BACKGROUND: The aim of this study was to determine the relationship between body
position, pulmonary function (PF) and bronchial blood flow (Qaw) in a group of heart failure
(HF) and control subjects. METHODS: Thirty-six subjects were studied: 24 stable,
ambulatory HF patients (HF: LVEF= 27±6%, age= 65±9 yr) and 12 age-and sex-matched
controls (CTRL: LVEF= 60±7%, age= 62±8 yr). Measures of Q˙ aw (soluble gas method) and
PF were collected upright and following 30min in the supine position. RESULTS: Q˙ aw was …
