L’anémie dans l’insuffisance cardiaque

Abstract

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