【 摘 要 】

Abstract: In a cohort of patients hospitalized with acute heart failure (AHF) the prevalence of anemia and the existence of a correlation between anemia and the severity of the clinical picture were assessed. Methods: 50 consecutive patients (34 men, 16 women, mean age 67.5 years) hospitalized with AHF were enrolled.  Statistical analysis was performed for studying correlations between anemia and the presence/levels of diverse parameters (clinical, laboratory, echocardiographic, treatment related)  reflecting the severity and prognosis of AHF (α=0.05). Results: 21 patients (14 men, 7 women, mean age 69.6 years), representing 42%, had anemia  at admission. Comparing patients with and without anemia there were no significant differences regarding age,  gender,  presence of atrial fibrillation (p=0.75), diabetes (p=1), ischemic heart disease (p=0.9), left ventricular ejection fraction (EF) (p=1), hypotension (p=0.34) and tachycardia>100 b/min at admission (p=0.75), level of eGFR (p=0.72), and need of high dose (>80 mg/day)  loop diuretic (p=0.23). However, EF showed a significant positive correlation with eGFR only in AHF patients with anemia (r=0,65, p=0.001). In a multiple regression model, EF had a significant effect on the eGFR quartiles (p=0,004). Conclusions: Anemia is a frequent finding in patients hospitalized with AHF. The presence of anemia was not correlated with other factors related to AHF severity and prognosis. However, a low EF associated with low eGFR was characteristic for patients with anemia, suggesting that the decrease of renal perfusion by low cardiac output further aggravates anemia on the background of chronic kidney disease.
