    Indroduction: Treatment-emergent central sleep apnea(complex sleep apnea) has been observed in approximately 3,5%-20% of patients treated with CPAP for obstructive sleep apnea Aims and objectives: To identify facrors that influence the evolution of treatment-emergent central sleep apnea Patients and methods: 40 patients diagnosed with treatment-emergent central sleep apnea in a general hospital were followed up using data from the CPAP memory cards and repeated clinical examinations.95% were men, with mean age:61±9.7 years, Body Mass Index:29.1±4.2 and polysomnography Apnea Hypopnea Index(AHI):60.9±27.2 Results: 2 to 6 months after the initiatin of treatment with CPAP 45.9% of patients had a residual AHI<5, whereas only 8% had residual AHI>15. There was a further resolution of treatment-emergent central sleep apnea after the initial 6 months of follow-up. Changes in the initial CPAP pressure settings were not found to be related to residual AHI improvement. Conclusions: Improvement in residual AHI of treatment-emergent central sleep apnea patients beyond the initial 6 months warrants further investigation.Changes in the initial CPAP pressure settings are not correlated to improved residual AHI

    The aim of this study is to investigate the occurrence and mechanism of Cheyne-Stokes breathing pattern in patients with heart failure.Fifty-six patients who performed polusomnography sleep testing at National Center of Cardiovascular Diseases Fuwai Hospital from March to May in 2015. We divided them into chronic heart failure (CHF) group and non-CHF group.The occurrences of sleep apnea in two groups were high. In CHF group (n = 11) , there were 10 patients with apnea hypopnea index (AHI) > 5; and their AHI was 23.93 ±14.63. In non-CHF group (n = 45), there were 33 patients whose AHI > 5; and their AHI was 16.20 ± 18.76. The ratio of center sleep apnea to all gross sleep apnea ratio in CHF group was higher than that in non-CHF group (80.21% ± 30.55% vs 27.16% ± 35.71%, P < 0.01 ).Based upon the new theory of holistic integrative physiology and medicine, we explain the mechanism of circulatory dysfunction induce the oscillation breathing in patients with CHF. The sleep apnea and C-S respiration in CHF should be called circulatory sleep apnea, rather than central sleep apnea.

    The risk factors, clinical manifestations, pathophysiology, diagnosis and treatment options for central sleep apnea and Cheyne-Stokes respiration in patients with heart failure are highlighted in this review. The effectiveness and prospects of therapeutic approaches are discussed: CPAP therapy, adaptive servo ventilation, transvenous stimulation of the phrenic nerve.
