Objective To explore the relationship between estimated pulse wave velocity (ePWV) and major adverse cardiac events (MACE) in patients with stable coronary artery disease. Methods Data extracted from a study on stable coronary artery disease in the Dryad database, an open access database, was selected for secondary analysis. All patients with stable coronary artery disease in the original data were included, and patients were divided into groups according to the occurrence of MACE and the median ePWV level, respectively. Cox proportional hazards models were used to analyze the relationship between ePWV and MACE. ROC curve was used to evaluate the predictive value of ePWV for MACE in patients with stable coronary artery disease. Results EPWV was significantly higher in patients with MACE than in those without MACE (P=0.002). The incidence of MACE was significantly higher in patients with high ePWV than in those with low ePWV (P=0.042). In multivariate Cox regression analysis, ePWV was independently associated with the MACE in patients with stable coronary artery disease (HR=1.380, 95%CI: 1.109~1.717, P=0.004). ROC curve analysis showed that the area under the ROC curve of ePWV to predict MACE in patients with stable coronary artery disease was 0.677 (P=0.003). Conclusion EPWV is independently associated with the MACE in patients with stable coronary artery disease, and it could be used to predict the incidence of MACE in patients with stable coronary artery disease.
