[Upper gastrointestinal tract hemorrhages following heart surgery].

The clinical histories of 612 patients who underwent an operation of the heart were evaluated. Eight times a more severe haemorrhage from the upper gastrointestinal tract was described, i.e. 1.3%. One patient died under the signs of the septic shock. All patients were treated conservatively, only in one patient an ulcer existed 12 years before the heart operation.
