We have often found that patients with heart failure had shortness of breath when bending forward. The frequency of bendopnea in patients with decompensated heart failure (DHF), its repercussions on quality of life (QoL), and its prognosis have not yet been studied. This study was carried out to evaluate the characteristics, degree of limitation, and short-term prognosis of patients with bendopnea and DHF. ⋯ Bendopnea is related to advanced HF symptoms and it is associated with mortality in the short term and advanced NYHA functional class. This symptom produces moderate to severe limitation of QoL.

Left ventricular deformation at rest predicts exercise-induced elevation in pulmonary artery wedge pressure in patients with unexplained dyspnoea.
Impaired left ventricular (LV) deformation despite preserved LV ejection fraction (LVEF) is common and predicts outcomes in heart failure with preserved LVEF. We hypothesized that impaired LV deformation at rest is a marker of impaired cardiac systolic and diastolic reserve, and aimed to determine whether resting longitudinal (LS) and circumferential strain (CS) are associated with invasively measured haemodynamic response to exercise in patients with dyspnoea and a normal LVEF. ⋯ Left ventricular deformation at rest predicts exercise-induced rise in PAWP among patients with dyspnoea and a preserved LVEF. A pattern of rest deformation characterized by worse LS and exaggerated CS is most strongly associated with exercise-induced rise in PAWP.
