Incidence of Complications and Related Factors after Radiofrequency Ablationin Elderly Patients with Atrial Fibrillation

Abstract

Objective To observe the incidence of complications after radiofrequency ablation in elderly patients with atrial fibrillation and explore its related influencing factors. Methods A total of 260 elderly patients with atrial fibrillation who underwent radiofrequency ablation in Shandong Provincial Hospital,Shandong First Medical University from February 2021 to February 2023 were selected as the study subjects and their data were collected.The multivariate logistic regression model was used to analyze the influencing factors of complications in elderly patients with atrial fibrillation after radiofrequency ablation. Results Complications occurred in 51 elderly patients with AF after radiofrequency ablation,with an incidence of 19.62%(51/260).The main complications included subcutaneous hematoma,local tension blister at puncture site,thromboembolism,acute cerebrovascular events,vagus reflex,etc.Multivariate logistic regression analysis found that left atrial diameter,past stroke history,patients′ perception of the tightness of compression bandage,international normalized ratio and soluble growth stimulation expressed gene 2(sST2) were independent risk factors for complications in elderly patients with AF after radiofrequency ablation(P<0.05). Conclusion There is a higher risk of complications in elderly patients with atrial fibrillation after radiofrequency ablation.Left atrial diameter,past stroke history,patients’ perception of the tightness of compression bandage,international normalized ratio and sST2 are possible influencing factors,which deserve attention.
