Noninvasive Ventilation for Chronic Heart Failure

The effects of home noninvasive ventilation on renin-angiotensin system (RAS), kallikrein-kinin system (KKS) and cardiac remodeling in patients with chronic stable heart failure have not been reported. This project aims to clarify the efficacy and safety of home non-invasive ventilation in patients with chronic heart failure complicated with sleep-disordered breathing. First, patients with chronic stable heart failure were selected and monitored by polysomnography. Patients with sleep apnea hypopnea syndrome (SAHS, AHI≥15) were randomly divided into two groups: the treatment group was treated with non-invasive ventilator at home (≥5h/ night); The control group was only given routine treatment. After 6 months of follow-up, the effects of sleep disordered breathing and noninvasive ventilation on RAS, KKS, cardiac remodeling and function and cardiovascular adverse events in patients with chronic heart failure were evaluated. The results are helpful to further reveal the role of sleep disordered breathing in the occurrence and development of chronic heart failure, and provide a new diagnosis and treatment strategy for chronic heart failure.
