    To the Editor Prior et al. 1 report on survival prediction in patients with ischaemic cardiomyopathy following surgical intervention and found that end-systolic volume (ESV) index (I) is the strongest indicator of survival. Their findings are partly based on an imputation procedure which is reported to have not affected the outcomes. We have no reason to doubt this statement, but we are left with three major issues:

    1. Some inconsistencies require clarification. In figure 1, the ESVI range is limited to 150, while …
