title: [Usefulness of treatment evaluation of severe heart failure by ECG-gated myocardial SPECT].
abstract: Our purpose of study was to investigate the usefulness of treatment evaluation of severe heart failure by ECG-gated myocardial SPECT. We evaluated the cardiac function in the case of severe heart failure by gated SPECT and compared it with the cardiac function obtained by LVG, echocardiography, cardiac MRI, and BNP values. We investigated the correlation of EF, time lag of wall motion between the septal and lateral walls of the left ventricle for CRT and wall thickening (WT). We classified the LV into basal, middle and apical areas for comparison of WT. We investigated the effect of a perfusion defect score in these comparisons. The gated SPECT results were correlated with comparative subjects in EF. The results were correlated with MRI on the middle area of the LV in the comparison of WT. We thought it was possible that there was an effect from a perfusion defect score in a time lag comparison of wall motion. Treatment evaluation of severe heart failure by gated SPECT is useful, because it is able to obtain three-dimensional cardiac function analysis, and it offers objectivity and reproducible quantitative evaluation. At the same time, perfusion SPECT is helpful for CRT and LV-plasty.
