  Fig. 1. Recommended algorithm for patients who are normal and rapid CYP metabolisers. *Interrupt treatment at any point if LVEF <50%

• 

  Fig. 2. Recommended algorithm for patients who are slow/poor CYP metabolisers or while CYP status is pending. *Interrupt treatment at any point if LVEF <50%

• 

  Fig. 3. Maintenance assessment algorithm. Echocardiography should be performed every 24 weeks unless a dose titration is needed or LVEF drops to < 50%

• 

  Fig. 4. Actions if LVEF drops to < 50%. If at any visit the patient’s LVEF is < 50%, the treatment should be interrupted for at least 4 weeks and only restarted if LVEF ≥ 50%
