[Anemia in congestive heart failure].
Anemia is a common disorder in congestive heart failure and an independant prognostic factor. The aims of this study are to evaluate the prevalence of anemia among a population of in-hospital congestive heart failure patients, to compare anemic patients (A) with non anemic patients (NA) and to study their cares.


RESULTS
One hundred and thirty-two patients, 70 men (53%), et 62 women (47%) are enrolled. Mean age is 76.4+/-13.5 years. The prevalence of anemia (WHO criteria) is 49%. Patients A are older than NA: 79.1+/-13.8 years versus 73.8+/-12.9 years (p=0.025), renal function is more altered in A than in NA, creatinine clearance is 56.5 ml/min (A) versus 76.2 ml/min (NA) (p=0.003). Ejection fraction (EF) is lower in A than in NA: 35.1+/-15.3% versus 50.9+/-15.9%, (p<0.0001.) Anemia is less frequent in preserved EF (28%) than in low EF (63%) (p<0.0001). Hospitalization duration is longer in A than in NA: 10.7+/-10.1 days versus 6.9+/-3.7 days (p=0.005). There are more re hospitalized patients among A than NA: 38 versus 10 (p=0.0001). There is a significant difference of survival of NA versus A at day 614 (p=0.03).


CONCLUSIONS
Anemia is frequent in our population, and is associated with others prognostic factors and comorbidity.
