Objective: This study aimed to analyze the clinical significance of body mass index (BMI), mean platelet volume (MPV), and left atrial structure in the recurrence of atrial fibrillation (AF) after treatment with catheter radiofrequency ablation.
Methods: A total of 69 patients with AF who underwent catheter radiofrequency ablation at Beijing Anzhen Hospital from January 2020 to July 2021 (research group) were compared to 75 patients who underwent physical examination during the same period (control group). MPV levels were measured before and after treatment in both groups. Additionally, height and weight measurements were used to calculate BMI, while left atrial anteroposterior diameter, left atrial volume, and left atrial volume index were recorded using cardiac ultrasonography.
Results: The research group exhibited higher BMI, MPV, left atrial anteroposterior diameter, left atrial volume, and left atrial volume index compared to the control group, and these parameters decreased after treatment (P < .05). Prognostic follow-up revealed that patients with AF recurrence had higher values for these parameters than those without recurrence (P < .05). Receiver Operating Characteristic analysis indicated that all these parameters had good predictive value for prognostic recurrence of AF (P < .05). Logistic regression analysis demonstrated that all the parameters were independent risk factors for prognostic atrial fibrillation recurrence (P < .05).
Conclusions: BMI, MPV, and left atrial structure are associated with the occurrence and development of atrial fibrillation. These parameters provide an excellent assessment of the prognosis for AF recurrence after catheter radiofrequency ablation treatment. Monitoring changes in BMI, MPV, and left atrial structure in atrial fibrillation patients can contribute to more reliable prognostic information in clinical settings.
