Analysis of the Predictive Value of ST-T Segment Regression in Patients with Acute Myocardial Infarction after PCI
Objective:To analyze the value of ST-T segment regression in predicting the prognosis of patients with acute myocardial infarction(AMI)after percutaneous coronary intervention(PCI).Methods:The data of 100 AMI patients undergoing PCI treated in Jinan Third People's Hospital from January 2020 to January 2024 were retrospectively analyzed.According to the occurrence of adverse cardiovascular events(MACE)within 1 month after operation,they were divided into good prognosis group and poor prognosis group.The influencing factors for the occurrence of MACE in the two groups were analyzed,and the Receiver Operating Characteristic curve was drawn to explore the predictive value of the influencing factors.Results:Among 100 patients with AMI,11(11.00%)had MACE.The ST-T segment of ECG in the poor prognosis group was lower than that in the good prognosis group from preoperative to postoperative 1 and 2 h,the differences were statistically significant(P<0.05).The regression degree of ST-T segment in ECG from preoperative to 1 and 2 h after PCI was a high risk factor for MACE in AMI patients,the differences were statistically significant(P<0.05).The area under the curve for predicting the prognosis of AMI patients after PCI was 0.707 and 0.704,respectively.Conclusion:The lower degree of ST-T segment of ECG can predict the poor prognosis of AMI patients after PCI,which has certain predictive value.
