How does sleep apnea cause cardiovascular disease?
How does sleep apnea cause cardiovascular disease?
Sleep apnea can cause a negative feedback loop whereby it worsens cardiovascular conditions, which then worsen the sleep apnea. OSA affects 30% to 50% of people with high blood pressure and is a risk factor for atrial fibrillation.
What is obstructive sleep Apnoea syndrome?
Obstructive sleep apnea occurs when the muscles that support the soft tissues in your throat, such as your tongue and soft palate, temporarily relax. When these muscles relax, your airway is narrowed or closed, and breathing is momentarily cut off.
How does obstructive sleep apnea affect the heart?
When a person with obstructive sleep apnea (OSA) attempts to breathe, they inhale against a narrowed or closed upper airway. These unsuccessful, forced inhalations can cause substantial changes in pressure within the chest cavity. Over time, these repetitive changes in intrathoracic pressure can damage the heart.
Is obstructive sleep apnea associated with cardiovascular and all cause mortality?
Conclusions: Severe OSA is a strong independent predictor for future cardiovascular and all-cause mortality. CPAP treatment was associated with decrease cardiovascular mortality.
Does obstructive sleep apnea treatment reduce cardiovascular risk?
Clinical cohort studies comparing patients with OSA treated with positive airway pressure (PAP) with untreated patients with OSA have consistently demonstrated lower rates of death, myocardial infarction, and stroke among the treated patients.
What is the difference between sleep Apnoea and obstructive sleep Apnoea syndrome?
Sleep apnoea, or obstructive sleep apnoea syndrome (OSAS), is a condition where your breathing stops for short spells when you are asleep. The word apnoea means without breath – that is, the breathing stops. In the case of sleep apnoea, the breathing stops because of an obstruction to the flow of air down your airway.
Does sleep apnea cause rapid heart rate?
Sleep apnea It occurs when your throat muscles relax, causing your airway to narrow or close. Research shows that sleep apnea increases the risk of irregular heart rate. The sudden drops in your blood oxygen levels raise your blood pressure and strain your cardiovascular system.
What is the difference between cardiovascular disease and heart disease?
Cardiovascular disease, is an umbrella term covering diseases of both the heart (cardio) and blood vessels (vascular) in the body. Heart disease and coronary heart disease are cardiovascular diseases, but so are other diseases affecting blood vessels such as high blood pressure and peripheral artery disease.
