Conclusions
 In HF in sinus rhythm with HR ≥75 bpm heart rate reduction
with ivabradine improves outcomes, including all-cause
death and cardiovascular death reduces
 Ivabradine-associated risk reductions are related to both
HR achieved and magnitude of HR reduction
 Patients achieving <60 bpm or with >10 bpm reduction
have the best prognosis
