Abstract: Objective To investigate the predictive value of serum stromal cell-derived factor-1 (SDF-1) and chemokine CCL21 for the clinical prognosis of the elderly patients with acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI). Methods The clinical data of 186 elderly patients with ACS who received PCI in our hospital from 2016 to 2018 were retrospectively analyzed. According to the occurrence of major adverse cardiovascular events (MACE) during 1-year follow-up, the patients were divided into poor prognosis group (86 patients with MACE) and good prognosis group (100 patients without MACE). The serum levels of SDF-1 and CCL21 were measured by enzyme-linked immunosorbent assay (ELISA). The risk factors for poor prognosis of the elderly patients were analyzed by multivariate Logistic regression. Receiver operating characteristic(ROC) curve was drawn to evaluate the diagnostic value of serum SDF-1 and CCL21 for the short-term poor prognosis of the elderly ACS patients after PCI. Results There were significant differences in the levels of heart rate, left ventricular ejection fraction (LVEF), SDF-1, CCL21, low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), troponin and N-terminal pro-B type natriuretic peptide (NT-proBNP), the prevalence of hypertension and the score of GRACE scale between the two groups (P<0.05 or 0.01). Multivariate Logistic regression analysis showed that LVEF, GRACE score, SDF-1 and CCL21 were the independent influencing factors for poor prognosis in the elderly patients. The area under the ROC curve of serum SDF-1 combined with CCL21 in predicting short-term poor prognosis of the elderly patients was 0.930, with a sensitivity and a specificity of 0.841 and 0.857, respectively. Conclusions Serum SDF-1 and CCL21 are the independent influencing factors for short-term poor prognosis of the elderly ACS patients after PCI. The combination of the two indicators has a high predictive value for clinical prognosis in the elderly patients with ACS.
