[A case of Schönlein-Henoch purpura with myocardial complications].

A rare case of Schönlein-Henoch purpura with myocardial complications was reported. A 64-year-old man was admitted to our hospital for further examination of hematuria, associated with arthralgia, proteinuria, and previous episodes of anasarca and orthopnea. The examinations revealed moderate renal dysfunction due to mesangial proliferative glomerulonephritis secondary to Schönlein-Henoch purpura. In addition, the patient proved to have cardiac dilatation and dysfunction of the left ventricle. The histological examination of the right ventricular subendocardium sampled by myocardial biopsy showed myocardial damage, suggesting the invasion of microvasculitis in Schönlein-Henoch purpura to the peripheral coronary vessels. These findings indicate that myocardial damage induced in the patient may be one of the complications caused by Schönlein-Henoch purpura.
