| Abstract: | Objective To evaluate left atrial function in patients with hyperthyroidism.Methods Echocardiography of 80 hyperthyroidism patients was compared to that of 80 normal persons. Indexes such as systolic time interval and left atrial ejection force were studied.Results All indexes of left atrial volume and left atrial ejection time interval (LAET) were significantly higher than those of nomal subjects. Left atrial pre-ejection time interval (LAPEP) and LAPEP/LAET ratio were significantly lower than normol. Left atrial ejection force (LAF) was positively correlated with left atrial ejection fraction (LAEF), while left ventricular stroke volume (LVSV) and left ventricular ejection fraction (LVEF) were negatively correlated with LAPEP/LAET ratio. Conclusion Left atrial contraction was increased in patients with hyperthyroidism. LAF may be used as a useful index for assessing atrial contraction. |
