Study summary

Cardiogenic shock is a frequent cause of admission and death in the intensive care unit.

Mortality is about 50%. Once the etiologic treatment has been done, for instance coronary revascularization, management of the shock state is the cornerstone of the treatment. Norepinephrine is the first-line vasopressor therapy because of its minor effect on heart rhythm. Morever norepinephrine is a inotrope. In a previous study, we demonstrated that increasing the norepinephrine dose increases cardiac index, cardiac power index, SVO2 and tissue perfusion without acceleration of heart rate. Nevertheless, dobutamine remains the first-line inotropic treatment. Dobutamine has a positive chronotropic effect that might cause higher myocardial oxygen consumption. As a result, combination of vasopressor / inotrope is still controversial.

The aim of this study was to compare hemodynamics and metabolics effects of 2 treatments strategies (norepinephrine dose increasing or addition of dobutamine) in patients with cardiogenic shock and optimised blood pressure level (MAP≥65 mmHg) under norepinephrine treatment.

The secondary objectives were :

  • To evaluate the efficacy of the treatments on micro- and macrocirculation parameters
  • To evaluate the tolerance of the treatments
  • To evaluate the dose and the admistration's kinetics of the treatments

Study arms

  • Experimental
    Norepinephrine alone

    Administration of norepinephrine with increasing dose

    Drug: Norepinephrine

  • Active comparator
    Norepinephrine plus Dobutamine

    Administration of norepinephrine and dobutamine

    Drug: Norepinephrine

Interventions

  • After obtention of a mean arterial pressure (MAP) of 65 mmHg with infusion of norepinephrine, patients with cardiogenic shock receive for 3 hours either increasing doses of norepinephrine (with a maximal MAP of 85 mmHg) or dobutamine. There is a wash-out phase of 30 minutes (decrease of norepinephrine dose or weaning of dobutamine). The third phase of the study is the administration of the comparator treatment during 3 hours. After the 6.5 hours of the study, the hemodynamic management is up to the physician.

    Also known as: Dobutamine

What researchers measure

Primary outcomes

  1. Obtention of a optimal cardiac output

    Measure of increase of cardiac index \> 15% (L/min/m²), increase of organ perfusion assessed by : lactate clearance \> 15% (mmoL/L), decrease of mottling (decrease of 2 points of Mottling score), increase of musculaire oxygen saturation measured by NIRS \> 15% (rSo2%), increase of urine output \> 50% (mL/h), increase of SVcO2 \> 15%(%) Evaluation of occurence of side effects : Increase of heart rate \> 15% (bpm) , increase of oxygen consumption evaluated by decrease of ratio mean arterial pressure / heart rate \> 15% (Buffington ratio). The primary endpoint is defined by the presence of 2 efficacy criterias without any side effects.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Nov 14, 2017, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
