Aim. To estimate the effect of anemia of chronic diseases on the processes of cardiovascular system remodeling in patients with dilated cardiomyopathy and ischemic cardiomyopathy. Methods. The study included 27 patients with dilated cardiomyopathy with anemia, 19 with dilated cardiomyopathy without anemia, 11 with ischemic cardiomyopathy with anemia, 34 with ischemic cardiomyopathy without anemia, and 30 healthy individuals. In these comparison groups, peripheral blood, mean corpuscular hemoglobin and mean cell hemoglobin concentration, reticulocytes, serum iron and ferritin were examined. Electrocardiography, echocardiography, scintigraphy and coronary angiography were performed. Results. In all groups identical signs of chronic heart failure class 3 and 4 were found to be predominant, which was confirmed by a significant decrease of blood pressure, stroke volume, ejection fraction, increase of end systolic and diastolic volumes and sizes, as well as left and right atrial size. Patients with dilated and ischemic cardiomyopathy with anemia had decreased hemoglobin, number of erythrocytes and platelets, positive correlation between hemoglobin and serum iron (r=0.49, p=0.000), red blood cells and ferritin (r=0.61, p=0.000), negative correlation between hemoglobin and ferritin (r=-0.51, p=0.02). In ischemic cardiomyopathy with anemia positive correlation was found between hemoglobin and serum iron (r=0.54, p=0.000), erythrocytes and ferritin (r=0.49, p=0.03), negative correlation - between hemoglobin and ferritin (r=0.54, p=0.03). Conclusion. In patients with dilated and ischemic cardiomyopathy no significant effect of anemia of chronic diseases on heart remodeling processes was revealed.
