[Reversible cardiogenic shock due to 5FU. Apropos of a case report].

The authors report the case of a man with a laryngeal neoplasm treated by chemotherapy including 5 FU who presented a severe cardiogenic shock responding to medical therapy with a favourable outcome. This classical clinical presentation is commented by the authors. Based on the electrocardiogram, the echocardiography and a review of literature, they favour as first underlying hypothesis the secondary metabolic pathway linked to ribonucleic acid (RNA), rather than a possible coronary spasm.
