Background: We have reported that cardiac
sympathetic denervation was related to the presence of T-wave alternans (TWA)
in patients with non-ischemic heart disease (NIHD) in the previous ACC
meeting. Recently, it has been observed that mechanical alternans disappeared
with the improvement of left ventricular ejection fraction (EF) with
ß-blocker therapy in patients with DCM. The aim of this study was to
investigate whether TWA findings also improve together with the improvement
of cardiac sympathetic denervation and EF with ß-blocker in positive TWA
patients with NIHD. |
