Anemic syndrome in patients with ischemic heart disease and chronic heart failure (review)

Abstract

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
