Abstract

Background. Anaemia increases morbidity and mortality in patients with congestive cardiac failure (CCF). Few studies have examined the prevalence of anaemia and its impact among patients with CCF in sub-Saharan Africa. We assessed the prevalence of anaemia and its influence on treatment outcome in patients with CCF attending a large referral hospital in Kampala, Uganda.
Methods. Echocardiography was done and haemoglobin levels were determined in 157 patients with CCF admitted to Mulago Hospital. The patients were followed up for 2 weeks and their treatment outcome was recorded.
Results. Of the 157 patients, 101 (64.3%) had anaemia (mean
haemoglobin concentration .11.9 g/dl for women and .12.9 g/dl for men) at admission. Increasing age and hypertensive heart disease were significantly associated with anaemia (odds ratio (OR) 2.92, confidence interval (CI) 1.41 - 6.05, p<0.01 and OR 0.31, CI 0.13 - 0.74, p< 0.01, respectively). In-hospital mortality at the end of the 2 weeks of treatment was 10.2% and was significantly higher among the anaemic
patients than their non-anaemic counterparts (OR 4.9, CI 1.07
- 22.35, p<0.03). The mean duration of in-hospital stay was 7.5
(standard deviation 3.4) days. This did not differ significantly
between anaemic and non-anaemic patients.
Conclusion. The prevalence of anaemia among patients with CCF attending Mulago Hospital was high. Anaemia in these patients was significantly associated with mortality by the end of 2 weeks of treatment.
