title: Left atrial function predicts heart failure events in patients with newly diagnosed left ventricular systolic heart failure during short-term follow-up.
abstract: We assessed the effect of left atrial (LA) function index, LA ejection fraction, LA kinetic energy, and maximal LA volume on 6 months clinical outcome in patients with newly diagnosed systolic heart failure (HF). During a 36-month period, 179 consecutive patients (17% female, mean age 63 ± 14 years) were enrolled. During the follow-up, 46 patients had an event (32% event rate; 15 were fatal). Those with an adverse event were older, had lower creatinine clearance, advanced New York Heart Association stage, higher prevalence of ischemic HF, and lower values for right ventricle systolic wave in the tissue Doppler imaging evaluation, compared with those without an event. Multivariate analysis revealed that LA function and ischemic etiology of HF were the most significant prognostic indicators after index hospitalization. This study reveals the important role of LA function for the short-term prognosis of patients with newly diagnosed systolic HF in sinus rhythm.
