The Evaluation Of Left Ventricular Remodeling And Effectiveness After Percutaneous Coronary Intervention Using Rt-3de In Patients With Acute Myocardial Infarction

Objective:(1)To assess regional left ventricular systolic function and wall motion synchronismin patients with acute myocardial infarction using real-time three-dimensionalechocardiography;(2)Evaluate left ventricular remodeling and effectiveness in patientswith acute myocardial infarction after percutaneous coronary intervention.Methods:63 patients with acute myocardial infarction were enrolled in this study. Real-timethree-dimensional echocardiography(RT3DE) and two dimensional echocardiography(2DE) was performed.(1) regional end diastolic volume(r EDV), regional end systolic volume(r ESV),regional ejection fraction(r EF), wall motion synchronism were analyzed offline withRT-3DE Qlab(8.1)software. Compare the changes of each parameter of the infarctionrelated segment among 1 weeks post-PCI, 3 months post-PCI and 6 months post-PCIoperation.(2) The end diastolic volume(EDV),end systolic volume(ESV),left ventricularejection fraction(EF) measured by 2DE and RT-3DE, and compare the differences of EDV,ESV, EF measured by 2DE and RT-3DE.(3) The patients were divided into improvement group and no improvement group,compare wall motion synchronism between the two group.(4) To evaluate the prognosis of the patients with acute myocardial infarction byeffectiveness of PCI and the change of above parameters.Results:(1) Left ventricular remodeling could be found in patients with AMI.RT3 DE could bea new valuable method of evaluating the change in patients with AMI post-PCI.(2) Interventional theraphy can reverse left ventricular remodeling.(3) The value of left ventricular function of patients with acute myocardial infarctionmeasured by 3DE are more accurately than 2D.(4) Tmsvl6-SD% and Tmsv6-Dif% could be new valuable parameters of evaluatingthe effectiveness of patients with acute myocardial infarction.
