Overview
Myocardial stunning during chronic intermittent hemodialysis is a well-described phenomenon. Little case series of patients presenting myocardial stunning during renal replacement therapy for acute kidney injury in critically ill patients are reported, with intermittent hemodialysis and continuous renal replacement therapy. However, the small sample sizes and the absence of a control arm limit their interpretation, mainly whether the myocardial stunning may be related to cardiac loading conditions variations and whether it may impact the hemodynamic.
The investigator hypothesize that myocardial stunning induced by renal replacement therapy is frequent, independent from cardiac loading conditions and associated with peripheral hypoperfusion.
