New findings: Ivabradine reduces mortality and other major outcomes in chronic systolic heart failure: analysis in high risk patients with HR ≥ 75 bpm Systolic Heart failure treatment with the I f inhibitor ivabradine Trial Presentation at Rapid Fire Session, Sunday 20 May 2012
22
Rationale SHIFT and other heart failure studies showed a continuous increase in risk with increasing heart rate 64% of the patients enrolled in SHIFT had a heart rate ≥ 75 bpm A cut-off of ≥75 bpm was chosen by the EMA for the approval of ivabradine in chronic heart failure

39
Conclusion The results of new analysis are consistent with the main results of SHIFT, demonstrating that HR reduction with ivabradine prevents adverse CV outcomes In patients with HR ≥75 bpm, ivabradine significantly reduces all major outcomes, including all-cause death and CV death The magnitude of the effect is similar in patients taking or not aldosterone antagonists The magnitude of HR reduction with ivabradine, not the dose of beta-blockers, determines improvement of outcome
