Intracardiac energy inefficiency during decompensated and compensated heart failure.

ABSTRACT:

Aims

The mechanisms underlying the acute decompensation of heart failure (HF) remain unclear. The present study examined intracardiac dynamics during decompensated HF using echo-vector flow mapping.

Methods and results

Fifty patients admitted for decompensated HF were prospectively enrolled, and intracardiac energy loss (EL) was assessed by echo-vector flow mapping at admission (decompensated HF) and discharge (compensated HF). Outcome measures were average EL in the left ventricle (LV) in decompensated and compensated HF and were compared with those in 40 stable non-HF patients with cardiovascular diseases. The mean age of HF patients was 80.8 ± 12.4 years. The prevalence of both females and atrial fibrillation was 48.0%. The prevalence of HF with a reduced ejection fractio
