N2 - Background: Stroke burden is highest and is still rising in low- and middle-income countries. Epidemiologic stroke data are lacking in many of these countries. Stroke prevalence in Argentina has been unexplored for almost three decades. Aim: This population-based study aims to determine prevalence of stroke in a representative sample of the Argentinean population. Methods: We performed a door-to-door survey of randomly selected households in a city of 18,650 inhabitants. A structured questionnaire screening for potential stroke cases was used. All subjects screened positive were then evaluated by stroke neurologists for final adjudication. Data about stroke subtypes, neurological status, vascular risk factors, medications, and diagnostic tests were also collected. Results: Among 2156 surveys, 294 were screened positive for a possible stroke. After neurological evaluation, there were 41 confirmed cases. The adjusted stroke prevalence was 1,974/100,000 inhabitants older than 40 years, and it was higher in men than in women (26.3‰ vs 13.2‰, p<0.01). Prevalence of ischemic stroke, intracranial hemorrhage, and transient ischemic attack were 15.8‰, 2.93‰, and 2.93‰, respectively. The most prevalent vascular risk factors in stroke survivors were hypertension, obstructive sleep apnea, and dyslipidemia. Conclusion: Approximately 2 in every 100 subjects older than 40 years in this population are stroke survivors. Stroke prevalence in Argentina has remained stable over the last 30 years; it is higher than in most Latin American countries and similar to western populations.
