Reversible electrocardiogram changes and cardiomyopathy secondary to baclofen withdrawal syndrome.

Abstract

Baclofen withdrawal syndrome is a rare and potentially life-threatening condition manifesting with autonomic dysreflexia, high fevers, spasticity, seizures, and multiorgan failure. Reversible cardiomyopathy due to this condition is extremely rare. A high level of suspicion is needed to recognize this condition and start an early intervention to improve patient outcome. Electrocardiographic ST-segment elevation in lead aVR was previously described in association with left main, left anterior descending, and triple-vessel coronary artery disease as well as Takotsubo cardiomyopathy. In this article we present a rare case of reversible cardiomyopathy due to baclofen withdrawal syndrome associated with diffuse ST-segment depressions and ST-segment elevation in lead aVR.
