Abstract

Background: The Left atrium (LA) structure and function had recently gained increased interest as it potently predicts and indicates cardiovascular (CV) risks and adverse outcomes in a range of CV diseases. The purpose of this study is to assess the effect of sex group on the structural and functional variations of the left atrium in apparently healthy Iraqi people. Methods: Patients were split into two groups according to their sex. Both groups were subjected to routine history and clinical examination, a conventional 12-lead ECG focusing on P wave assessment for shape, duration, and amplitude; PR interval was measured. Also, a conventional, pulsed wave, and tissue Doppler imaging (TDI) assessment were performed. Results: There is a significant increase in A velocity, and a significant decrease in E/A, and e‘/a‘ ratios, in females in comparison to males no significant differences were observed in left atrial volume. Conclusion: Although there is a significant impact of sex on the left atrial contraction and diastolic function as there is a rise observed in “A velocity” and a statistically significant drop in “E/A” and “e’/a” ratios, which indicates an increase in atrial contraction during late ventricular filling in females compared to males. However, sex group has not proven to have a significant impact on LA volume. So, it must be taken in consideration other factors like age, menopause, and obesity indices together with sex which may permit the clarification of diastolic dysfunction’s underlying processes and viable therapies.
