Background: Cardioembolic cerebral infarction (CI), or stroke, is severe and associated with a high risk of early and delayed mortality. The objectives of our study were to describe the demographic, clinical, etiological, and CT characteristics of patients suspected as having suffered a cardioembolic stroke. Method: This was a retrospective descriptive study carried out in the neurology department of Befelatanana University Hospital, Antananarivo, over eighteen months from January 1, 2018 to June 30, 2019. Results: A total of 120 cases were selected. The average age of patients affected was 62.45 years with ages ranging from 25 to 90 years with a male predominance (sex ratio of 1.2). Arterial hypertension (AH) was found in 69.13 percent of cases. The average NIHSS score at admission was 10.90. Atrial fibrillation (AF) was the cause of cerebral infarction in 13.30 percent of cases and the etiologies remain undetermined in the majority of cases (78.30 percent). The majority of these strokes occurred in the carotid territory (60 percent) and were multi-territory in 29.20 percent of cases. Hemorrhagic transformation was observed in 47.50 percent of cases. Conclusion: The profile of cardioembolic stroke is becoming increasingly well-known in Madagascar, according to the data provided by our study. Diagnosis remains difficult and requires an exhaustive etiological assessment.
