Objective: To evaluate the changes of myocardial perfusion and left ventricular systolic function in patients with acute myocardial infarction (AMI) after percutaneous coronary intervention (PCI) by myocardial contrast echocardiography (MCE), left ventricular contrast echocardiography (LVO) combined with two-dimensional speckle tracking imaging (2D-STI). Methods: Thirty-seven patients with AMI treated by PCI were selected as the observation group. At the same time, 30 patients with normal cardiac ultrasound results were set as the control group. The control group and the observation group at 1 week after PCI were examined by MCE, LVO and 2D-STI, and reviewed after 1 month. The MCE parameters, left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume (LVESV), left ventricular ejection fraction (LVEF) and left ventricular global longitudinal strain (GLS) were compared between the observation group and the control group, and the correlation between MCE parameters, GLS and LVEF in the observation group and the control group was analyzed. Results: The peak intensity (A), curve slope (β) and regional myocardial blood flow (A×β) of the observation group at 1 month after operation were higher than those at 1 week after operation (P<0.05), but lower than those of the control group (P<0.05). The GLS and LVEF of the observation group at 1 month after operation were higher than those at 1 week after operation (P<0.05), but lower than those of the control group (P<0.05). LVEDV and LVESV decreased (P<0.05), but higher than those in the control group (P<0.05). There was a correlation between MCE parameters, GLS and LVEF in the observation group and the control group. Conclusion: MCE, LVO combined with 2D-STI can quantitatively evaluate myocardial perfusion and left ventricular systolic function in patients with AMI after PCI, and provide a reliable reference for the evaluation of curative effect after PCI.
