dc.description.abstractObjective: Atrial functions are relatively suppressed in heart failure (HF). We aimed to investigate the associations of intra- and inter-atrial electromechanical conduction delay (EMCD) with functional class and mortality over a 12-month follow-up period.Methods: the prospective study included 65 patients with systolic HF and 65 healthy subjects with normal sinus rhythm. Left ventricular (LV) systolic functions and left atrial (LA) dimensions and volumes were evaluated by transthoracic echocardiography. Tissue Doppler imaging (TDI) signals at the lateral border of the mitral annulus (lateral PA'), septal mitral annulus (septal PA'), and tricuspid annulus (tricuspid PA') were measured. Intra- and inter-atrial EMCD were calculated.Results: Mitral inflow velocities were studied using pulsed-wave Doppler after placing the sample volume at the leaflets' tips. the peak early (E wave) and late (A wave) velocities were measured. the septal annular E/E' ratio was relatively higher and lateral, septal, and right ventricular S, E', and A' waves were significantly lower in the HF group than in the control group (12.49±6.03 - 7.16±1.75, pE/E' <0.0001). Intra-atrial EMCD was detected as 117.5 ms and inter-atrial EMCD as 127.5 ms in patients with prolonged atrial EMCD. A significant increase was found in prolonged intraand inter-atrial EMCD according to functional capacity increase (p=0.012 and p=0.031, respectively). the incidence of mortality was significantly higher in patients with prolonged atrial EMCD (p=0.025), and 5 patients in the HF group died during the study over the 12-month follow-up period.Conclusions: in this study, we found a relationship between prolonged atrial conduction time and increased functional class and mortality in patients with systolic HF.en_US
