Abstract
<p>Aims: To test the effect of ivabradine on the outcomes in a broad population with left-ventricular (LV) systolic dysfunction with coronary artery disease (CAD) and/or heart failure (HF).</p> <p>Methods and results: Individual trial data from BEAUTIFUL and SHIFT were pooled to evaluate the effect of ivabradine on the outcomes in patients with LV dysfunction and heart rate ≥70 b.p.m. The pooled population (n = 11 897; baseline age 62.3 ± 10.4 years, heart rate 79.6 ± 9.2 b.p.m., and LV ejection fraction 30.3 ± 5.6%) was well treated according to current recommendations (87% beta-blockers, 90% renin–angiotensin system inhibitors). Median follow-up was 21 months. Treatment with ivabradine was associated with a 13% relative risk reduction for the composite of cardiovascular mortality or HF hospitalization (P < 0.001 vs. placebo); this was driven by HF hospitalizations (19%, P < 0.001). There were also significant relative risk reductions for the composite of cardiovascular mortality, HF hospitalizations, or myocardial infarction (MI) hospitalization (15%, P < 0.001); cardiovascular mortality and non-fatal MI (10%, P = 0.023); and MI hospitalization (23%, P = 0.009). Similar results were found in patients with differing clinical profiles. Ivabradine was well tolerated.</p> <p>Conclusion: Ivabradine may be important for the improvement of clinical outcomes in patients with LV systolic dysfunction and heart rate ≥70 b.p.m., whatever the primary clinical presentation (CAD or HF) or clinical status (NYHA class).</p>
