Transient left ventricular contractile dysfunction during the treatment of rhabdomyolysis: A case report and literature review

Abstract

Transient left ventricular contractile dysfunction (TLVCD) is often observed as a result of stress-related cardiomyopathy; however, recent reports suggest that rhabdomyolysis and eating disorders can also induce the development of TLVCD. We report a 52-year-old malnourished man who developed acute heart failure on day 4 of treatment for rhabdomyolysis. Transthoracic echocardiogram revealed severe hypokinesis at the apical and mid-ventricular segments, except for the basal segments of the left ventricular wall, which recovered within one week. We discuss the pathogenesis of TLVCD with sympathetic nerve activation in association with rhabdomyolysis or refeeding syndrome.
