Cardioembolic stroke is serious and associated with high early and late mortality. The objectives of our study were to describe the demographic, clinical, etiological, and CT characteristics of patients diagnosed with presumed cardioembolic stroke.MethodsThis was a retrospective, descriptive study carried out in the neurology department of Befelatanana University Hospital over 18 months from January 2018 to June 2019.ResultsOne hundred and twenty cases were selected. The mean age was 62.45 years with extremes of 25 to 90 years, and male predominance (sex ratio of 1.2). Arterial hypertension (hypertension) was found at 69.13% of cases. The mean NIHSS score at admission was 10.90. Atrial fibrillation (AF) was cited as the cause in 13.30% of cases; etiology was unknown in the majority of cases (78.30%). The main site of stroke was the carotid artery (60 %); multiple territories were involved in 29.20% of cases. Hemorrhagic transformation was observed at 47.50% of cases.ConclusionThe profile of cardioembolic cerebral infarctions is becoming better known in Madagascar, notably through data provided by our study. Diagnosis remains difficult and requires an exhaustive etiological assessment.
