Epidemiologic studies show that sleep apnea increases risks for cardiovascular disease independently of individuals’ demographic characteristics or risk markers i.e., smoking, alcohol, obesity, diabetes, dyslipidemia, atrial fibrillation, and hypertension. Individuals with severe sleep apnea are at increased risk for pulmonary arterial hypertension. The underlying mechanisms explaining associat...

No agreement exists as to the mechanisms responsible for the sympathetic hyperactivity characterizing human obesity, which has been ascribed recently to a chemoreflex stimulation brought about by obstructive sleep apnea rather than to an increase in body weight, per se. In 86 middle-age normotensive subjects classified according to body mass index, waist-to-hip ratio, and apnea/hypopnea index (...
BACKGROUND Patients with obstructive sleep apnea are reported to have a peak of sudden cardiac death at night, in contrast to patients without apnea whose peak is in the morning. We hypothesized that ventricular premature contraction (VPC) frequency would correlate with measures of apnea and sympathetic activity. METHODS Electrocardiograms from a sleep study of 125 patients with coronary arte...
A patient with symptoms of sleep apnea syndrome had signs of congestive cardiac failure. A sleep study fulfilled the criteria for sleep apnea. Features of Cheyne-Stokes respiration coexisted. Management of the cardiac failure by weight loss principally due to diuretic use eliminated the symptoms of sleep apnea.
Obstructive sleep apnea is a common disorder in which the airway repetitively collapses during sleep; patients with sleep apnea are often inattentive and sleepy. This review discusses driving performance and automobile accidents in patients with sleep apnea. Finally, we discuss the effect of therapy upon driving performance and reported accidents in these subjects.
S leep apnea is defined as a sleep disorder with frequent episodes of upper-airway obstruction resulting in hemoglobin oxygen desaturation. The disorder is characterized by periods of breathing cessation (apnea) and periods of reduced breathing (hypopnea). Sleep apnea increases morbidity and mortality, thus making it a condition worthy of investigation.1 Sleep apnea is typically categorized as ...
Sleep apnea is a common disorder associated with obesity and related health problems. Although treatment of sleep apnea may relieve some autonomic symptoms, it is currently unknown whether treatment of sleep apnea is specifically associated with the resolution of orthostatism and syncope. Herein we describe a 73-year-old man who had recurrent episodes of syncope. An extensive work-up, including...
This report seeks to establish the prevalence of sleep apnea in patients with the fragile X mental retardation 1 (FMR1) premutation with and without fragile X-associated tremor/ataxia syndrome (FXTAS) and to determine any correlation between CGG repeat and FMR1 mRNA levels with sleep apnea prevalence. Demographic and medical data from 430 (229 males, 201 females) participants were used in this ...
Abstract Background: There are many risk factors that predispose nurses to sleep disorders. In one hand, sleep disorder affects health and safety of nurses and patients and on the other hand, risk factors of this occupations raise the prevalance of sleep disorders and their complications. Materials and Methods: this study was done cross-sectionally on 190 nurses of Imam Khomeini hospital in ...
