Prevalence of anemia in a Hispanic population with decompensated congestive heart failure.
Anemia in patients with heart failure (HF is a frequent event, commonly associated with worse prognosis. Despite the high incidence and adverse outcomes associated with anemia no studies have been conducted amongst Hispanics with HF.


OBJECTIVE
The study aims to determine the prevalence, predictors and outcomes of anemia in Hispanics admitted to Veteran Affairs Caribbean Healthcare System with diagnosis of Decompensated Congestive Heart Failure (D-CHF).


METHODS
Retrospective review of 617 patient medical charts that had been previously discharged with a diagnosis of HF as per International Classification of Diseases-9 code. The clinical, demographic, laboratory and echocardiographic data was assessed for a total of 148 male patient electronic medical records that met the study inclusion criteria. The re-hospitalization and mortality rates were determined from the admission date until April 2010.


RESULTS
The burden of anemia with HF is substantial, with anemia present in 68.2% of patients. Anemia was associated with hypoalbuminemia, higher New York Heart Association classification, elevated pro-BNP level at discharge, renal insufficiency and diastolic dysfunction, all of which demonstrated statistical significance. Anemia had 2.18 and 2.95 times likelihood of any-cause mortality (p = 0.003) and cardiovascular deaths (p = 0.02) when compared with HF patients without anemia.


CONCLUSIONS
Anemia is a very frequent and serious finding in patients with D-CHF. The study reveals a higher prevalence of anemia in HF patients among Hispanics in comparison with formerly reported studies covering non-Hispanic populations.
