Cytoskeletal remodeling of desmin is a more accurate measure of cardiac dysfunction than fibrosis or myocyte hypertrophy

Desmin, fibrosis, and myocyte hypertrophy are temporally and spatially heterogeneous in HF. Desmin content more accurately correlated with remodeling than fibrosis or myocyte hypertrophy, suggesting that intra-myocyte responses, likely related to mechanical stretch, are better predictors of LV function and may represent novel targets for therapeutic intervention.
