title: The changes of cardiac ejection fraction up to 72 h after transfusion in patients with chronic anaemia.
abstract: The objective was to assess the serial change of the cardiac function after blood transfusion in patients with chronic anaemia. According to a previous study, transfusion would adjust the ejection fraction to the advantage of cardiac function in chronic anaemia patients, and thus the serial change of the cardiac function in a certain period should be evaluated after transfusion in patients with chronic anaemia. In a prospective study, ejection fraction (EF) was determined before and < or = 6 h, 24 h and 72 h after transfusion in 32 patients with chronic anaemia, and the results were compared and analysed. In the left ventricle (LV), the four EFs noted before and < or = 6 h, 24 h and 72 h after transfusion did not significantly differ between one another. In the right ventricle (RV), the EF 72 h after transfusion significantly increased in comparison with the pretransfusion value (P = 0.043). Transfusion of small amounts of RBC did not significantly change the LVEF up to 72 h in patients with transfusion-dependent chronic anaemia; whether it might change the RVEF 72 h after transfusion deserves further investigation.
