Experimental
Placebo Comparator
Ivabradine
Placebo
Ivabradine will be administered in an individualized regimen adapted to the subject's heart rate at each visit in a dosage ranging from 0-7.5mg twice daily (morning and evening) from the morning of surgery until post-operative day 2, as follows: If heart rate is ≥101 bpm: capsule D (Ivabradine 7.5 mg); If heart rate is 86-100 bpm: capsule C (Ivabradine 5 mg); If HR is 71-85 bpm: capsule B (Ivabradine 2.5 mg); If HR ≤ 70 bpm or the patient received rescue treatment for bradycardia (eg.atropine) after the previous dose: capsule A (placebo).
Placebo will be administered twice daily (morning and evening) from the morning of surgery until post-operative day 2, as follows: If heart rate is ≥101 bpm: capsule D (Placebo) If heart rate is 86-100 bpm: capsule C (Placebo) If HR is 71-85 bpm: capsule B (Placebo) If HR ≤ 70 bpm or the patient received rescue treatment for bradycardia (eg.atropine) after the previous dose: capsule A (Placebo).
