FIGURE 1. (A) Changes in LVEDV from baseline (white bars) to 6-mo follow-up (black bars) in responders and nonresponders to CRT. LVEDV decreased significantly in responders and remained unchanged in nonresponders. *P < 0.0001 baseline vs. 6-mo follow-up. (B) Changes in LVESV from baseline (white bars) to 6-mo follow-up (black bars) in responders and nonresponders to CRT. LVESV decreased significantly in responders and remained unchanged in nonresponders. *P < 0.0001 baseline vs. 6-mo follow-up. (C) Changes in LVEF from baseline (white bars) to 6-mo follow-up (black bars) in responders and nonresponders to CRT. LVEF increased significantly in responders and remained unchanged in nonresponders. *P < 0.0001 baseline vs. 6-mo follow-up.
