Özet

Objective: Direct current electrical cardioversion (DCCV) is an effective rhythm-control option for patients with atrial fibrillation (AF). Despite initial success, a high recurrence rate remains a significant challenge. There is limited data on the genetic predictors of AF recurrence following successful DCCV. In this study, we aimed to evaluate whether 11 single nucleotide polymorphisms (SNPs) previously associated with AF are also linked to recurrence after DCCV in the Turkish population. Methods: Seventy-five patients with persistent AF, who achieved stable sinus rhythm following DCCV, were included in the study. The patients were prospectively monitored for the onset of AF recurrence. Clinical characteristics and SNPs were analyzed and compared between patients who experienced recurrence and those who did not. Results: The average age of the patients was 61.9 ± 11.5, and 33 (44%) were female. Over an average follow-up period of 17.0 (11.0-25.0) months, AF recurrence was observed in 38 patients (50.7%). A SNP in the PITX2 gene (rs17570669) (OR: 9.00, 95% Confidence Interval (CI): 1.28-63.02) and another in the ZFHX3 gene (rs2106261) (OR: 8.96, 95% CI: 1.03-77.66) were notably associated with AF recurrence in the additive model (P = 0.027 and 0.047, respectively). Multivariate Cox regression analysis revealed that the rs17570669 SNP was the sole independent predictor of AF recurrence (Hazard Ratio (HR): 3.59, 95% CI: 1.05-12.21, P = 0.040). Conclusion: The SNP in the paired-like homeodomain 2 (PITX2) gene (rs17570669) emerges as an independent predictor for AF recurrence after successful electrical cardioversion.
