Anemic syndrome of different severity often accompanies ischemic heart disease (IHD) and chronic heart failure (CHF). Anemia has association with unfavorable prognosis in patients with all forms of CVD — acute and chronic. In this article the authors summarize a literature review of English articles dedicated to the problem of anemia and ischemic heart disease (IHD) and the results of original research on the relationship between anemic syndrome and prognosis in the hospitalized patients with IHD and chronic heart failure (CHF). Anemia is frequently observed in patients with CHF, and evidence suggests that anemia might be associated with an increased mortality in both systolic and diastolic chronic heart failure (CHF), morbidity and rate of hospitalization in CHF patients. Moreover, CHF itself could be involved in the pathogenesis of anemia. Early studies suggested a pathogenic role of inflammation mediators. The normalization of hemoglobin concentration by EPO and iron supply in patients with CHF and chronic renal insufficiency results in improved exercise capacity by increasing oxygen delivery and improving cardiac function. However, there is limited information concerning the association of hemoglobin concentration and new onset of clinically recognized coronary artery disease, and lack of information about the effect of anemia treatment on prognosis of acute forms of IHD

NO-donating ability of nitrosyl [Fe–S] complexes, namely, mononuclear dinitrosyl complexes of anionic type [Fe(S2O3)2(NO)2]-(I) and neutral [Fe2(SL1)2(NO)2] with L1 = 1H-1,2,4-triazole-3-yl (II); tetranitrosyl binuclear neutral complexes [Fe2(SL2)2(NO)4] with L2 = 5-amino-1,2,4-triazole-3-yl (III); 1-methyl-1H-tetrazole-5-yl (IV); imidazole-2-yl (V) and 1-methyl-imidazole-2-yl (VI) has been studied. In addition, Roussin’s “red salt” Na2[Fe2S2(NO)4]·8H2O (VII) and Na2[Fe(CN)5NO]·H2O (VIII) have been investigated. The method for research has been based on the formation of Hb–NO adduct upon the interaction of hemoglobin with NO generated by complexes I–VIII in aqueous solutions. Kinetics of NO formation was studied by registration of absorption spectra of the reaction systems containing Hb and the complex under study. For determination of HbNO concentration, the experimental absorption spectra were processed during the reaction using standard program MATHCAD to determine the contribution of individual Hb and HbNO spectra in each spectrum. The reaction rate constants were obtained by analyzing kinetic dependence of Hb interaction with NO donors under study. All kinetic dependences for complexes I–VI were shown to be described well in the frame of formalism of pseudo first-order reactions. The effective first-order rate constants for the studied reactions have been determined. As follows from the values of rate constants, the rate of interaction of sulfur-nitrosyl iron complexes (I–VI) with Hb is limited by the stage of NO release in the solution.
