Antimalarial-induced cardiomyopathy is under-recognized in clinical practice and there is limited data on the evolution of cardiac imaging abnormalities after cessation of anti-malarial therapy. In this case series of 9 patients with antimalarial-induced cardiomyopathy, follow-up cardiac magnetic resonance imaging demonstrated interval increase in late gadolinium enhancement extent in 89% of patients and interval decrease in left ventricular ejection fraction in all, despite cessation of anti-malarial therapy. Progression of cardiac abnormalities despite cessation of therapy underscores the important role of imaging in the early recognition of antimalarial-related treatment changes.
