Sepsis induces both a systolic and diastolic cardiac dysfunction. The prevalence of this septic cardiomyopathy ranges between 30 and 60% according to the timing of assessment and definition used. Although the prognostic role of septic cardiomyopathy remains debated, sepsis-induced left ventricular (LV) systolic dysfunction may be severe and associated with tissue hypoperfusion, while it appears to fully recover in survivors. Accordingly, optimization of therapeutic management of septic cardiomyopathy may contribute to improve tissue hypoperfusion in increasing oxygen delivery, and to reduce related organ dysfunctions in septic shock patients.
Echocardiography is currently the recommended first-line modality to assess patients with acute circulatory failure.
Current Surviving Sepsis Campaign strongly recommends Norepinephrine as the first-choice vasopressor in fluid-filled patients with septic shock. In contrast, the use of Dobutamine is only suggested (weak recommendation, low quality of evidence) in patients with persistent tissue hypoperfusion despite adequate fluid resuscitation and vasopressor support. Levosimendan, an alternative inodilator, has failed preventing acute organ dysfunction in septic patients and has induced more supraventricular tachyarrhythmias than in the control group. Data supporting Dobutamine in this setting are scarce and primarily physiologic and based on monitored effects of this drug on hemodynamics and indices of tissue perfusion.
No randomized controlled trials have yet compared the effects of Dobutamine versus placebo on clinical outcomes. In open-labelled, small sample trials, the ability of septic patients to increase their oxygen delivery during Dobutamine administration appears to be associated with lower mortality.
The tested hypothesis in the ADAPT trial is that Dobutamine will reduce tissue hypoperfusion and associated organ dysfunctions in patients with septic shock and associated septic cardiomyopathy. In doing so, it may participate in improving clinical outcomes.
