NT-proBNP as predictor of recurrence after atrial fibrillation ablation. Atrial fibrillation recurrence-free survival after ablation, stratified by baseline NT-proBNP ≥ 280 pg/mL and < 280 pg/mL. Top left: among the overall cohort (n = 173), there was no difference in recurrence between the groups (for NT-proBNP ≥ 280 pg/mL, HR 1.40, 95%CI 0.92–2.12, p = 0.10). Top right: among patients (n = 85) undergoing standard blood pressure management, < 140/90 mmHg, there was no difference (for NT-proBNP ≥ 280 pg/mL, HR 1.00, 95%CI 0.55–1.83, p = 0.998). Bottom: among patients (n = 88) undergoing aggressive blood pressure management, < 120/80 mmHg, those with baseline NT-proBNP ≥ 280 pg/mL had increased recurrence (HR 1.98, 95%CI 1.13–3.51, p = 0.02)
