Abstract:

Objective To investigate the relationship between left ventricular hypertrophy (LVH) diagnosed by Peguero-Lo-Presti index and recurrence of paroxysmal atrial fibrillation (AF) after radiofrequency ablation. Methods A total of 652 patients with paroxysmal atrial fibrillation who underwent radiofrequency ablation were selected. According to Peguero-Lo-Presti index, patients were divided into the LVH group (167 cases) and the normal left ventricle group (485 cases). Baseline data were collected, and regular follow-up was performed at 3, 6 and 12 months after radiofrequency catheter ablation. The recurrence of AF was assessed. Kaplan-Meier survival curve was used to analyze the recurrence rate of AF in the two groups. Cox proportional hazard model was used to assess risk factors for recurrent atrial fibrillation. Results The median follow-up time was 20.5 (15.0, 26.0) months. A total of 155 patients (23.8%) developed recurrence of AF, including 95 patients in the LVH group and 60 patients in the LVN group. The recurrence rate without AF was significantly lower in the LVH group than that in the LVN group (64.1% vs. 80.4%, Log-rank χ2=26.361, P<0.01). After adjusting for age, sex, body mass index, hypertension, diabetes, coronary heart disease, cardiac dysfunction, left anteroposterior and posterior atrial diameter, left ventricular end-diastolic diameter, and left ventricular ejection fraction, LVH diagnosed by Peguero-Lo-Presti index was still a risk factor for recurrent AF [HR (95%CI) : 2.359 (1.663-3.345), P<0.01]. Conclusion In patients with paroxysmal AF, LVH diagnosed by Peguero-Lo-Presti index is a risk factor of AF recurrence after radiofrequency catheter ablation.
