Speckle tracking-derived myocardial strain may be useful in diagnosing rare variants of stress cardiomyopathy, such as the inverted variant, following cardiac arrest.
May aid differentiation of rare stress cardiomyopathy variants post-arrest; leaves open routine diagnostic role pending prospective validation.
In cardiac arrest survivors, postresuscitation myocardial stunning usually presents as either global left ventricular dysfunction or regional dyssynergy including the various forms of stress cardiomyopathy, in which rare variants may be difficult to diagnose. We present a patient with cardiac arrest during general anesthesia, in whom speckle tracking-derived myocardial strain helped to distinguish between the inverted variant of stress cardiomyopathy and global postresuscitation myocardial stunning.
