Relationship between valvular structure and biochemical indices of non-valvular atrial fibrillation and senile degenerative valvular heart disease.

Background: Valvular heart disease (VHD) is a common clinical condition in geriatric-related cardiovascular diseases that is connected to heart dysfunction. Atrial fibrillation (AF) is the most frequent arrhythmia. Considering these two common clinical conditions, so far no sufficient data on the relationship between degenerative VHD and non-valvular atrial fibrillation (NVAF).
