摘要: Background— In the main analysis of Canadian Continuous Positive Airway Pressure (CPAP) for Patients with Central Sleep Apnea (CSA) and Heart Failure Trial (CANPAP), CPAP had no effect on heart transplant–free survival; however, only reduced mean apnea-hypopnea index to 19 events per hour sleep, which remained above trial inclusion threshold 15. This stratified CANPAP tested hypothesis that suppression CSA below this by would improve left ventricular ejection fraction survival. Methods Results— Of 258 failure patients in CANPAP, 110 130 randomized control group 100 128 sleep studies 3 months later. were divided post hoc into those whose was or not 15 at time (CPAP-CSA suppressed, n=57, CPAP-CSA unsuppressed, n=43, respectively). Their changes tra...
