Assessment of Left Ventricular Myocardial Function in Patients With Acute Myocardial Infarction Before and After PCI by 2D-STI
摘要
Abstract
Objective To investigate the clinical application value of 2-dimensional speckle tracking imaging(2D-STI)in the assessment of left ventricular myocardial function in patients with acute extensive anterior myocardial infarction before and after percutaneous coronary intervention( PCI). Methods We enrolled 25 patients with acute extensive anterior myocardial infarction who received PCI therapy in the Department of Cardiology in the First Affiliated Hospital of Jiamusi University from December 2012 to December 2013 as the case group. And 30 health workers and relatives of patients were enrolled as the control group. Two-dimensional ultrasonography testing was conducted on the control group and the case group before PCI and 1 week, 4 weeks and 12 weeks after PCI. The two groups were compared by the changes and differences of longitudinal strain( LS), radial strain ( RS ) and circumferential strain ( CS ) during the systolic period in different segments of myocardial muscle. Results The strain-time curves of the case group were in disorder,while those of the control group were averagely distributed. For the case group,the peak values of LS,RS and CS were no difference(P>0. 05)between week 1 and before PCI. For the case group,the peak values of LS,RS and CS at week 4 and week 12 after surgery were higher(P<0. 05)than those before PCI and at week 1;the peak values of LS,RS and CS at week 12 after PCI were higher(P<0. 05)than those at week 4 after PCI. Conclusion The 2D-STI can be used to assess myocardial function of left ventricular in patients with acute extensive anterior myocardial infarction before and after PCI and can also be taken as the reference index for the assessment of the efficacy of PCI.关键词
