Anemia and chronic heart failure (CHF): Prevalence and prognosis: About 3000 cases - 25/12/18
Résumé |
Introduction |
Anemia is common in patients with heart failure (HF) and it is one of many factors whose presence allows us to draw a gloomy prognosis. The aim of the study was to determine the prevalence of anemia, its potential prognostic impact and its physio-pathological mechanism in patients suffering of heart failure.
Methods |
Retrospective study of all CHF patients registered in the therapeutic Unit of Chronic Heart failure over a period of 8 years, between June 2006 and March 2015. Anemia is defined as a hemoglobin level less than 11g/dl. During this period 3000 patients were studied and divided into two groups: Group 1 with anemia (58.5%) and group 2 without anemia (41.5%).
Results |
The mean age is 66 years in the group 1 and 65 in the group 2. A male predominance in both groups was notified. Ischemic heart disease was the most common etiology in both groups. The average heart rate of group 1 was higher than the group 2. It was found that the group 1 was more symptomatic than the group 2 and these patients had more cardiac decompensation. The atrial fibrillation in group 1 and group 2 was respectively 6.9% and 10.9%. Renal failure was significantly more frequent in group 1 (34.3%) than the group 2 (10.3%). There was not much difference concerning therapeutic classes used in both groups. The presence of anemia increases the risk of re-hospitalization and mortality rate at 4 years.
Conclusion |
In the context of heart failure, anemia is a common complication as shown in our study. It is an important and common factor for predicting unfortunate evolution in patients with HF. An early and appropriate management of anemia would improve the symptoms of these patients and reduce the frequency of re-hospitalization.
