ABSTRACT

Heart failure with preserved ejection fraction, characterized by the presence of diastolic dysfunction, affects more women than men. A decrease in the phasic function of the left atrium has been found in individuals with diastolic dysfunction in pre-clinical stages. It is unknown if such deterioration is greater in women. Objective: To determine if there are differences in the phasic function of the left atrium obtained by «strain» analysis by speckle-tracking technique (2D-STE), in individuals with preclinical diastolic dysfunction in relation to sex. Material and methods: This is an observational, cross-sectional and analytical study which included 53 subjects of both sexes (62% men) with ejection fraction greater than 50% in stage I of NYHA. Results: In individuals with diastolic dysfunction, left atrial reservoir function determined by 2D-STE, was lower compared with individuals with normal diastolic function (37.6% vs 30.3%, p‹0.0001). However, no significant differences were found between men and women. Conclusion: The decrease in reservoir function was similar for individuals of both sexes, in preclinical stages of diastolic dysfunction. Sex does not seem to be a determining factor for the development of alterations in left atrial function, at least in the reservoir phase.
