  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
