Abstract:
Objective:To investigate the value of myocardial velocity gradient(MVG) in diagnosis of myocardial ischemia.Methods:Thirty-eight patients with coronary artery disease and twenty-eight healthy volunteers were enrolled in this study,MVG-L+ in systolic stage and MVG-L-in diastolic stage were measured from apical four chamber and two chamber view.Results:In normal group,MVG-L+ and MVG-L-was slightly different among basal,middle and apical segments of left ventricular wall,which was no statistical difference.Compared with normal group,MVG-L+ and MVG-L-measured from myocardial ischemia group significantly decreased.Conclusion:MVG can quantitatively analyze the motional state of regional myocardium,alternatively providing an effective index of evaluating cardiac function in coronary artery disease.
