    Abstract:
    BACKGROUND: The monocyte to high-density lipoprotein cholesterol ratio (MHR) has been demonstrated as a new marker of inflammation. However, at present, the prognostic value of MHR in type 2 diabetes mellitus (T2DM) accompanied with non-ST-segment elevation acute coronary syndrome (NSTE-ACS) undergoing percutaneous coronary intervention (PCI) is unclear. METHODS: T2DM patients with NSTE-ACS undergoing PCI were consecutively enrolled from January 1, 2010 to December 31, 2014 and divided according to MHR value tertiles. Baseline, procedural, and follow-up data were collected. The primary outcomes were in-hospital major adverse clinical events (MACE). The prespecified secondary outcomes included any bleeding [as indicated by Bleeding Academic Research Consortium definition (BARC) grades 1-5] and death during follow-up. RESULTS: Of the 1,405 enrolled patients, the rates of in-hospital MACE (0.2%, 0.2%, and 1.3%, P=0.043) and bleeding (12.4%, 12.2%, and 17.1%, P=0.048) increased significantly in high MHR tertiles. After 1 year of follow-up, the rates of bleeding (15.0%, 14.5%, and 22.2%, P=0.002) and all-cause death (1.5%, 1.7%, and 4.3%, P=0.010) were higher in higher MHR tertiles. Our results also suggested that MHR was an independent predictor of in-hospital MACE [adjusted odds ratio =8.36; 95% confidence interval (CI): 1.57-44.47; P=0.013] and long-term bleeding (adjusted hazard ratio =1.21; 95% CI: 1.07-1.37; P=0.002). Receiver-operating characteristic curve analysis indicated that MHR >0.022 had a sensitivity of 75.0% and specificity of 72.7% for predicting in-hospital MACE [area under the curve (AUC) =0.722; 95% CI: 0.51-0.933; P=0.040]. Furthermore, Kaplan-Meier curves showed that a higher risk of all-cause death in long-term follow-up was prevalent in patients with high MHR (P=0.033). CONCLUSIONS: The increased level of MHR was related to in-hospital MACE and long-term bleeding events in T2DM patients with NSTE-ACS undergoing PCI.
