1. Associations between β-blocker dosage group, predischarge heart rate group, and the primary composite outcome of death or cardiovascular rehospitalisation.
Associations between β-blocker dosage group, predischarge heart rate group, and the primary composite outcome of death or cardiovascular rehospitalisation. A and B show unadjusted Kaplan-Meier event-free survival estimates for those prescribed ≥50% vs <50% of the target dose of β-blocker, in those with reduced and preserved LVEF, respectively. C and D show unadjusted Kaplan-Meier event-free survival estimates for those whose predischarge heart rate was ≥70 vs <70/min, in those with reduced and preserved LVEF, respectively. HR: Cox HR. AF, atrial fibrillation; CHF, congestive heart failure; LVEF, left ventricular ejection fraction.
