Table 3 Multivariable predictor predictors of post-ablation recurrence of atrial fibrillation are shown, by blood pressure treatment group, with corresponding adjusted hazard ratios

From: The role of brain natriuretic peptide in atrial fibrillation: a substudy of the Substrate Modification with Aggressive Blood Pressure Control for Atrial Fibrillation (SMAC-AF) trial

Predictor Aggressive cohort (n = 88) Standard cohort (n = 85)
HR (95% CI) p value HR (95% CI) p value
logNT-proBNP 1.43 (1.03–1.99) 0.03 0.83 (0.61–1.12) 0.22
Age 0.96 (0.92–1.01) 0.12 1.05 (1.01–1.10) 0.01
Sex 0.90 (0.40–2.00 0.79 1.08 (0.47–2.45) 0.86
SBP 1.03 (1.00–1.05) 0.045 1.01 (0.98–1.04) 0.48
LVEF 1.02 (0.98–1.06) 0.35 1.00 (0.95–1.06) 0.94
AF type 0.95 (0.48–1.88) 0.87 1.04 (0.53–2.05) 0.89
  1. Significant results (p < 0.05) are bolded
  2. All characteristics were measured at time of randomization. The aggressive cohort had a target blood pressure of < 120/80 mmHg, and the standard cohort had a target of < 140/90 mmHg
  3. AF, atrial fibrillation; SBP, systolic blood pressure; LVEF, left ventricular ejection fraction
