Atrial structural remodeling in atrial fibrillation is characterized histologically by fibrosis, increased intercellular space, myofibrillar loss, and decreased nuclear density.
Histological correlates of atrial structural remodelling were fibrosis, increased intercellular space, myofibrillar loss, and decreased nuclear density. Each histological component was defined using electron microscopy and immunohistochemistry studies.
Takahashi et al. (Fri,) studied this question.
