Background:
Catheter ablation for atrial fibrillation (AF) has been gaining popularity; however, the trend of inflammatory response markers in patients treated with different catheter ablation strategies over time and their predictability of AF recurrence remain unknown.
Methods:
A total of 210 patients with AF were enrolled and grouped according to surgical mode as follows: freeze group, RF group, and freeze3D group. The subjects were tested for related indexes before and after surgery. To determine AF recurrence during follow up, 24-h ambulatory electrocardiography was performed at two, three, six, and 12 months after surgery.
Results:
The inflammation indexes of the three groups peaked between one and three days after surgery but fell at different time points (P < .05). The recurrence rate of paroxysmal atrial fibrillation (PAF) was positively correlated with the increase in the percentage of white blood cells and neutrophils after surgery (P < .05).
Conclusions:
The postoperative inflammation indices peaked and fell at different time points after different catheter ablation methods. In addition, the recurrence rate of AF in patients treated with freeze3D is lower.
