Abstract

Background and Objectives : Obstructive sleep apnea (OSA) is a common yet an under-diagnosed sleep related breathing disorder associated with many adverse health outcomes. OSA is commonly associated with cardiovascular disorders that include coronary artery disease, heart failure, hypertension, cardiac arrhythmias and stroke. The aim of this study was to investigate the physical characteristics of OSA patients as a screening test for sleep apnea associated cardiovascular disease.
Subjects and Method: One hundred twenty-six adult OSA patients were enrolled in this study. All subjects underwent an overnight polysomnography (PSG) and were determined body mass index (BMI), neck circumstance, waist circumstance, tonsil size, etc. Cardiovascular events, such as hypertension, cardiovascular accident, myocardial infarction, and angina were analyzed. The correlation and multiple regression analysis were conducted to find influential and predictive factors of cardiovascular complications of OSA.
Results: PSG findings, apnea-hypopnea index (AHI), minimal oxygen saturation, and oxygen desaturation index were associated with BMI, neck circumstance, and waist circumstance. Tonsil size was also associated with AHI and oxygen desaturation index. However, PSG results were not associated with cardiovascular accidents of OSA patients. Hypertension was associated with tonsil size, angina was associated with Mallampati score and cardiovascular accident was associated with tonsil size.
Conclusion: Although we cannot find the statistical relation between PSG results and cardiovascular disease, tonsil size and Mallampati score influenced the risk of cardiovascular accident.
