Methods: 192 patients with AMI who underwent DCB treatment in the Cardiology Department of Qingdao Haici Hospital from January 2021 to December 2023 were continuously enrolled. According to 1-year MACE event incidence after DCB treatment, they were divided into the non-MACE group (156 cases) and the MACE group (36 cases). The patients’ general information, intraoperative and postoperative information, treatment situation, and 1-year follow-up information were collected, and Cox regression analysis was used to analyze the influencing factors of MACE events in patients with AMI after DCB treatment, and the Receiver Operating Characteristic (ROC) curve was drawn to evaluate the predictive ability of the influencing factors. Results: The multivariate Cox regression analysis showed that STEMI (HR = 2.187, 95% CI=1.016~4.708, P < 0.05) and target vessel as LCX (HR = 0.021, 95% CI = 0.006~0.070, P < 0.05) and RCA (HR = 0.028, 95% CI = 0.010~0.083, P < 0.05) were independent predictors of MACE events in patients with AMI after DCB treatment within 1 year. The ROC curve analysis showed that the predictive ability of combined STEMI and target vessel as RCA and LCX in predicting MACE events within 1 year after DCB treatment was high (AUC = 0.827,95%CI = 0.720~0.934, P < 0.05). Conclusion: Compared with non-ST-segment elevation myocardial infarction, ST-segment elevation myocardial infarction has a certain predictive value for the occurrence of MACE events in patients with AMI treated with DCB within 1 year;compared with target vessel for LAD, target vessels for RCA and LCX have a certain predictive value for the occurrence of MACE events in patients with AMI treated with DCB within 1 year and the combined prediction of MACE events has a higher predictive ability.展开更多
