Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Data regarding the safety and efficacy of ivabradine use in severely decompensated HFrEF requiring inotropic support is limited to case series.1 This study aimed to evaluate ivabradine safety and tolerability in admitted cardiogenic shock patients who started on dobutamine infusion for inotropic support.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Background and study rationale:

Ivabradine is a Heart Rate (HR) lowering agent which acts by inhibiting the If current in the sinoatrial node. It is currently indicated in patients with chronic heart failure with reduced ejection fraction (HFrEF). Dobutamine is an inotropic drug used in cardiogenic shock patients and it is associated with an increase in HR and incidence of cardiac arrhythmias.2 However, studies have suggested that increased heart rate may be deleterious in decompensated HFrEF due to an inverted Bowditch-Treppe response. Data regarding the safety and efficacy of ivabradine use in severely decompensated HFrEF requiring inotropic support is limited to case series.1, 2
