Mild chronic anemia following heart transplantation: a syndrome with prognostic relevance?

The clinical relevance of mild chronic anemia in patients after heart trans plantation (HTX) has not yet been demonstrated. Forty-five outpatients who had undergone HTX 2-99 months prior to investigation and who had not receiv ed blood transfusions or erythropoietin (EPO) before data acquisition were observed over a period of 37 months. Anemia was found in 36 of the 45 patie nts and was normocytic, normochromic, and slightly anisocytotic (coefficien t of variation = 16 rt 2, normal 11.5-14.5). Anemic patients showed elevate d EPO levels, whereas in nonanemic patients EPO levels were normal. Surviva l after HTX differed significantly in anemic and nonanemic patients (P < 0. 02), with 100 % survival in the nonanemic and 85 % in the anemic group. Chr onic anemia in patients after HTX shows a typical pattern. Even when mild, anemia in patients after HTX seems to be of prognostic value and thus might be an indicator of chronic disorders.
