Abstract

Objectives: To investigate the correlation of serum levels of bridging integrating factor 1 (BIN1) with acute myocardial infarction (AMI) and Killip class of the patients.

Methods: We retrospectively collected the data from 94 patients with AMI and 30 healthy individuals for analysis of the correlations of serum BIN1 levels with Killip class, TIMI scores, and neutrophil-to-lymphocyte ratio (NLR). We also assessed the diagnostic value of BIN1 combined with NLR for AMI.

Results: Serum BIN1 levels were significantly lower in AMI patients than in the healthy individuals (P=0.032). The AMI patients with Killip class I had significantly lower serum BIN1 levels than the healthy individuals (P=0.008). Serum BIN1 level was an independent predictor of AMI with a predictive value of 0.630 (95% CI: 0.513-0.748) at the optimal cutoff level of 0.341 ng/mL, a specificity of 50%, and a sensitivity of 78.5%. Serum BIN1 level was also an independent predictor for Killip class I group in the AMI patients with a predictive value of 0.672 (95% CI: 0.548-0.797) at the optimal cutoff level of 0.287 ng/mL, a specificity of 74.1%, and a sensitivity of 60%. For AMI diagnosis, the combination of NLR and serum BIN1 level had a predictive value of 0.811 (95% CI: 0.727-0.895) at the optimal cutoff level of 0.548 ng/mL, with a specificity of 92.6% and a sensitivity of 62.2%. There was a positive correlation between serum BIN1 level and TIMI score in AMI patients (r=0.186, P=0.003).

Conclusions: BIN1 is correlated with AMI and can be helpful for predicting short-term prognosis of the patients, and BIN1 combined with NLR has a high diagnostic value for AMI.
