Clinical aspects of heart failure: Trepopnea

: Most patients with chronic heart failure feel uncomfortable in left lateral decubitus position (LLD). They suffer from trepopnea. In LLD position cardiac sympathetic activity and preload are increased. Cardiac output is decrased. The right lateral decubitus position (RLD) can help to avoid discomfort in heart failure. RLD position may be a self-protective strategy of patients with heart failure to gain preferable hemodynamic parameters.
