Association of LAAWV values with the E/e’
Previous studies have highlighted the importance of left ventricular
(LV) filling parameters measured through Doppler echocardiography as
essential markers for predicting cardiac mortality in dilated
cardiomyopathy (DCM). Impaired LV relaxation is linked to a simultaneous
decline in both mitral inflow E waves and early diastolic flow in the
left atrial appendage (LAA). Furthermore, research has shown that
patients with a decreased LAA emptying velocity tend to have a higher
E/A ratio and a shorter deceleration time, suggesting a worse cardiac
status with a stiff ventricle and impaired atrial function. In our
study, we observed a significant inverse correlation between LAAW
velocity and E/e’ ratio, implying that reduced left atrial appendage
wall velocity strongly correlates with the severity of diastolic
dysfunction in this specific group of patients. These findings emphasize
the association between LAAW velocity and E/e’ ratio, as valuable
indicators of diastolic dysfunction and cardiac function in this group
of patients.
