There is great interest in better characterizing patients with heart failure (HF) with preserved ejection fraction (HF-PEF). The objective of this study is to determine the prevalence, progression over time and to describe the clinical and epidemiological characteristics of patients with HF-PEF. ⋯ Sixty percent of patients in the RICA registry have preserved ejection fraction. These patients have a higher comorbidity burden and a worse functional status, but lower mortality compared with HF-REF patients.

Bendopnea is a symptom described in heart failure (HF) that is related to short-term prognosis; however, its frequency and characteristics in respiratory diseases such as OSAS is still unknown. This study was carried out to evaluate the prevalence of bendopnea in patients with severe obstructive sleep apnea syndrome (OSAS) METHODS: We conducted a study of 95 patients attending a sleep disorders unit with severe OSAS. Bendopnea was considered when shortness of breath occurred within 30s of bending forward. ⋯ One-third of patients with severe OSAS present bendopnea. This symptom is related to a higher prevalence of comorbidities (HF, obesity and other respiratory diseases). It is also related to a higher CT90.
