EDV for HF vs. WT mice. Shaded and open symbols are the average of the nearest two time points for each animal at each time point. Note the abrupt dilatation phase in HF hearts, as well as the consistently larger chamber at all time points. Statistical significance refers to the difference in volume between the earliest and latest time points within each bracket for the entire HF data set (N = 4). HF vs. time: * P < 0.005. NS: not statistically significant.
