文摘

Our previous study showed that patients with acute myocardial infarction (AMI) had lower levels of vaspin than patients without AMI. The aim of this study was to investigate the clinical significance of vaspin in patients with AMI.

Methods

A total of 80 patients with AMI were enrolled. Plasma vaspin levels, clinical parameters, lipid profile, C reactive protein (CRP) were measured. All the patients were followed-up for 24±2 months for the occurrence of major adverse major cardiac events (MACEs).

Results

During the follow-up, 48 patients experienced a MACE. The plasma vaspin concentrations in the MACEs-positive group were lower than those in the MACEs-negative group (0.156 ± 0.015 vs 0.314 ± 0.229ng/mL, p<0.001). Receiver operating characteristic curves showed that circulating vaspin concentration significantly differentiated patients with MACEs (p<0.001). The optimal cutoff value for predicting MACE was 0.259ng/mL. Then the patients were divided into vaspin>0.259ng/mL group and vaspin<0.259ng/mL group according to the plasma vaspin levels. Forty-five patients (74%) in the vaspin<0.259ng/mL group and three (16%) patients in the vaspin>0.259ng/mL group experienced a MACE. Multivariate survival analyses showed that the vaspin level (hazard ratio, HR 0.423) independently predicted the occurrence of MACEs. Compared with the results of echocardiography at admission, the improvement of LVEF in the vaspin>0.259ng/mL group was significant (54.3±7.6% to 61.2±4.7%, p<0.001), but the change of LVEF in the low vaspin group was not significant (51.3±9.7% to 52.5±10.9%).

Conclusions

Vaspin might be a useful predictive biomarker in patients with AMI, and patients with low vaspin levels might have a high risk of a MACE. In addition, vaspin might have protective effects on the improvement of LVEF after AMI.
