Composite of cardiovascular death or hospitalisation for worsening heart failure

Relevancia

Resultado24% with ivabradine vs 29% with placebo (HR 0.82, 95% CI 0.75-0.90; P<0.0001), driven mainly by fewer HF hospitalisations.

Discusión y crítica

Benefit confined to sinus rhythm with heart rate ≥70 bpm, and background beta-blocker doses often submaximal. Established ivabradine for HFrEF with elevated heart rate despite maximally tolerated beta-blockade.
