Abstract:
Objective:To explore influence of nasal continuous positive airway pressure (nCPAP)on maximal oxygen uptake (V · O2 max )etc.in patients with chronic congestive heart failure (CHF)complicated moderate-to-severe ob-structive sleep apnea-hypopnea syndrome (OSAHS)and explore its significance.Methods:A total of 83 CHF com-plicated moderate-to-severe OSAHS patients were selected and randomly divided into routine treatment group (n=40)and nCPAP group (n = 43).Both groups were treated for six months.Left ventricular ejection fraction (LVEF),apnea hyponea index (AHI)and V · O2 max were measured and compared between two groups before and af-ter treatment.Results:Compared with routine treatment group after six-month treatment,there was significant re-duction in AHI [(27.5±6.2)vs.(6.8±1.2)],and significant rise in LVEF [(0.45±0.07)vs.(0.48±0.05)]and · V O2 max [(16.5±3.5)ml·kg-1 ·min-1 vs.(19.2±3.4)ml·kg-1 ·min-1 ]in nCPAP group,P <0.05 all.Con-· clusion:The nCPAP can improve ventilation function,heart function and V O2 max in patients with CHF complicated moderate-to-severe OSAHS,who have received basic medication.
