Exercise End-Tidal CO2 Predicts Central Sleep Apnea in Patients With Heart Failure

Original language description

BACKGROUND: Increased CO2 chemosensitivity and augmented exercise ventilation are characteristic of patients with heart failure (HF) with central sleep apnea (CSA). The aim of this study was to test the hypothesis that decreased end-tidal CO2 by cardiopulmonary exercise testing predicts CSA in patients with HF. METHODS: Consecutive ambulatory patients with New York Heart Association II to III HF were prospectively evaluated by CO2 chemosensitivity by rebreathe, cardiopulmonary exercise testing, and polysomnography (PSG). Subjects were classified as having either CSA (n = 20) or no sleep apnea (n = 13) by PSG; a central apnea-hypopnea index (AHI) &gt;= 5 was used to define CSA. Subgroups were compared by t test or Mann-Whitney test and data summarized as mean +/- SD. P &lt; .05 was considered significant. RESULTS: At rest, subjects with CSA had higher central CO2 chemosensitivity (Delta minute ventilation [(V) over dotE]/Delta partial pressure of end-tidal CO2 [PETCO2], 2.3 +/- 1.0 L/mi
