V nonresponders improved with LV pacing and 31% vice versa.Ĭlinical trials Trials Comments CRT-D CRT plus ICD showed an almost significant trend toward lower all-cause mortality compared to CRT alone in patients with NYHA III or IV Reduce risk of rehospitalization, HF events and remodeling in patients with NYHA I or II NYHA II CRT decreased mortality (OR 0. V pacing was similar (48 and 55 percent). Clinical response (≥ 20% increase in exercise duration) to LV and Bi. V pacing or vice versa for consecutive 6 m periods Reverse remodeling (≥ 15 percent reduction in LV ESV) was observed in 47% LV pacing and 55% Bi. GREATEREARTH randomized to LV followed by Bi. At 6 m, LV pacing non inferior (improvement in NYHA class, reverse remodeling, improvement in HF composite score, and reduction in LV ESV of at least 10%). V pacing had the greatest improvement in ESV) B-LEFT HF randomized to Bi. At 6 m, all groups had a significant improvement in LVEF and LV volumes (standard Bi.
