Abstract:
Objective To analyze correlation between T-wave parameters and life-threatening arrhythmia(LTA)after percutaneous coronary intervention(PCI)in patients with acute myocardial infarction(AMI).Methods A total of 232 AMI patients admitted to Huzhou No.1 People's Hospital from May 2021 to March 2023 and treated with PCI were selected as subjects.They were divided into LTA group(n=36)and non LTA group(n=196)based on the presence of LTA within 72 hours after PCI.General information,clinical data,and T-wave parameter of two groups of patients were compared,and multivariate Logistic regression were used to analyze influencing factors.Results There were statistically significant difference in age,resting heart rate(RHR),Tp-Te/QT,and Tp-Tec between two groups(P＜0.05).The difference in anterior wall myocardial infarction,creatinine,and high-sensitivity cardiac troponin T(hs-cTnT)between two groups were statistically significant(P＜0.05).Age,RHR,Tp-Te/QT,Tp-Tec and hs-cTnT were the influencing factors of LTA in AMI patients after PCI(P＜0.05).Multivariate Logistic regression showed that age,Tp-Te/QT and hs-cTnT were independent influencing factors of LTA in AMI patients after PCI(P＜0.05).Conclusion AMI patients have a higher risk of life-threatening arrhythmia after PCI.Age,Tp-Te/QT and hs-cTnT are independent influencing factors of LTA after PCI.
