Study Details

Brief summary:

This is a randomized, double blind, single center trial to study of the effects of Ivabradine vs. Placebo on patients hospitalized for Stage D heart failure (HF)/ and cardiogenic shock (CS) who will require continuous infusion of Dobutamine and have developed sinus tachycardia (ST) (heart rate >100 beats/min).

The aim of the study will be to assess the potential of Ivabradine to slow ST and improve hemodynamics in patients with stage D HF/CS on Dobutamine treatment.
