Calcium cycling gene expression. Cardiac resynchronization patients before (1 mo) and after (5 mo) period of study (A and B). Exercise (ET) and untrained (NoET) periods quantified as changes in expression of the Na/Ca2+ exchanger (NCX, C) and ryanodine (D). *Note that the change in expression of the NCX was significantly greater in the ET group. In addition, the expression of ryanodine, in contrast to NoET group, was preserved in the ET group.
