Les Causes de Ré-hospitalisation de l’Insuffisance Cardiaque au Service de Cardiologie du Centre Hospitalier Universitaire de Référence Nationale de N’Djamena: Causes of re-hospitalization of heart failure in the cardiology department of the National Reference Teaching hospital of N’Djamena

Abstract

Introduction. Heart failure (HF) is a disease with a dismal prognosis, whose evolution is punctuated by numerous re-hospitalizations. The aim of this study was to identify the causes of re-hospitalization in heart failure in order to help improve patient management. Patients and method. This was a prospective descriptive and analytical study conducted over a period of nine (09) months, from January 31 to October 30, in the cardiology department of CHU-RN. It involved all patients re-hospitalized for heart failure, regardless of age, sex, origin or profession, and who had freely agreed to participate in the study. Results. During the study period, we identified 216 patients hospitalized for heart failure, 59 of whom met the inclusion criteria, i.e. a frequency of 27.3%. The mean age of patients was 54.76 years. The female sex was the most represented with 54.2%, i.e. a sex ratio of 0.8. Age and hypertension were the main FRCV in 50.8% and 39% respectively. Stage IV dyspnea accounted for 40.7%, and hypertensive heart disease was the most common etiology in 39% of cases. 78% of patients had global CI. The mortality rate was 13.6%. The average length of hospital stay was 10 days. The majority of patients were re-hospitalized at least once (64.4%), and the most common cause was failure to comply with treatment (55.9%). Conclusion. CI remains a major public health problem. A considerable rate of re-hospitalization has been found to be linked to therapeutic non-adherence, with rupture followed by diet deviations. Better patient education could improve management and reduce the frequency of re-hospitalization
