Abstract:Objective To explore the prognostic value of electrocardiogram T-wave changes combined with serum homocysteine (Hcy) in patients with myocardial infarction (MI) after percutaneous coronary intervention (PCI). Methods A total of 76 MI patients admitted to Suzhou Hospital of Integrated and Western Medicine from January 2017 to July 2022 were selected for PCI. According to the occurrence of major adverse cardiovascular events (MACE) within one year after surgery, they were divided into good prognosis group and poor prognosis group. The general data, electrocardiogram T-wave changes and serum Hcy levels of MI patients in the two groups were compared to analyze the factors affecting the prognosis of MI patients after PCI, and the receiver operating characteristic (ROC) curve was used to analyze the value of electrocardiogram T-wave changes combined with serum Hcy in evaluating the prognosis of MI patients after PCI. Results In 76 MI patients who underwent PCI, a total of 54 patients did not develop MACE and 22 patients developed MACE within one year after surgery. The proportion of T wave inversion and serum Hcy level in the poor prognosis group were higher than those in the good prognosis group, and the differences were statistically significant (P<0.05). Logistic regression analysis showed that serum Hcy level and T wave inversion were independent risk factors for poor prognosis of MI patients after PCI (OR>1,P<0.05). ROC curve analysis showed that the AUC value of Hcy level and T-wave inversion in assessing the prognosis of MI patients after PCI was 0.773 (95%CI: 0.662-0.861) and 0.771 (95%CI: 0.660-0.860), respectively, and the AUC value predicted by the combination of the two was 0.904 (95%CI: 0.815-0.960). Conclusion The changes of electrocardiogram T wave and serum Hcy level have certain predictive value for the prognosis of MI patients after PCI, and the combined value is higher.
