Keywords: OSAS, diastolic dysfunction, cardiac co-morbidity

Aim: Obstructive sleep apnea syndrome (OSAS) could have an influence on myocardial functions even before the development of hypertension and the other cardiovascular diseases. The purpose of this study was to evaluate the left ventricular functions of the patients with OSAS excluded from the diagnosis of HT and other cardiovascular diseases.

Material and Methods: Forthy patients diagnosed as OSAS with polysomnographic (PSG) analysis and in whom coronary artery disease was ruled out with myocardium perfusion scintigraphy were included in the study. Control group consisted of 16 volunteers in whom OSAS was excluded with PSG analysis. All patients underwent two dimensional trans-thoracic echocardiographic examinations. Differences between patient and control group with regard to echocardiograhic parameters and relation with PSG finding and echocardiographic parameters were evaluated.

Results: A total of 56 participants enrolled the study. There were no significant differences between patient and control group with regard to age, sex, smoking habits and body mass index. When the echocardiographic parameters were evaluated; left ventricular internal dimension at the end of diastole (LVIDD), left atrial diameter (LAD), aortic dimension (AD) and stroke volume (SV) were significantly higher in patient group compare to control group (p=0.01, p=0.008, p=0.006, p=0.03 respectively). Additionaly, there was a significant positive correlation between the desaturation period spent under 90% and LVIDD (p:0.02, r=0.347) and SV (p=0.01, r=0.376).

Conclusion: Left ventricular diastolic dysfunction seems to be associated with the desaturation time spent under %90 in patients with OSAS. Patients in whom diastolic dysfunction was detected by echocardiographic examination without any other cardiac disease should be evaluated for OSAS. s not useful to predict PE patients in this study
