Abstract

Abstract. Objective: To observe and study 2D- STI technique to investigate the coronary artery disease after PCI in patients with preoperative left ventricular myocardial systolic function improvement, and it is provided the clinical to evaluate the effect of PCI surgery more accurate quantitative indicators. Methods: The heart patients of our hospital with a total of 50 patients with myocardial infarction since 2011, aged 40 to 70 years old, and successfully implement PCI treatment, were randomly divided into two groups: PCI preoperative room wall segment is defined as the preoperative group, postoperative ventricular wall segment after 5 days is defined as the postoperative group. 50 cases of our hospital outpatient patients are as the control group. Both groups in the PCI preoperative 1 ~ 3 days, PCI postoperative five days and the control line echocardiography respectively. Results: In the PCI preoperative 1-3 days and PCI postoperative application of 5 days 2D-STI of abnormal segmental left ventricular wall of PSS, PSSR, RS and CS, and combined with myocardial acoustic imaging before PCI, the results of the electrocardiogram and myocardial enzymologist to the quantitative analysis of myocardial perfusion, the results showed that the PSS, PSSR of perfusion improved segmental radial and tangential strain were significantly improved, the infusion does not improve segment, there are no changes in the index. Conclusion: 2D- STI technology is from the Angle of restriction, can real-time tracking trajectories of myocardial at any location, and more accurate measurements, the application of 2D-STI technology is to provide the clinical to evaluate the effect of PCI surgery more accurate quantitative indicators, and it is with broad clinical application value.
