New echocardiographic indices of shift to biventricular failure to optimize risk stratification of chronic heart failure.

ABSTRACT:

Aims

The present study investigated the prognostic impact of either isolated left atrial (LA) impairment, or its association with right ventricular (RV) failure, in heart failure (HF) with reduced ejection fraction (HFrEF), using basic and speckle tracking echocardiography (STE).

Methods and results

One hundred and six outpatients with HFrEF were enrolled in this prospective observational study. Patients with primary lung diseases, non-sinus rhythm, previous cardiac surgery, and poor acoustic window were excluded. After clinical examination and basic echocardiography, STE was used to measure peak atrial longitudinal strain (PALS) and a new marker of RV performance and pulmonary circulation relation: free-wall RV longitudinal strain (fwRVLS)/systolic pulmonary artery pressure
