CARDENAS, Manuel et al. Prevalence of syncope in a sample of Mexican women residents in Mexico City. Arch. Cardiol. Méx. [online]. 2009, vol.79, n.3, pp.197-200. ISSN 1665-1731.

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.
