ABSTRACT
Introduction: Stroke in patients aged 20 to 55 years is an event of great impact. Several unusual atherothrombotic risk factors and different etiologies are involved in the pathogenesis of the lesion, which gives rise to a variety of stroke subtypes. Many risk factors and etiologies have been studied but the results are unclear and/or discordant.
Objective: To identify the risk factors for stroke and the etiological subtypes according to the
Trial of Org 10 172
in Acute Stroke Treatment (TOAST) criteria in patients aged 20 to 55 years.
Methods: A retrospective, cross-sectional and descriptive research study was conducted in 175 patients diagnosed with stroke and aged 20 to 55 years. They had been admitted to "Hermanos Ameijeiras" clinical and surgical hospital from January 1st 2004 to September 30th 2014.
Results: The average age was 46 ± 7.6 years and males predominated. The atherothrombotic stroke (45.71 %) was the most common TOAST subtype. The most frequent factors were blood hypertension, dyslipidemias, smoking, alcohol consumption and overweight. For the cardioembolic origin (14.86 %), the main one was atrial fibrillation followed by myocardial infarction whereas for the unusual origin (16.57 %), the hypercoagulation alterations predominated. The undetermined origin accounted for 13.71 % of cases.
Conclusions: Blood hypertension was the most frequent risk factors for all types of strokes and the atrial fibrillation was the predominant cardioembolic etiology; atherothrombotic stroke was the most common.
