Cardioembolic Cerebral Accident: Epidemiological and Paraclinical Aspects at the Brazzaville University Hospital

Purpose: to show the value of the Doppler echocardiogram and the Holter-ECG performed systematically during the etiological assessment of a first episode of ischemic stroke. Methods and patients: this was a prospective and descriptive study, carried out from May 1 to October 31, 2020 (six months) in the cardiology and neurology departments of the Brazzaville University Hospital Center. It included patients who had a first episode of ischemic stroke confirmed on brain scan and carried out a cardiological assessment. Results: fifty patients were included, including 26 women. The mean age was 63.9 ± 12.8 years (34 - 82 years). Transthoracic echocardiography and ECG detected emboligenic heart disease in 42 cases (84%), major heart disease in 38 cases (76%). The major emboligenic heart disease was dilated cardiomyopathy in 17 cases (34%); ischemic heart disease in 6 cases (12%), mitral stenosis in 2 cases (4%), and atrial fibrillation in 13 cases (26%). The Holter-ECG revealed permanent atrial fibrillation in 13 patients (26%), paroxysmal atrial fibrillation in 1 patient, paroxysmal atrioventricular block in one patient. Conclusion: in our work, the echocardiogram and the Holter -ECG made it possible to identify twenty-nine thromboembolic causes of stroke. These explorations are essential in the etiological assessment.
