Figure 3 Effect of CRT on LVESVi
An analysis of the mean change in LVESVi (ml/m2) from baseline to 12 months is shown. The difference (CRT-OFF – CRT-ON) in the mean changes, along with its 95% confidence interval, is shown for each subgroup. Confidence intervals that do not include 0 indicate statistical significance (p < 0.05). The subgroups of age, systolic blood pressure, ejection fraction, end-systolic volume index, QRS width, interventricular mechanical delay, and glomerular filtration rate are divided according to the median value in the study sample. Green bars = CRT-ON; red bars = CRT-OFF. ICD = implantable cardioverter-defibrillator; IVMD = interventricular mechanical delay; NYHA = New York Heart Association; other abbreviations as in Figure 2.
