Cardiovascular consequences of obstructive sleep apnea.

PURPOSE OF REVIEW: There is an increased awareness of obstructive sleep apnea (OSA) and its potential impact on cardiovascular diseases (CVDs). The number of patients diagnosed with OSA is likely to increase as the obesity epidemic continues to grow. We review recent publications that have examined the links between OSA and CVD. RECENT FINDINGS: The cardiovascular consequences of OSA include hypertension, strokes, atrial fibrillation, and heart failure. It is likely that these are related to OSA-induced changes in endothelial dysfunction, oxidative stress, and systemic inflammation. The mains…

Descartes and His Peculiar Sleep Pattern.

Rene Descartes (1596-1650) was a mathematician, philosopher, and scholar, whose work set a foundation for modern science. Among other interests, he focused on locating the "core and the seat of the soul" and concluded that the pineal gland was such a structure. Recent scientific findings validate Descartes' deep interest in pineal gland, appreciating its role as part of the circadian rhythm system. On the other hand, the biographical information suggests that Descartes had an aberration of the circadian rhythm (delayed sleep phase). Coincidentally, this meant that one of the most important thi…

Obstructive sleep apnoea associated with syringomyelia.

Coexistence of obstructive sleep apnoea and syringomyelia is quite rare. This article discusses three cases of coexisting obstructive sleep apnoea and syringomyelia and looks at the possible mutual influences between the two diseases.

Central sleep apnoea-a clinical review.

Central sleep apnoea (CSA) is characterised by recurrent apnoeas during sleep with no associated respiratory effort. It mostly results from withdrawal of the wakefulness drive in sleep leaving ventilation under metabolic control. A detailed physiological understanding of the control of breathing in wakefulness and sleep is essential to the understanding of CSA. It encompasses a diverse group of conditions with differing aetiologies and pathophysiology. Likewise treatment varies according to underlying aetiology. Some of the conditions such as idiopathic (primary) CSA (ICSA) are relatively rare…

Sleep disorders in multiple sclerosis. Review.

Sleep disorders are common in patients with multiple sclerosis (MS) and play a crucial role in health and quality of life; however, they are often overlooked. The most important sleep disorders in this context are as follows: insomnia, restless legs syndrome, periodic limb movement disorders, and sleep-related breathing disorders (SRBD). It is unclear if MS-related processes (lesions, brain atrophy) can cause symptomatic forms of sleep apnea. MS-related narcolepsy-like symptoms are described in the literature and, in some cases, have resolved with methylprednisolone pulse therapy. Similarly, R…

Morphological predictors of sleep apnoea severity.

BACKGROUND: Obstructive sleep apnoea (OSA) does not always depend on obesity but on a certain morphological configuration. The study objective was to verify a hypothesis about a relation between anthropometric features and OSA occurrence and severity. MATERIALS AND METHODS: The study involved 138 patients, who had reported in Department and Clinic of Otolaryngology, Warsaw Medical University, due to suspected OSA. Each patient underwent morphological evaluation according to visual analogue scales. The assessment involved nasal septum morphology evaluation according to a 4-grade scale, palate …

Diagnostic approaches to respiratory sleep disorders.

Sleep disordered breathing (SDB) comprises a number of breathing disturbances occurring during sleep including snoring, the obstructive sleep apnoea/hypopnea syndrome (OSAHS), central sleep apnoea (CSA) and hypoventilation syndromes. This review focuses on sleep disordered breathing and diagnostic approaches in adults, in particular clinical assessment and overnight assessment during sleep. Although diagnostic approaches to respiratory sleep disorders are reasonably straightforward, they do require a degree of clinical acumen when it comes to assessing severity and management options. Diagnosi…

Sleep-disordered Breathing in Heart Failure.

Sleep-disordered breathing affects over half of patients with heart failure (HF) and is associated with a poor prognosis. It is an under-diagnosed condition and may be a missed therapeutic target. Obstructive sleep apnoea is caused by collapse of the pharynx, exacerbated by rostral fluid shift during sleep. The consequent negative intrathoracic pressure, hypoxaemia, sympathetic nervous system activation and arousals have deleterious cardiovascular effects. Treatment with continuous positive airway pressure may confer symptomatic and prognostic benefit in this group. In central sleep apnoea, th…

Perianesthesia implications of obstructive sleep apnea.

Obstructive sleep apnea (OSA) is a complex medical condition that affects not only the airway but also the cardiopulmonary, endocrine, and central nervous systems. Obstructive sleep apnea can usually be identified with a focused history and physical examination and is commonly associated with obese, middle-aged men with hypertension and glucose intolerance. A high index of suspicion for OSA should arise when reports of loud snoring, nighttime arousal, and acid reflux accompanied by a history of stroke, atrial fibrillation, or congestive heart failure are elicited during a perianesthesia evalua…

Sleep-Related Breathing Disorders and Bruxism.

Obstructive sleep apnea (OSA) syndrome is a sleep-related breathing disorder, due mainly to peripheral causes, characterized by repeated episodes of obstruction of the upper airways, associated with snoring and arousals. The sleep process fragmentation and oxygen desaturation events lead to the major health problems with numerous pathophysiological consequences. Micro-arousals occurring during sleep are considered to be the main causal factor for night jaw-closing muscles activation called bruxism. Bruxism is characterized by clenching and grinding of the teeth or by bracing or thrusting of th…

Sleep Regulates Incubation of Cocaine Craving.

After withdrawal from cocaine, chronic cocaine users often experience persistent reduction in total sleep time, which is accompanied by increased sleep fragmentation resembling chronic insomnia. This and other sleep abnormalities have long been speculated to foster relapse and further drug addiction, but direct evidence is lacking. Here, we report that after prolonged withdrawal from cocaine self-administration, rats exhibited persistent reduction in nonrapid-eye-movement (NREM) and rapid-eye-movement (REM) sleep, as well as increased sleep fragmentation. In an attempt to improve sleep after c…

Sleep-disordered Breathing in Neuromuscular Disease.

Sleep-disordered breathing in neuromuscular diseases is due to an exaggerated reduction in lung volumes during supine sleep, a compromised physiologic adaptation to sleep, and specific features of the diseases that may promote upper airway collapse or heart failure. The normal decrease in the rib cage contribution to the tidal volume during phasic REM sleep becomes a critical vulnerability, resulting in saw-tooth oxygen desaturation possibly representing the earliest manifestation of respiratory muscle weakness. Hypoventilation can occur in REM sleep and progress into non-REM sleep, with conti…

Sleep disturbance in Mowat-Wilson syndrome.

Mowat-Wilson syndrome (MWS) is a multiple congenital anomaly syndrome caused by a heterozygous mutation or deletion of the ZEB2 gene. It is characterized by a distinctive facial appearance in association with intellectual disability (ID) and variable other features including agenesis of the corpus callosum, seizures, congenital heart defects, microcephaly, short stature, hypotonia, and Hirschsprung disease. The current study investigated sleep disturbance in people with MWS. In a series of unstructured interviews focused on development and behaviors in MWS, family members frequently reported s…

Cardiovascular autonomic dysfunctions and sleep disorders.

Animal and human studies have shown that disorders of the autonomic nervous system may influence sleep physiology. Conversely, sleep disorders may be associated with autonomic dysfunctions. The current review describes the clinical presentation, supposed pathogenetic mechanisms and the diagnostic and prognostic implications of impaired cardiovascular autonomic control in sleep disorders. This dysfunction may result from a common pathogenetic mechanism affecting both autonomic cardiovascular control and sleep, as in fatal familial insomnia, or it may be mainly caused by the sleep disorder, as o…
