Abstract: This paper discussed the effect of spot tracking echocardiography on left ventricular remodeling (LVR) after percutaneous coronary intervention(PCI) in acute myocardial infarction(AMI) patients. 96 patients with AMI undergoing emergency PCI were selected and divided into LVR group and non-LVR group, and spot tracking echocardiographic parameters of 24 h and 6 months after PCI were collected. It is found that the rate of LVR after PCI in all patients was 35.42%. Compared with the postoperative parameters of 24 h after PCI, LVESV and LVEDV in LVR group after PCI for 6 months increased but LVEF decreased significantly, while LVEF in non-LVR group after PCI for 6 months was higher significantly (P<0.05). LVESV, LVEDV and LVEF after PCI for 6 months of the two groups had significant differences (P<0.05). Compared with non-LVR group, left ventricular GLS, GRS and GCS in LVR group were lower significantly, left ventricular longitudinal and radial Ts-SD were higher significantly (P<0.05). Multivariate logistic analysis showed that GLS, GRS and GCS were independent predictors of LVR after PCI in AMI patients. ROC curve analysis showed that AUC were gradually decreased as GLS>GCS>GRS. In a word, GLS, GCS and GRS examined by spot tracking echocardiography can objectively predict LVR risk after PCI in AMI patients, and GLS is the most significant predictor.
