Rate and Kaplan Meier Curves of PVC-Cardiomyopathy. (A) Rate of PVC-Cardiomyopathy in the overall population based on different treatment groups (amiodarone vs placebo groups) at 6 months. PVC-Cardiomyopathy defined as LV-recovery (LVEF improvement ≥10%) on only those with successful PVC suppression (≥80% PVC reduction). No LV-recovery (LVEF improvement <10%) despite successful PVC suppression represents cardiomyopathy unrelated to PVCs. LV recovery despite lack of PVC suppression represents a reversible CM unrelated to PVCs. Comparison of Event free survival between subjects with PVC-Cardiomyopathy (PVC suppression >80% and LVEF increase >10%) vs. non-PVC-Cardiomyopathy (PVC suppression <80% with or without LV recovery and PVC suppression >80% without LV recovery) in overall (B) and non-ischemic (C) population regardless of treatment randomization. PVC-CM, PVC-Cardiomyopathy.
