| • Severe LV dysfunction (mean LVEF ∼20%) |
| • Cause of heart failure is predominantly coronary artery disease |
| • Sleep breathing disorder is a consequence of the heart disease. |
| • Treatment may include modalities other than CPAP including oxygen, theophylline, nasal ventilation |
CHF = congestive heart failure; LVEF = left ventricular ejection fraction; CPAP = continuous positive airway pressure.
