AS, characterized by increased pulse wave velocity (PWV) may impair LA phasic function. This study investigates the associations of brachial-ankle PWV and the left atrioventricular coupling index (LACI) as well as LA phasic function in hypertensive patients, and to evaluate the predictive value for LA dysfunction.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A prospective cohort of 150 patients with essential hypertension was enrolled.

LACI was significantly higher in Group II (P\u2005&amp;lt;\u20050.05). After adjusting for cardiovascular risk factors, multivariate linear regression analysis revealed that baPWV remained independently associated with LAVImin, LACI, \u03b5s, and \u03b5e. baPWV integration with conventional risk factors significantly improved predictive performance. The AUC increased from 0.709 to 0.845 for LACI, from 0.681 to 0.892 for LAVImin, from 0.672 to 0.881 for \u03b5s, and from 0.685 to 0.919 for \u03b5e.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Hypertension-mediated AS exhibits concurrent abnormalities in LA-arterial and LA-LV-arterial coupling.
