Mortalité à 3 mois des infarctus cérébraux au Burkina Faso : une étude de cohorte prospective

Abstract

Mortality at 3 months of cerebral infarction remains high in sub-Saharan Africa. The aim of our study was to evaluate the intra-hospital mortality, at one month and at three months, of patients hospitalized for cerebral infarction in Burkina Faso. This was a prospective cohort study of patients consecutively hospitalized for cerebral stroke, at the Tingandogo University-Teaching Hospital in Ouagadougou, Burkina Faso from March 2015 to February 2016. Then they were followed-up as neurology outpatients for at least 3 months after the stroke. The baseline characteristics of the patients at admission, complications and cumulative mortality rates using survival curves, were analyzed at the discharge from hospital, at 1 and 3 months post-stroke. A total of 151 patients were registered, among which male patients represented 59.6%. The mean age was 63.4 years. At the end of the hospitalization, then at 1 and 3 months post-stroke, 27 (17.9%), 30 (19%) and 39 (25.9 %) patients died, respectively. The mortality rates from cerebral stroke remains high in Sub Saharan Africa, mainly due to the weaknesses of the health systems. An improvement in the quality of care, including fibrinolysis, early admission to stroke units, adequate management of comorbidities, complications and elderly patients, will contribute to an improvement of the survival of patients following the first three months after the stroke.
