Prevalence of Carotid Disease after Stroke in a Teaching Hospital of Bogota, Colombia

Objective: To establish the prevalence of carotid stenosis (>= 50%) in a population with stroke between the years 2014 to 2018 and to compare it with the previous data. Methods: A cross-sectional study was performed. Patients older than 18 years with acute ischemic stroke were included, who in the etiological evaluation documented a significant carotid stenosis (>= 50%), with a description of their main risk factors, studies and interventions. Results: Of 413 patients with stroke, 51 patients with stenosis > 50% were found with a prevalence of 12.3%. The former prevalence between 1996-2002 was 16%. Mean age was 78 years with men (51%). Among the risk factors, there was a higher proportion of arterial hypertension (76.5%), followed by dyslipidemia (47%). In 15/51 of the cases it was possible to check the agreement in the diagnostic imaging tests, with a concordance of 54% to qualify the stenosis grade. In 59% of the subjects the etiologic classification of the stroke was due to great vessel disease, with a small percentage of surgeries (12%). Conclusions: A similar prevalence of carotid stenosis was found regarding previous literature, with the decreased in risk factors like smoking and less atherosclerotic markers and lower coronary artery disease.
