Sleep disorders especially sleep disordered breathing (SDB) are highly prevalent in patients with established cardiovascular disease. It is unclear whether abnormalities evident in the sleep of patient with cardiovascular disease are secondary to the sleep apnea, the cardiovascular condition, or it may proceed the occurrence of them.

Aim: The aim of this study was to detect the presence of sleep disordered breathing as a co-morbidity in cardiac patients who were to undergo coronary artery bypass grafting (CABG).

Subjects: This study was conducted on thirty multivessel coronary artery disease (CAD) patients that were referred for CABG to the cardiology department.

Methods: All patients were subjected to full history taking, complete clinical examination, standard resting electrocardiogram (ECG), resting transthoracic echocardiogram, coronary angiography (CA), STOP BANG questionnaire, and lastly polysomnography (PSG).

Results: As regard the total obstructive apnea index (OAI) a clear statistical significance was present when comparing all groups of the study (p<0.001). Both the arousal index and the snoring index showed statistical significant results (p<0.001) among patients who were to undergo coronary artery bypass grafting (CABG).

Conclusions: The prevalence of SDB in MVD patients was more than those in the normal population. OSA is tightly linked to cardiovascular disease, and MVD patient with a suspicious history of SDB should be taken in consideration and a PSG study should be done.
