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.
