Sleep-related respiratory disorders in patients with implantable cardioverter/defibrillator devices--relationship between left ventricular function and respiratory disorder

Abstract

In order to detect sleep related breathing disorders (SRBD), 15 patients (6 with dilated cardiomyopathy [DCM], 9 with coronary heart disease [CHD], mean age 58 +/- 13 years) with implantable cardioverter/defibrillator [ICD] underwent polysomnography. A SRBD could be diagnosed in 27% of cases (n = 4; 3 DCM, 1 CHD). The reduction of the ejection fraction (EF) (normal, mild-to-moderate and severe, respectively) and the quality of sleep-related disturbances (normal, obstructive, and central/periodic) were significantly associated. In addition, in patients with DCM, the reduction of the EF correlated significantly with the amount of nocturnal oxygen-desaturation.
