Correlation between T wave morphology and the risk of tachyarrhythmia after percutaneous coronary intervention in patients with acute myocardial infarction
Objective To explore the correlation between T wave morphology and the risk of tachyarrhythmia after percutaneous coronary intervention(PCI)in patients with acute myocardial infarction(AMI).Methods 169 AMI patients who received PCI in Chengdu Hospital of Integrated Traditional Chinese and Western Medicine from April 2022 to January 2024 were taken as the research object.48 h after operation,the patients were divided into two groups according to whether they had tachyarrhythmia or not.The general data,laboratory examination indexes and T wave morphology related parameters of the two groups were compared.Multivariate logistic regression was used to analyze the related factors affecting the occurrence of arrhythmia after the treatment.ROC curve was drawn and AUC was calculated to analyze the correlation between T wave morphology and the risk of arrhythmia.Results Within 48 hours after admission,45 cases(26.63％)developed arrhythmia.The blood neutrophil/lymphocyte(NLR),high-sensitivity C-reactive protein(hs-CRP)and left ventricular end systolic diameter(LVESD)in the occurrence group were higher than those in the non-occurrence group[(4.46±1.52)vs.(2.78±0.82)、(2.61±0.71)mg/L vs.(1.94±0.41)mg/L、(40.54±3.65)mm vs.(38.25±5.97)mm];the left ventricular ejection fraction(LVEF)in the occurrence group was lower than that in the non-occurrence group[(45.61±5.31)％vs.(55.84±6.21)％](all P＜0.05).The QT interval,Tp-Te interval,corrected Tp-Te interval(TP-TEC)and corrected QT interval(QTC)in the occurrence group were higher than that in the non-occurrence group;the incidence of T-wave inversion in the occurrence group was higher than that in the non-occurrence group(73.33％vs.28.23％)(all P＜0.05).Multivariate logistic regression analysis showed that hs-CRP(OR=19.495,95％CI 1.907-199.292),NLR(OR=18.807,95％CI 3.871-91.379),Tp-Tec(OR=1.025,95％CI 1.096-1.680),Tp-Te/QT(OR=1.025,95％CI 1.002-1.049)and T wave morphology(OR=8.695,95％CI 3.267-23.139)were the relative factors of arrhythmia.The ROC curve showed that the AUC of T wave morphology and the risk of arrhythmia was 0.726(P＜0.05).Conclusion hs-CRP,NLR,Tp-Tec,QTc,Tp-Te/QT and T-wave morphology are the related factors of arrhythmia,and T-wave morphology has a higher correlation with postoperative arrhythmia.
