Capecitabine-Induced Takotsubo Cardiomyopathy: A Case Report.

Introduction: The medication 5-fluorouracil is known to cause cardiotoxic effects (with an incidence ranging from 5% to 18%), such as rhythm abnormalities and cardiomyopathies, including takotsubo cardiomyopathy. Capecitabine, an oral prodrug of 5-fluorouracil, has rarely been reported to cause cardiotoxic effects compared with its parent drug.

Case Presentation: An 80-year-old woman presented to the hospital with chest pain after recent initiation of capecitabine use for anal cancer.
