Abstract: Objective To investigate the application of strain rate imaging in quantitative assessment of left ventricular regional diastolic function after intracoronary stent implantation.Methods Fifty-six healthy person and 60 patients with coronary artery disease were performed quantitative assessment of left ventricular regional diastolic function by apical four chamber view,apical two chamber view and left ventricular long axis view before and after intracoronary stent implantation using strain rate imaging.Results Compared with those of normal myocardium,the peaks of strain rate curve at diastole of ischemic myocardium were reduced,and were increased after operation (P ＜ 0.05).Conclusions Intracoronary stent implantation can significantly improve the blood supply to the ischemia myocardium.Strain rate imaging can quantitatively analyze the changes of left ventricular regional diastolic function.
