for MACE were significantly improved by addition of vaspin to the model of traditional risk factors. Moreover, low vaspin was a valuable predictor of heart failure hospitalization (hazard ratio: 0.58; 95% CI, 0.37–0.89; P=0.005) and recurrent AMI (hazard ratio: 0.72; 95% CI, 0.53–0.95; P=0.036) after adjustment for conventional cardiovascular risk factors. Conclusions Our study suggests that serum vaspin is a significant prognostic marker of MACE in AMI patients.
