Excerpt
Here we review the publication by Tournoux et al in the European Heart Journal-Cardiovascular Imaging from the November issue of 2015.
1 The aim of this retrospective study was to evaluate the predictive utility of mechanical dyssynchrony as measured by equilibrium radionuclide angiography (ERNA) for hard cardiovascular outcomes in patients undergoing cardiac resynchronization therapy (CRT). The study evaluated 146 ERNA studies and found that survival in patients without mechanical dyssynchrony on ERNA did not differ between patients receiving CRT and those not receiving CRT (
P = .34). Patients with a high level of dyssynchrony had worse outcomes than patients without (
P = .004). Further the presence of mechanical dyssynchrony was associated with better outcomes after CRT than without (
P = .004). …
