Prevalência de Anemia e insuficiência r enal em Portadores de insuficiência Cardíaca Não-Hospitalizados Prevalence of Anemia and Renal Insufficiency in Non-Hospitalized Patients with Heart Failure
2009
Summary Background: Heart Failure (HF) is a common disease with a high rate of mortality. Anemia and renal failure (RF) are often found in patients with HF associated with higher severity of the heart disease and a worse prognosis. Objective: To evaluate the prevalence of anemia and RF, as well as the association between these two conditions, in non-hospitalized patients with HF. Methods: Patients treated at the HF Outpatient Clinic of a university hospital were followed from July 2003 to November 2006. Anemia was defined as hemoglobin levels < 13 mg/dl for men and 12 mg/dl for women. Renal function was assessed by the glomerular filtration rate (GFR), calculated by the simplified formula of the MDRD (Modification of Diet in Renal Disease) study. Results: Of the 345 patients included in this study, 26.4% (n = 91) had anemia and 29.6% had moderate to severe renal failure (GFR < 60 ml/min). The association between anemia and a higher prevalence of renal failure was statistically significant (41.8% vs. 25.2%; p = 0.005). The patients at functional class III and IV presented a higher incidence of anemia (39.0% vs. 19.4%; p <0.001) and renal failure (38.2% vs. 24.8%; p = 0.007). No association was observed between anemia or renal failure and history of hypertension, diabetes, systolic function or etiology of HF.
