Abstract:

Objective To investigate the predictive values of ALB-dNLR score on long-term prognosis of patients with acute coronary syndrome (ACS) after percutaneous coronary intervention (PCI). Methods A total of 1 744 patients with ACS after PCI were consecutively enrolled. The clinical and laboratory data of all the subjects were collected. After discharge, patients were followed up by outpatient visit and telephone call. Major adverse cardiovascular events (MACE) were recorded. The receiver operating characteristic (ROC) curve was used to determine the best cutoff value of each inflammatory markers for predicting MACE. The correlation between ALB and dNLR and other inflammatory markers was analyzed. Kaplan-Meier curve and Cox regression models were used to determine the influencing factors of MACE. Results A total of 1 539 patients with ACS after PCI were enrolled in our study. The median follow-up time was 1 141 days, including 60 patients in the MACE group and 1 479 patients in the non-MACE group. The neutrophil count, dNLR, neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), monocyte to lymphocyte ratio (MLR), systemic immune-inflammation index (SII), creatine kinase MB isoenzyme and creatinine levels were higher in the MACE group than those in the non-MACE group, and the lymphocyte count and ALB level were lower. The area under the ROC curve of ALB, dNLR, ALB-dNLR, NLR, PLR, MLR and SII were 0.619, 0.600, 0.645, 0.619, 0.576, 0.587 and 0.611 (all P<0.05). ALB was negatively correlated with dNLR, NLR, PLR, MLR and SII, while dNLR was positively correlated with NLR, PLR, MLR and SII (all P<0.05). ALB≤40.72 g/L, dNLR≥2.30 and ALB-dNLR score were found to be independent risk indicators for MACE in ACS patients after PCI (P<0.05). Conclusion ALB-dNLR score is an independent predictor of MACE in ACS patients after PCI, which is expected to be a new prognostic index.
