Figure 2  .

Individual values of per cent wall thickening (%WT) (A) and magnitude of cardiac cycle dependent variation of integrated backscatter of the myocardium (CVIB) (B) for segments with contractile reserve (CR+) and those without (CR−). There was a weak but significant difference in %WT at rest between segments with and without contractile reserve. The magnitude of CVIB was significantly greater in segments with contractile reserve that in those without.
