Normalization of LV structure and function was accompanied by partial normalization (~60%) of gene expression associated with incident HF. Similar findings were observed in patients with dilated cardiomyopathy who underwent reverse LV remodeling following mechanical circulatory support. Persistence of the HF gene program was associated with an exaggerated hypertrophic response and increased mortality in tTA-TRAF2\n                    <jats:sup>dox4W<\/jats:sup>\n                    mice following transaortic constriction (TAC). These effects were no longer observed following TAC in tTA-TRAF2\n                    <jats:sup>dox8W<\/jats:sup>\n                    , wherein there was a more complete (88%) reversal of the incident HF genes. These results demonstrate that reverse LV remodeling is associated with improvements in cardiac myocyte biology; however, the persistence of the abnormal HF gene program may be maladaptive following perturbations in hemodynamic loading conditions.\n
