The predicting efficacy of three-dimensional speckle tracking imaging for major adverse cardiac events in myocardial infarction patients after percutaneous coronary intervention
Objective To investigate the predicting efficacy of three-dimensional speckle tracking imaging(3D-STI)for major adverse cardiac event(MACE)in myocardial infarction(MI)patients after percutaneous coronary intervention(PCI).Methods Eighty-six MI patients who underwent PCI in Affiliated Jinhua Hospital,Zhejiang University School of Medicine from June 2019 to July 2021 and were followed up until August 2022 were retrospectively selected.They were divided into observation group and control group based on follow-up results.The left ventricular global longitudinal peak strain(GLS),global circumferential peak strain(GCS),global radial peak strain(GRS),global area strain(GAS),left ventricular ejection fraction(LVEF)were compared between the two groups.Pearson method was used to analyze the correlation between 3D-STI parameters and MACE.ROC curve was used to analyze the AUC value,sensitivity and specificity of GLS,GCS,GRS,GAS and LVEF parameters in predicting MACE.Results MACE occurred in(observation group)18 patients.GLS,GCS,GRS and GAS absolute value were significantly lower in observation group than in control group(all P＜0.05).GLS,GCS,GRS,GAS and LVEF absolute value gradually increased at 1,6 and 12 months after PCI and were all significantly higher than those before the operation(all P＜0.05).Pearson correlation analysis showed that GLS,GCS,GRS,GAS and LVEF were all negatively correlated with MACE(all P＜0.05).ROC curve analysis showed that the accuracy of predicting MACE using a combination of 3D-STI parameters was significantly higher than that of each parameter,with AUC value of 0.944,sensitivity of 0.889,and specificity of 0.897,respectively.Conclusion Pre-PCI 3D-STI measurement is helpful for predicting post operation MACE in MI patients.
