OBJECTIVE: To investigate whether atrial expression of interleukin-1beta (IL-1beta) and tumor necrosis factor-alpha (TNF-alpha) of right atrial appendages are altered in patients with rheumatic valvular disease during chronic atrial fibrillation.
METHODS: A total of 48 patients with rheumatic heart disease were included. 27 patients had no history of atrial fibrillation, 21 patients had atrial fibrillation. Atrial tissue was obtained from the right atrial appendage during open heart surgery. The protein expression of IL-1beta and TNF-alpha was detected by immunohistochemistry method. The fibrosis of right atrial appendage was detected by Masson staining.
RESULTS: The fibrosis of right atrial appendage was significantly increased in patients with chronic atrial fibrillation. The protein expression of IL-1beta and TNF-alpha were significantly increased in patients with chronic atrial fibrillation.
CONCLUSIONS: The protein expression of IL-1beta and TNF-alpha were significantly increased in patients with rheumatic valvular disease during chronic atrial fibrillation. Inflammation may be one of the mechanisms for the development and persistence of atrial fibrillation.
