title: [Emergency coronary angioplasty following treatment with 5-fluorouracil].
abstract: BACKGROUND
  The incidence of cardiac toxicity due to 5-fluorouracil (5-FU) ranges from 1.2 to 18%. Most complications occur at the time of the first cure. Their mechanisms have not yet been clearly defined.
  
  
  METHODS
  The authors report a case of unstable angina induced by 5-FU. A coronary angioplasty was performed on a previously ignored coronary lesion.
  
  
  CONCLUSIONS
  Recent studies support the hypothesis that 5-FU has endothelial toxicity resulting in thrombogenic effect and release of vasoactive substances. Unstable angina pectoris would be related to plaque rupture caused by 5-FU. Patients with previous history of coronary disease are at significantly increased risk for 5-FU-induced cardiotoxicity. They probably would benefit from continuous electrocardiographic monitoring. Rechallenge with 5-FU after cardiotoxicity problems should include only those patients for whom there is no alternative treatment.
