Ejection fraction (%)55.7 ± 13.454.6 ± 9.356.9 ± 13.359.3 ± 14.3
IZWM (SD/chord)−2.41 ± 1.22−3.06 ± 0.68−2.50 ± 1.26−1.98 ± 1.59
Abnormal chords (no.)21.9 ± 17.724.9 ± 9.622.0 ± 17.717.4 ± 17.1
  • legend Data are presented as mean value ± SD. Analysis of variance determined that at least one group mean was significantly different from another group mean at the 0.05 level for IZWM and abnormal chords. Because of the unequal group sizes and variances, the Tukey posterior test was performed to discern group differences. For abnormal chords, the mean value of the lytic success group was statistically better than that of the rescue PTCA success group and the lytic failure/no PTCA group. For IZWM, the mean value of the lytic success group was statistically better than that of the lytic failure/no PTCA group. Abbreviations as in Table 3.
