Abstract：Objective To explore the application value of electrocardiogram P-wave parameters combined with body mass index(BMI)for predicting the recurrence of paroxysmal atrial fibrillation(PAF)patients after radiofrequency abla-tion.Methods A total of 109 patients after PAF ablation admitted to the First Affiliated Hospital of Xinjiang Medical Uni-versity from March 2021 to December 2022 were retrospectively selected as the study objects,and they were separated into a recurrence group(n=24)and a non-recurrence group(n=85)based on their postoperative recurrence within one year.109 patients with PAF underwent 12-lead electrocardiogram before and within 24 hours after surgery.Clinical data such as preoperative BMI and left atrial diameter(LAD)were collected and a multivariate Logistic regression model was applied to analyze the influencing factors of postoperative recurrence in patients with PAF.ROC curve was used to analyze the predic-tive value of P wave parameters combined with BMI in postoperative recurrence of PAF patients.Results Among 109 pa-tients with PAF,24 experienced recurrence within one year after surgery,with a recurrence rate of 22.02%.Duration of atrial fibrillation,proportion of hypertension,LAD,ratio of neutrophil/lymphocyte count(NLR)and BMI in the relapsed group were higher than those in the non-relapsed group(t/χ2/P=2.559/0.012,5.827/0.016,4.557/<0.001,5.254/<0.001,4.436/<0.001).The preoperative P-wave duration(PWD),maximum PWD(Pmax),and P-wave dispersion(Pd)in the recurrence group were greatly higher than those in the non-recurrence group(t=5.617,4.005,9.078,all P<0.001).Multivariate Logistic analysis showed that BMI,LAD,NLR,hypertension,PWD,Pmax and Pd were the risk factors for postoperative recurrence in PAF patients[OR(95%CI)=1.163(1.008-1.342),1.256(1.024-1.540),1.458(1.106-1.922),1.435(1.045-1.971),1.509(1.136-2.005),1.157(1.005-1.332),1.714(1.308-2.246)].The combined prediction of AUC in PAF patients was better than PWD,Pmax and BMI(Z/P=2.017/0.044,2.476/0.013,2.788/0.005),and compared with the AUC predicted by Pd alone,the difference was not statistically significant(Z/P=1.946/0.052).Conclusion BMI,LAD,NLR,hypertension,PWD,Pmax,and Pd are influencing factors for postoperative recurrence in patients with PAF.Preoperative PWD,Pmax,and Pd combined with BMI have high predictive value for postoperative recurrence in PAF patients.
