Ventricular-arterial coupling in obstructive sleep apnea.
Arterial elastance (Ea) and systolic elastance are important parameters determining effective functional interaction of heart and vessels. The aims of this study were to (1) compare arterial (arterial elastance index [EaI]) and ventricular (end-systolic elastance [Ees] and end-diastolic elastance [Eed]) elastance in subjects with obstructive sleep apnea (OSA) and patients with treated 'high-ris...
متن کاملArterial Stiffness in Obstructive Sleep Apnea
Obstructive sleep apnea is a very common disease and is associated with an increased risk of cardiovascular disease, cardiac arrhythmia, and stroke. Arterial stiffness is an emerging risk factor and may be involved in the cardiovascular complications of obstructive sleep apnea. The purpose of this review was to demonstrate the correlation between arterial stiffness and obstructive sleep apnea. ...
متن کاملObstructive sleep apnea, masked hypertension, and arterial stiffness in men.
BACKGROUND Obstructive sleep apnea (OSA) is an established cause of hypertension. However, it is not clear whether the frequency of masked hypertension in patients with OSA and whether OSA have an independent role on arterial stiffness taking into account ambulatory blood pressure (BP) monitoring (ABPM). METHODS We evaluated 61 male normotensive participants as determined by casual clinic BP ...
متن کاملSubclinical Left Ventricular Dysfunction in Patients with Obstructive Sleep Apnea
OBJECTIVE We aimed to investigate whether fragmented QRS (fQRS) is associated with subclinical left ventricular (LV) dysfunction in patients with obstructive sleep apnea (OSA). SUBJECTS AND METHODS A total of 141 patients with OSA who had normal LV ejection fraction (LVEF) were included in the study. The fQRS was defined as the presence of an additional R wave, notching of R or S wave or the ...
متن کاملobstructive sleep apnea
sleep apnea, and particularly obstructive sleep apnea, is a common disorder that is characterized by a repetitive, partial or complete cessation of air flow, associated with oxyhemoglobin desaturation and an increased effort to breath. in recent years, orthodontists have been interested and involved in the management of this disorder since it has been shown that oral appliance therapy can be an...
