Echocardiograms were performed 12 months post-BMT. Similar numbers of fully chimeric male and female mice were used in the experimental groups. Data are presented as mean plus or minus SEM. Statistical significance was determined using 1-way ANOVA followed by the Tukey's multiple comparison test.
bpm, beats per minute; LW E′, lateral wall mitral valve tissue Doppler E wave; MV E, mitral valve early filling.
