| description | Abstract Background Concurrent anemia is associated with an increased risk of major adverse cardiac events (MACE) in patients with myocardial infarction. The study aimed to assess the value of anemia and preoperative hemoglobin levels in predicting clinical outcomes in stable coronary artery disease (SCAD) patients receiving percutaneous coronary intervention (PCI). Methods This is a secondary analysis based on a retrospective cohort study in which 204 patients with SCAD who received PCI were recruited. The primary outcome was major adverse cardiac events (MACE; including all-cause mortality, non-fatal myocardial infarction, and non-fatal stroke) and the secondary outcome was cardiovascular events (cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke). Results During a median follow-up of 783 days, MACE occurred in 28 patients. In multivariate COX regression analysis, after adjusting for potential confounding factors, low hemoglobin level independently predicted worse prognosis at the primary endpoint (HR = 0.72, 95% CI 0.56 to 0.93, p = 0.012) and the secondary endpoint (HR = 0.71, 95% CI 0.52 to 0.96, p = 0.027) after PCI. The receiver operating characteristic curve (ROC) showed that the best threshold for hemoglobin to predict MACE was 12.25 g/dl. In Kaplan-Meier analysis, hemoglobin < 12.25 g/dl predicted worse prognosis in MACE (p < 0.001). Conclusions Low preoperative hemoglobin level increased the risk of MACE in SCAD patients receiving PCI and the optimal threshold for predicting MACE is 12.25 g/dl. |
