Effect of Combining Ivabradine and beta-Blockers: Focus on the Use of Carvedilol in the SHIFT Population

• Objectives: We explored the prescription of beta-blockers with ivabradine in patients with systolic heart failure, focusing on the most frequently coprescribed beta-blocker, carvedilol. Methods: We analyzed outcomes in SHIFT patients with systolic heart failure who were prescribed beta-blockers (carvedilol, bisoprolol, metoprolol, or nebivolol) with ivabradine or placebo. Analysis was by intention to treat in patients prescribed a beta-blocker at the time of the event. Results: Data were available for 2,596 patients receiving carvedilol, 1,483 bisoprolol, 1,424 metoprolol, and 197 nebivolol. Mean treatment duration was 19 months. There was no difference in the effect of ivabradine on the primary composite endpoint of cardiovascular death or heart failure hospitalization between the various beta-blockers [hazard ratios (HR) for risk reduction, 0.75-0.89; p for interaction = 0.86]. Patients prescribed carvedilol with ivabradine had lower rates of primary composite endpoint (HR 0.80, 95% CI: 0.68-0.94), heart failure hospitalization (HR 0.73, 95% CI: 0.61-0.88), and cardiovascular hospitalization (HR 0.80, 95% CI: 0.69-0.92) versus carvedilol with placebo. The dosage of carvedilol had no detectable effect and there were no unexpected safety issues. Conclusions: Whatever beta-blocker was coprescribed with ivabradine, there were improvements in cardiovascular outcomes in patients with systolic heart failure, especially with the most prescribed beta-blocker - carvedilol.
