ABSTRACT

OBJECTIVE: To identify the frequency of syncope in a sample of women regular residents of Mexico City. METHODS: Two hundred and twenty one women between 18 and 88 years old with voluntary participation were included in the study. Trained interviewers through a structured questionnaire obtained syncope information. Prevalence of syncope was obtained, and it's relation with: age, time since the last syncope and frequency of syncope in their live span was registered. RESULTS: Thirty eight percent informed they had suffered syncope, of them 50% had only one syncopal episode during their lives. The others had two or more episodes. Most women had their last syncope between 19 and 50 years of age. CONCLUSIONS: The frequency of syncope was a little higher than previous studies. This is a first approximation, which must be corroborated with larger studies with well population variability representation.

ABSTRACT

En los pacientes con intolerancia ortostática, la respuesta hemodinámica al adoptar la posición de pie puede identificar una anormalidad: el síndrome de taquicardia postural ortortostática o una hipotensión ortostática (la cual a menudo puede ser tratada sin requerir de más estudios). Cuando la respuesta hemodinámica al ortostatismo activo es normal, la prueba de inclinación en mesa basculante se hace necesaria para establecer el diagnóstico y seleccionar un tratamiento, en el síncope vasovagal o en el síndrome de taquicardia postural ortostática. Durante la evaluación de la respuesta hemodinámica a la prueba de inclinación es importante la distinción entre el verdadero síncope vasovagal y la llamada respuesta disautonómica que se caracteriza por una disminución gradual y progresiva de la presión arterial que antecede al síncope. La practica clínica actual recomienda el empleo de ß bloqueadores adrenérgicos, fludrocortisona y midodrina para el tratamiento del síncope vasovagal, mientras que los pacientes con el síndrome de taquicardia postural ortostática o con la respuesta disautonómica son mejor tratados con fludrocortisona y midodrina.
