Silent myocardial ischemia: prognostic significance and therapeutic implications.

abstract：BACKGROUND:When used in appropriately selected heart failure (HF) patients, cardiac resynchronization therapy (CRT) reduces mortality and hospitalization. It is not understood whether CRT implantation during hospitalization for HF is associated with similar benefits. HYPOTHESIS:Timing of CRT implantation relative to h...
