BACKGROUND In men with heart failure, nocturnal rostral fluid shift is associated with an overnight increase in the neck circumference (NC) and with severity of obstructive sleep apnea. Because the prevalence of obstructive sleep apnea is lower in women than in men with heart failure, we hypothesized that less fluid would shift into the neck in association with less severe obstructive sleep apn...

399 B oth sleep apnea and congestive heart failure are common disorders. However, systolic heart failure appears to be the most common cause of central and perhaps obstructive sleep apnea. Obstructive sleep apnea is also common in isolated diastolic heart failure and may contribute to the progression of left ventricular remodeling and perhaps play a causative role. 1,3-6 However, prevalence and...

UNLABELLED Therapeutic decisions in patients with sleep apnea (eg, adjustment of continuous positive airway pressure [CPAP]) depend on differentiating central from obstructive apnea. Obstructive apnea is defined by cessation of airflow in the presence of continued respiratory effort, which is conventionally inferred from chest wall movement or intrathoracic pressure swings. Cardiogenic oscillat...

objectives: obstructive sleep apnea (osa) can lead to various cardiovascular disorders (cvd) such as hypertension. there is no documented data about this relationship among the iranian population. the aim of this study was to obtain comprehensive information about the severity of osa as a cause of cvd and its relationship with other important risk factors. materials and methods: in this cross s...

background and objective: obstructive sleep apnea (osa) is defined as a sleep disordered breathing due to partial or complete obstruction of upper airways. this study aimed to investigate treatment outcomes and clinical complications among patients with osa who underwent upper airway surgery in clinical settings. materials and methods: all patients undergone upper airway surgery for osa were ca...

background and objective: obstructive sleep apnea (osa) is a disease with serious consequences. many portable devices have been developed to overwhelm some of limitations in the accessibility of the gold standard test for osa, polysomnography (psg). this study aimed to determine diagnostic accuracy of a portable sleep apnea screener against psg in patients of a sleep clinic. materials and metho...

overlap syndrome, which is known as the coexistence of chronic obstructive pulmonary disease (copd) and obstructive sleep apnea (osa), was first defined by flenley. although it can refer to concomitant occurrence of any of the pulmonary diseases and osa, overlap syndrome is commonly considered as the coexistence of osa and copd. this disease has unique adverse health consequences distinct from ...

conclusions we assessed polysomnographic parameters of ahi, odi, laso2 and mean nocturnal spo2 levels, which are especially important in the association between nafld and osas. we think that it is necessary to be attentive regarding nafld development and progression in patients with osa whose nocturnal hypoxia is severe. patients and methods in this study, between december 2011 and december 201...

We describe a child with sickle cell anemia and multiple ischemic infarctions who was found to have severe obstructive sleep apnea and hypoxemia, secondary to adenotonsillar enlargement. The apnea-associated hypoxemia likely contributed to the development of the strokes in this child. Moreover, because stroke in patients with sickle cell anemia, and maximal tonsillar enlargement (the most commo...

Sleep disorders are common during the clinical course of the main neurodegenerative diseases. Among these disorders, obstructive sleep apnea has been extensively studied in the last decade and recent knowledge regarding its relationship with the neurodegenerative process points a bidirectional relationship. Neurodegenerative diseases can lead to functional changes in the respiratory system that...
