ABSTRACT
BACKGROUND:
Congestive heart failure (CHF) patients often present with obstructive and central sleep apnea occurring concurrently within the same night. This study assessed the efficacy of, and improvements associated with, the use of adaptive servo-ventilation (ASV) in CHF patients with all types of sleep apnea. We hypothesized that ASV would be effective at reducing sleep apnea and improving both cardiac status and quality of life.METHODS:
Eleven male patients with stable CHF and sleep apnea (apnea/hypopnea index (AHI) >15 events/h) were treated with 6 months optimized ASV and compared to 8 patients not receiving ASV. At baseline, both groups were comparable for New York Heart Association class, left ventricular ejection fraction (LVEF), plasma Brain Natriuretric Peptide (BNP) concentrations and AHI. All patients were receiving optimal medical therapy.RESULTS:
At 6 months ASV significantly reduced AHI (mean (SD), baseline 49.0 (35.1) v ASV 7.6 (14.6); p=0.001) and LVEF was increased (median (inter-quartile range), treatment group +5.7 (1.6-9.5) v comparison group -4.0 (-8.9-+4.6)% respectively; p=0.04) but not BNP (p=0.59). The energy/vitality score of the SF-36 quality of life questionnaire was also improved at 6 months (treatment group +10 (5-35) v comparison group -12 (-18-+10); p=0.005).CONCLUSION:
ASV effectively reduces all types of sleep apnea. Six months of use is associated with improvement in LVEF and aspects of quality of life.
