摘要
To improve the management of patients with heart failure and anemia at the University Hospital of Brazzaville, a cross-sectional study of patients diagnosed with heart failure condition (left or global heart failure) was conducted over a period of nine months from January 1 to September 30, 2017. A total of 171 patients were included during the study period. Study participants were divided into two groups: Group A included patients with an additional anemic condition (n = 57) and Group NA patients without anemia (n = 114). Anemia was defined as a hemoglobin rate of < 12 g/dL for men and <11 g/dL for women. All eligible patients admitted to the Department of Cardiology were included in the study. The frequency of anemia was 33.3%, with a mean hemoglobin level of 9.4 ± 1.5 g/dL. Men accounted for 46.9% of cases (n = 79) and women 53.8% (n = 92). The mean age of eligible patients was 57.5 ± 16.5 years. Of these, 46.2% (n = 75) had a secondary educational level and 53.8% (n = 92) had a low socioeconomic status. Heart failure was global in 153 cases (89.5%). Patients were on NYHA III-IV functional class in 112 cases (65.5%), with a statistically significant difference between anemic and non-anemic patients (p = 0.0001). The main underlying heart diseases were dilated cardiomyopathy (75.1%), hypertensive heart disease (10.5%), ischemic heart disease (6.5%), and valvular disease (4.7%). The comparison between the two groups (A and NA) showed a longer hospital length of stay (18.4 ± 8.9 versus 12.9 ± 7.6 days;p = 0.00001) and a higher mortality rate (4 versus 2 deaths). The re-hospitalization rate was more important in group A (n = 4) than in group NA (n = 1). Anemia is a common condition in patients with heart failure. It worsens the clinical features and prognosis.
