Objectives
Renal dysfunction determined with GFR, has been reported to be associated with a higher atrial fibrillation (AF) recurrence rate following catheter ablation for AF. Beta-trace protein (BTP) is a novel biomarker of renal function. Our aim in this study is to evaluate the association between serum BTP levels and outcome following ablation for paroxysmal AF.
Methods
120 patients (53.8± 7.7 years, 58.3% male) who underwent pulmonary vein isolation (PVI) with cryoballoon for paroxysmal AF were included in the study. All subjects had relatively normal renal function (estimated glomerular filtration rate [eGFR] >60 ml/min per 1.73 m2). Serum BTP levels were measured by ELISA and compared between two groups.
