Background: Smoking has been associated with an increased risk of atrial fibrillation. Arterial stiffness, a higher carotid intima-media thickness, and the presence of carotid plaque have been associated with a higher incidence of atrial fibrillation. The new second-generation cryoablation balloon catheter has been successful in the treatment of atrial fibrillation. We sought to evaluate the recurrence of atrial fibrillation in current or former smokers and never smokers after successful cryoablation using the Arctic Front Advance catheter.
Methods: This is a single center retrospective analysis of all patients with paroxysmal atrial fibrillation who underwent cryoablation using the Arctic Front Advance catheter at our medical center between September 2012 and October 2014. Patients were followed for six months for any documented episodes of atrial fibrillation (Table 1). Patients were divided into having a history of smoking and never smokers. Any patient who did not follow up for a minimum of six months was excluded. All demographics were not significantly different between both groups.
Conclusions: We found that there was a statistically significant increase in recurrent atrial fibrillation after cryoablation in patients with a history of smoking. We hypothesize that the effects of smoking on arterial walls causing intima-media thickening and stiffness may promote the recurrence of atrial fibrillation.
