Figure 4 Long-Term Mortality and Hospitalizations According to Degree of Post-CABG DYS and Myocardial Viability

Kaplan-Meier estimates of the time to death from any cause or hospitalization for worsening heart failure between day 31 after CABG to the end of the follow-up period in patients without post-CABG dyssynchrony (<72 ms) and with large area (5 segments) of viable myocardium (blue solid line), patients without post-CABG dyssynchrony (<72 ms) and with small area (<5 segments) of viable myocardium (green dotted line), patients with significant post-CABG dyssynchrony (72 ms) and large area (5 segments) of viable myocardium (red solid line), and patients with significant post-CABG dyssynchrony (72 ms) and small area (<5 segments) of viable myocardium (orange dashed line). Pairwise comparison between groups is shown in accompanying table. CABG = coronary artery bypass grafting; DYS = dyssynchrony.
