CRT14: SLEEP APNEA IN PATIENTS TREATED WITH CARDIAC RESYNCHRONIZATION THERAPY

Purpose of the study to assess the SDB in pts with advanced chronic heart failure (CHF) treated with CRT in 3 months follow-up. Methods: The study group consisted of 17 pts (3F, 14M, aged 53±9 years) with CHF at NYHA class III, EF 5 and≤15) or Apneic (Est.AHI >15). The Est.AHI as well as the percentage of pts qualified for Normal, Borderline or Apneic class from baseline recordings and after 3 months follow-up were calculated. Results Mean value of the Est.AHI before BIV implantation was 7,5±4,6 (range: 23,3-0) and decreased significantly in 3 months follow-up having then the value of 4,6±5,5 (range: 13,0-0); p=0,003. After 3 months follow-up the total and significant reduction of Apneic class and the tendency to increase of Borderline class were observed.

CRT therapy may have beneficial influence on sleep disordered breathing.
