What this trial studies

This clinical trial investigates the effectiveness of inotropes, specifically Dobutamine and Milrinone, compared to a placebo in critically ill patients experiencing cardiogenic shock. Conducted as a multi-centre, double-blind, randomized control trial, it aims to determine if these medications can improve heart function and patient outcomes. Participants will be closely monitored, and medication dosages will be adjusted based on their clinical status. After 12 hours, treatment will transition to open label, allowing physicians to decide on continued inotrope use.

Who should consider this trial

Good fit: Ideal candidates include adult patients aged 18 and older who are admitted to an intensive care unit with SCAI class C or D cardiogenic shock.

Not a fit: Patients who are pregnant, have severe valvular lesions, or have recently received inotropes may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide evidence for the safe and effective use of inotropes in treating cardiogenic shock, potentially improving patient survival and recovery.

How similar studies have performed: Previous studies have shown mixed results regarding the use of inotropes in cardiogenic shock, indicating that while some evidence exists for their use, the certainty of benefit remains low.
