简介
Background
Little is known about the association between Btype natriuretic peptide (BNP) levels and catheter ablation of atrial fibrillation (AF) in patients with heart failure. This study aimed to examine the impact of elimination of AF by catheter ablation on BNP levels in patients with left ventricular systolic dysfunction.
Methods
Fiftyfour AF patients with left ventricular ejection fraction (LVEF) ≤ 50%, who underwent radiofrequency catheter ablation therapy of AF, were included. BNP sampling was performed at baseline, 3 days, and 1 month after ablation.
Results
After a followup period of 6 months, the BNP levels decreased significantly in the nonrecurrence group (n = 35; median 126.3 [interquartile 57.2–206.5] pg/mL, 63.5 [23.9–180.2] pg/mL, and 45.9 [21.9–160.3] pg/mL, P < 0.001, respectively), but not in the recurrence group (n = 19; 144.7 [87.1–217.3] pg/mL, 88.8 [12.9–213.2] pg/mL, and 118.5 [51.6–298.2 …
