Abstract:
Objective To detect viable myocardium in patients with old myocardial infarction(OMI) by using quantitative tissue velocity imaging(QTVI) in low dose dobutamine stress test(LDDSE).Methods(Twenty-five) patients with OMI were accepted QTVI examination including 2-chamber,4-chamber apical view.QTVI indices included peak velocity in isovolumic contraction(V_(IVC)),peak velocity in systolic(V_S) and time of isovolumic contraction(T_(IVC)).Results Two hundred segments were divided into the normal(group N,72 segments),viable myocardium(group V,77 segments) and non-viable myocardium(group NV,51 segments).At baseline,compared with group N,V_(IVC),V_S of group V and group NV decreased significantly(P
