Psoriasis-induced postoperative cardiac failure.

Erythroderma-induced cardiogenic shock is a rare but known manifestation of erythrodermic psoriasis. Erythrodermic psoriasis is an aggressive form of the disease and can be precipitated by numerous factors including stress to the body. In this article we present a case of persistent severe vasodilatation after coronary artery bypass surgery that required prolonged epinephrine administration. This was caused by a flareup of erythrodermic psoriasis that was previously only controlled by methotrexate. This drug was omitted in the perioperative phase. Vasodilatation disappeared after treatment was reinstituted.
