Sleep Architecture in Patients With Primary Snoring and Obstructive Sleep Apnea

Introduction: This study aimed to investigate sleep architecture in patients with primary snoring and obstructive sleep apnea. Methods: In this study, we analyzed polysomnographic data of 391 clients who referred to Sleep Disorders Research Center (SDRS). These people were classified into three groups based on their Apnea-Hypopnea Index (AHI) and snoring; control, Primary Snoring (PS), and Obs...

Is Apnea-Hypopnea Index a proper measure for Obstructive Sleep Apnea severity?

Probability of obstructive sleep apnea in male patients with systolic heart failure and some related factors

Background and Purpose: Sleep breathing disorders have a negative impact on the illness outcome and quality of life in patients with heart failure. This study was conducted to investigate the probability of obstructive sleep apnea in men with heart failure and some related factors. Method: This was a cross-sectional study conducted on 100 male patients with systolic heart failure selected throu...

Advanced age and apnea-hypopnea index predict subclinical atherosclerosis in patients with obstructive sleep apnea syndrome

BACKGROUND Both obstructive sleep apnea syndrome (OSAS) and coronary artery calcification (CAC) are considered to be related with the presence of coronary artery disease (CAD). In this study we evaluate the association between OSAS and presence of subclinical atherosclerosis assessed by tomographic coronary calcium score in patients who had OSAS but no history of known CAD. METHODS Seventy-th...

muller’s maneuver in patients with obstructive sleep apnea

background and objective: numerous anatomical abnormalities or pathological conditions can cause upper airway obstruction in obstructive sleep apnea syndrome (osas). muller’s maneuver (mm) is one of diagnostic modalities investigating the obstruction site in patients with osas. this study aimed to investigate the obstruction sites of patients with osas based on mm. materials and methods: this w...
