The American College of Physicians (ACP) developed this guideline to present the evidence and provide clinical recommendations on the treatment of anemia and iron deficiency in adult patients with heart disease.
This guideline is based on published literature in the English language on anemia and iron deficiency from 1947 to July 2012 that was identified using MEDLINE and the Cochrane Library. Literature was reassessed in April 2013, and additional studies were included. Outcomes evaluated for this guideline included mortality; hospitalization; exercise tolerance; quality of life; and cardiovascular events (defined as myocardial infarction, congestive heart failure exacerbation, arrhythmia, or cardiac death) and harms, including hypertension, venous thromboembolic events, and ischemic cerebrovascular events. The target audience for this guideline includes all clinicians, and the target patient population is anemic or iron-deficient adult patients with heart disease. This guideline grades the evidence and recommendations using the ACP's clinical practice guidelines grading system.
ACP recommends using a restrictive red blood cell transfusion strategy (trigger hemoglobin threshold of 7 to 8 g/dL compared with higher hemoglobin levels) in hospitalized patients with coronary heart disease. (Grade: weak recommendation; low-quality evidence)
ACP recommends against the use of erythropoiesis-stimulating agents in patients with mild to moderate anemia and congestive heart failure or coronary heart disease. (Grade: strong recommendation; moderate-quality evidence)

We would like to respond to the recommendations for anemia treatment recently published in your journal that in our opinion deserves particular attention. The document concludes against the use of blood transfusions in patients with mild to moderate anemia. The use of erythropoiesis-stimulating agents (ESA) appears to increase the rate of thromboembolic and stroke events. (1)On the other hand Intravenous Iron administration improves quality of life and exercise tolerance. However, epidemiologic data showed that iron deficiency in HF is found in about half the CHF patients and more often in anemics than non anemic.Regarding ESA administration we would underline some aspects that do not emerge from the current and previous meta-analysis published in the Journal: (2)In the active arms ESA were sometimes administered together with iron in different dosages and different modalities. This could have had an impact on the results of the meta-analysis.The mean ESA dosage administration appears persistently higher as in the STAMINA as in the RED HF Trial respect to single center studies reported in the meta-analysis.(3) Especially if we contemplate the mean hemoglobin levels in the two Trials (11.5 gr/dl).(3,4)One third of patients recruited in the largest ESA Trial in HF anemic patients (RED-HF) had atrial fibrillation, a clinical condition that predisposes to peripheral and cerebral embolic events. Again, the prevalence of hypertensive patients was more than 70%. (4) All these points could explain the increased rate of adverse events in the active arm. Two other previous meta-analysis revealed different results: both studies showed a trend towards a decrease in hospitalization and improved exercise capacity in the active arm.(5,6) Moreover, there is now agreement that lower doses of ESA than were used in the STAMINA and RED HF studies should be used. In this context animal studies confirmed the ancillary effect of ESA: erythropoietin appears to increase vascular and endothelial grow factors after myocardial infarction, moreover it increases expression of heavy chain of myoglobin, nitric oxide liberation improving oxygen transport. (7) Most of these beneficial effects occur independently from the dose of ESA and appear only partially related to hematocrit improvement.(8) All these concerns raise several questions that should be better elucidated: the optimal hemoglobin intervention target is unknown; the clinical characteristic of patients and their co-morbidities should be better specified. In summary, there is a need to know the exact criteria for anemia definition in HF patients as well as the exact disorder of erythroid metabolism before writing the term “end” for ESA administration in anemic heart disease patients.1- Qaseem A, Humprey LL, Fitteman N, Starkey M, Shekelle P.
