| Abstract |
The purpose of this study was to summarize the clinical characteristics and risk factors of major adverse cardiovascular events (MACEs) in patients who had had acute myocardial infarction (AMI) within 1 year of percutaneous coronary intervention (PCI). A total of 421 AMI patients who were treated with PCI and experienced MACEs within 1 year of their admission were included in this retrospective study. In addition, patients were matched for age, sex, and presentation with 561 patients after AMI who had not had MACEs. The clinical characteristics and risk factors for MACEs within 1 year in AMI patients were investigated, to develop a nomogram for MACEs based on univariate and multivariate analyses. The C statistic was used to assess the discriminative performance of the nomogram. In addition, calibration curve and decision curve analyses were conducted to validate the calibration performance and utility, respectively, of the nomogram. After univariate and multivariate analyses, a nomogram was constructed based on age (odds ratio (OR): 1.030; 95% confidence interval (CI): 1.014-1.047), diabetes mellitus (OR: 1.667; 95% CI: 1.151-2.415), low-density lipoprotein cholesterol (OR: 1.332; 95% CI: 1.134-1.565), uric acid (OR: 1.003; 95% CI: 1.001-1.005), lipoprotein (a) (OR: 1.003; 95% CI: 1.002-1.003), left ventricular ejection fraction (OR: 0.929; 95% CI: 0.905-0.954), Syntax score (OR: 1.075; 95% CI: 1.053-1.097), and hypersensitive troponin T (OR: 1.002; 95% CI: 1.002-1.003). The C statistic was 0.814. The calibration curve showed good concordance of the nomogram, while decision curve analysis demonstrated satisfactory positive net benefits. We developed a convenient, practical, and effective prediction model for predicting MACEs in AMI patients within 1 year of PCI. To ensure generalizability, this model requires external validation.
