Cardiac involvement in Henoch‐Schönlein purpura

Cardiac involvement is not regarded as a feature of Henoch‐Schönlein purpura (HSP). We report a patient with HSP who developed significant cardiac symptoms, which resolved with immunosuppression. We review previous cases of HSP with cardiac features, none of which showed a response to treatment, and discuss evidence that cardiac involvement is more common than recognized. The implications for investigation and treatment of this condition are discussed.
