摘要
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 followup 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 longterm 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.
