Table 2. Echocardiographic parameters in patients with or without SDB.

	CHF – SDB (n = 68)	CHF + SDB (n = 52)
LVEDD (mm)	67.90 ± 13.20	69.20 ± 9.60
LVEF (%)	42.40 ± 12.80	31.60 ± 11.40*
LAD (mm)	42.20 ± 7.10	50.20 ± 9.30*
RVEDD (mm)	21.80 ± 4.40	28.30 ± 7.00*
mPAP (mm Hg)	36.40 ± 4.10	50.20 ± 9.50*

*P < 0.05. Data are expressed as mean ± SD. CHF: congestive heart failure; LAD: left atrial diameter; LVEDD: left ventricular end diastolic diameter; LVEF: left ventricular ejection fraction; mPAP: mean pulmonary arterial pressure; RVEDD: right ventricular end diastolic diameter; SDB: sleep-disordered breathing.
