Abstract
Objective We aimed to explore the relationship between neutrophil-to-lymphocyte ratio (NLR) at three timepoints and prognosis of patients with non-ST-segment elevation acute coronary syndrome (NSTE-ACS) undergoing elective percutaneous coronary intervention (PCI) within 1 year of PCI. Methods This retrospective study enrolled 231 patients with NSTE-ACS who received PCI and were followed for 1 year after PCI. The study population was divided into major adverse cardiovascular and cerebrovascular events (MACE) and non-MACE groups. Results In total, 214 patients completed the 1-year follow-up; 32 patients (15.0%) had MACE and 182 (85.0%) had no MACE. The MACE and non-MACE groups differed significantly in age, preoperative neutrophil count, preoperative and postoperative NLR, proportion of three-vessel lesion disease, preoperative lymphocyte count, postoperative lymphocyte count within 24 hours, postoperative lymphocyte count over 24 hours, and left ventricular ejection fraction (LVEF). Multivariate logistic regression analysis showed that preoperative NLR, postoperative NLR within 24 hours, age, and LVEF values were independent risk factors for MACE in patients with NSTE-ACS after elective PCI. Conclusion Compared with preoperative NLR, postoperative NLR (within 24 hours) may have a stronger ability to predict the occurrence of MACE in NSTE-ACS patients within 1 year after elective PCI.
