Obstructive sleep apnea and resistant hypertension: a case-control study
The Dangers of Uncontrolled Sleep Apnea | Johns Hopkins Medicine
Disrupted sleep could contribute to a higher risk of death, a study suggests. The phenomenon is a normal part of sleep, but when it accounts for a larger proportion of sleep it can become a problem, the authors suggested. The study, published in the European Heart Journal, saw researchers examine sleep data from more than 8, men and women. The participants, aged 64 to 83, were followed up for between six and 11 years.
Obstructive Sleep Apnea
A new study has shown a clear link between the frequency and duration of unconscious wakefulness during night-time sleep and an increased risk of dying from diseases of the heart and blood vessels, and death from any cause, particularly in women. The study of men and women found that female adults who experienced unconscious wakefulness most often and for longer periods of time had nearly double the risk of dying from cardiovascular disease during an average of between 6 and 11 years' follow-up when compared to the risk in the general female population. The association was less clear in men, and their risk of cardiovascular death increased by just over a quarter compared to the general male population. Unconscious wakefulness, also known as cortical arousal, is a normal part of sleep. It occurs spontaneously and is part of the body's ability to respond to potentially dangerous situations, such as noise or breathing becoming obstructed.
Central sleep apnea CSA or central sleep apnea syndrome CSAS is a sleep -related disorder in which the effort to breathe is diminished or absent, typically for 10 to 30 seconds either intermittently or in cycles, and is usually associated with a reduction in blood oxygen saturation. In a healthy person during sleep, breathing is regular so oxygen levels and carbon dioxide levels in the bloodstream stay fairly constant:  After exhalation, the blood level of oxygen decreases and that of carbon dioxide increases. Exchange of gases with a lungful of fresh air is necessary to replenish oxygen and rid the bloodstream of built-up carbon dioxide. Oxygen and carbon dioxide receptors in the body called chemoreceptors send nerve impulses to the brain, which then signals for reflexive opening of the larynx enlarging the opening between the vocal cords and movements of the rib cage muscles and diaphragm. These muscles expand the thorax chest cavity so that a partial vacuum is made within the lungs and air rushes in to fill it.
