Unforeseen lethal risks associated with sleep apnea
Obstructive Sleep Apnea (OSA), a condition that affects an estimated 1 billion people worldwide, has been linked to a higher risk of sudden death. A recent study found that people with OSA are twice as likely to die suddenly from all causes compared to those without the disorder [1].
The primary focus for effective treatments and interventions is managing the airway obstruction and improving overall cardiovascular health.
Continuous Positive Airway Pressure (CPAP) Therapy, the most widely recommended and effective treatment for moderate to severe OSA, works by delivering constant air pressure to keep the airways open during sleep, preventing apnea episodes and the associated oxygen desaturation [1][2][4]. Studies have shown that consistent CPAP use significantly lowers the risk of death by reducing complications such as cardiovascular disease, stroke, hypertension, and diabetes, all of which are conditions that contribute to sudden death risk in OSA patients [1]. CPAP improves oxygen levels, blood flow, and reduces inflammation and stress on the body, which helps mitigate long-term damage to the heart and brain [1].
Mandibular advancement devices can be effective alternatives to CPAP, especially for mild to moderate OSA. These devices help reposition the jaw to keep the airway open [2]. They are considered comparably effective in some cases.
Lifestyle modifications play a crucial role in managing OSA. Weight loss in overweight individuals is strongly recommended, as obesity worsens OSA and related cardiovascular risk factors [2]. Avoidance of alcohol, smoking, and sedative medications that relax the airway muscles also helps reduce apnea severity and associated risks [2].
In select patients, surgical procedures such as tonsillectomy or uvulopalatopharyngoplasty (UPPP) may be performed to reduce airway obstruction [2][5]. Surgical treatment has been linked to reductions in arrhythmic events (like atrial fibrillation), which are a concern in OSA patients and contribute to sudden cardiac death risk [5].
Neurostimulation therapies, such as hypoglossal nerve stimulation, show promise in improving airway patency [2]. Physical exercises targeting throat muscles may provide some benefit but require further evidence [2].
A modest increase in daily exercise can reduce the severity of OSA. Even a small number of polluting particles in the air can raise the risk of sleep apnea by 60%. Future studies should examine the link between OSA and death in these populations.
The study also confirmed that OSA increases the risk of developing certain cardiovascular conditions like hypertension, coronary artery disease, and congestive heart failure. Chronic OSA increases the risk of various heart problems, including high blood pressure, stroke, heart failure, coronary artery disease, and irregular heartbeat.
In addition to these treatments and interventions, simple measures such as putting an air purifier in your bedroom may help relieve sleep apnea symptoms. Losing weight if overweight, avoiding alcohol, tranquilizers, and sleeping pills, and sleeping on one's side or stomach instead of the back can also help relieve OSA.
Future studies are needed to identify treatments and interventions that can improve the survival of OSA patients and further reduce the risk of sudden death.
