적응증 (①+②+③+④)

① LVEF ≤ 35 %, 
② 증상이 있는 chronic stable heart failure (HF),  
③ resting heart rate ≥70 bpm인 sinus rhythm

④ 최대 허용 용량 베타 차단제를 복용 중이거나 사용 금기 사항에 해당하는 경우 
우리는 ivabradine 치료를 제안합니다.

동시 치료는 ACEI(또는 ARB)와 mineralocorticoid receptor blocker(칼륨을 적절히 모니터링 할 수있는 경우)를 포함해야 합니다.  

우리는 70 bpm 이상의 역치를 사용하는데
이것은 HFrEF 환자의 입원 위험 감소에 있어 이바브라딘의 효능을 입증한 무작위 임상 시험의 진입 기준이었기 때문입니다.

Major society guidelines — The above recommendation for ivabradine use in stable chronic HF is similar to recommendations included in the 2016 American College of Cardiology/American Heart Association focused update on pharmacological therapy for HF and in the 2016 European Society of Cardiology HF guidelines.

금기

★ Acute decompensated HF.
★ Blood pressure less than 90/50.
★ Sick sinus syndrome, sinoatrial block or third degree atrioventricular block, unless a functioning demand pacemaker is present.
★ Pacemaker dependence (heart rate maintained exclusively by pacemaker).
★ Severe hepatic impairment.
★ In combination with strong cytochrome CYP34A inhibitors since these would increase ivabradine plasma concentrations.
