The recurrence rate of atrial fibrillation (AF) after bipolar radiofrequency ablation was about 30%. Besides the factors, left atrium diameter, the duration of AF, NT-proBNP, and ejection fraction(EF), some studies demonstrated that the specific microRNA expression (miRNA1, miRNA19,miRNA23, miRNA409 ) showed the significant change in AF patients compared with normal sinus patients, who underwent catheter ablation. Therefore, the correlation of atrial fibrillation recurrence and above-mentioned microRNA after bipolar radiofrequency ablation remained unclear, although bipolar radiofrequency ablation had high rate of sinus.
Numerous studies identify specific microRNA (miRNA) expression profiles associated with atrial fibrillation (AF), changes in plasmamiRNA expression in pre-and post-operativeAFpatients who have received catheterisation . The correlation of atrial fibrillation recurrence and above-mentioned microRNA after bipolar radiofrequency ablation remain poorly characterized.
This study aimed to reveal disease-related biomarkers by detecting plasmamiRNA expression in AF patients, and examining the levels of AF-specific miRNAs in patients after bipolar radiofrequency ablation, in order to help gauge therapeutic effects and assess prognosis.
A total of 50 Han Chinese patients with AF who had received bipolar radiofrequency ablation recruited to the study. Atrial fibrillation-specific plasma miRNAs were detected by sequencing and quantitative reverse transcription polymerase chain reaction. According to AF recurrence rate of about 30%, the expression levels of AF-specific miRNAs were investigated in15 post-operative AF patients and 35 patients with normal sinus after ablation,to explore changes in miRNA expression.
