【Objective】 To investigate the prevalence and clinical implication of anemia in patients hospitalized for chronic heart failure.【Methods】 Retrospectively analyzed the clinical data of CHF patients hospitalized in Sun Yat-sen Memorial Hospital

calculated the prevalence of anemia (defined as Hb less than 120 g/L)

compared the difference between anemia group and no anemia group

including the clinical and chemical feature and mortality

and defined the independent risk factors of anemia by binary logistic regression. 【Results】 A total of 666 patients were investigated

with mean age 65 (S = 14) years and mean Hb 128 (S = 20) g/L. The prevalence of anemia was 32.58%. Compared with no anemia group

the anemia group involved more female

elderly

low body weight

and more coronary heart disease and HBP

ankle edema

pulmonary edema and pleura effusion were more common

eGRF and plasma albumin were lower but serum creatinine

blood urea nitrogen and LVEF were higher

and the hospital duration was longer. The in-hospital mortality was increased in anemia group (9.7% vs 5.3%

P = 0.037). Binary logistic regression showed that female sex (OR = 2.87

P < 0.001)

advanced age (for every 5 years

OR = 1.09

P = 0.02)

high NYHA grade (OR = 1.27

P = 0.029) and elevated SCr (for every 10 ?滋mol/L

OR = 1.08

P < 0.001) were the independent risk factors of anemia.【Conclusions】Anemia was a relatively common finding in hospitalized CHF patients

especially in female

elderly

severe CHF and impaired renal function

and might indicate adverse clinical outcome.
