Abstract:

Objective To explore the predicting value of neutrophil to lymphocyte ratio (NLR) combined with global registry of acute coronary events (GRACE) score on in-hospital major adverse cardiovascular events (MACE) of postoperative primary percutaneous coronary intervention (PCI) of patients with acute ST-segment elevation myocardial infarction (STEMI). Methods From September 1, 2018 to December 31, 2019, a total of 275 patients with acute STEMI underwent primary PCI who visited the Department of Cardiology, Hebei General Hospital were enrolled and divided into the MACE group (n=35) and the non-MACE group (n=240), postoperative PCI in-hospital MACE included all-cause mortality, cardiogenic shock, in-hospital repeat revascularization, fatal arrhythmia, cardiac arrest. The clinical data was recored, the independent risk factors of in-hospital MACE were analyzed. The receiver operating characteristic (ROC) curve was plotted to analyze the predictive value of NLR, GRACE score and the two combined for in-hospital MACE of postoperative PCI in acute STEMI patients. Results Compared with the non-MACE group, increased age, GRACE score, CRUSADE score and NLR and decreased estimated glomerular filtration rate were detected in the MACE group (all P<0.05). Multivariate Logistic regression analysis showed that GRACE score and NLR were independent risk factors of in-hospital MACE of postoperative PCI in patients with acute STEMI (all P<0.05). ROC curve indicated that GRACE score, NLR had certain predictive value for in-hospital MACE, while the two combined had a greater areas under curve for better predicting in-hospital MACE. Conclusion GRACE score and NLR are independent risk factors for in-hospital MACE of postoperative PCI in acute STEMI patients, the two combined has a greater predictive value for in-hospital MACE.
