Guarding Your Heart With Proper Treatment
Sleep apnea, a common yet serious sleep disorder, is characterized by intermittent pauses in breathing during sleep, leading to disrupted rest and a range of severe health consequences. At the Center for Dental Sleep Health in Nashua, NH, sleep dentist Dr. Stephen Ura understands that sleep apnea is more prevalent than ever, affecting approximately 25 million adults in the United States.
If sleep apnea is left untreated, it can significantly impact various health aspects, especially cardiovascular health. The connection between sleep apnea and heart health is crucial, as untreated sleep apnea can lead to life-threatening heart conditions.

The Link Between Sleep Apnea and Cardiovascular Health
Sleep apnea is more than just a disruption of breathing patterns during sleep; it’s closely linked to cardiovascular health. This connection is vital to understanding the full scope of its impact on overall well-being.
Intermittent Hypoxia and Hypercapnia
One of the primary mechanisms through which sleep apnea affects cardiovascular health is intermittent hypoxia (low oxygen levels) and hypercapnia (elevated carbon dioxide levels). During apnea episodes, oxygen levels in the blood drop, and carbon dioxide levels rise, triggering the body to respond.
In response to low oxygen levels, the sympathetic nervous system is activated, leading to an increase in heart rate and blood pressure. These fluctuations in oxygen and carbon dioxide can have profound long-term effects on cardiovascular health.
Sympathetic Nervous System Activation
The sympathetic nervous system, known as the “fight or flight” system, prepares the body to respond to stress. In individuals with untreated sleep apnea, this system is repeatedly activated throughout the night due to drops in oxygen levels. Chronic activation can result in sustained high blood pressure, a significant risk factor for cardiovascular disease.
Inflammation and Oxidative Stress
Sleep apnea is associated with increased levels of inflammation and oxidative stress in the body. Repeated breathing disruptions trigger an inflammatory response, leading to the release of pro-inflammatory cytokines. Chronic inflammation can damage blood vessel walls and contribute to the development of atherosclerosis, a key factor in cardiovascular disease.
Oxidative stress, caused by an imbalance between free radicals and antioxidants, can further damage blood vessels, exacerbating the risk of cardiovascular complications.
Cardiovascular Consequences of Untreated Sleep Apnea
Hypertension
Hypertension, or high blood pressure, is one of the most well-documented consequences of untreated sleep apnea. The cyclical drops in oxygen levels trigger the release of stress hormones, leading to elevated blood pressure. Over time, this can lead to chronic hypertension, significantly increasing the risk of heart disease, stroke, and other cardiovascular events.
Coronary Artery Disease (CAD)
Coronary Artery Disease (CAD) is another major concern. Frequent breathing interruptions can cause plaque buildup in the arteries (atherosclerosis), reducing blood flow to the heart. This can ultimately result in heart attacks and angina.
Arrhythmias
Sleep apnea is also associated with an increased risk of arrhythmias, such as atrial fibrillation. Disruptions in normal breathing patterns can lead to irregular heart rhythms, which may seriously affect cardiac function. Individuals with sleep apnea are also at a greater risk of heart failure, as the condition places additional strain on the heart’s pumping ability.
Screening and Diagnosis of Sleep Apnea
Accurate diagnosis of sleep apnea typically involves specialized testing.
- Polysomnography (PSG): This comprehensive overnight sleep study is conducted in a specialized sleep center.
- Home Sleep Apnea Testing (HSAT): This test uses portable devices to monitor sleep at home.
These tests are often ordered by healthcare professionals specializing in sleep medicine, pulmonology, or otolaryngology, and in some cases, by dentists with expertise in dental sleep medicine like Dr. Ura.
Treatment Approaches
The primary treatment for sleep apnea is Continuous Positive Airway Pressure (CPAP), which delivers continuous airflow through a mask to keep the airway open. While CPAP is highly effective, some individuals find compliance challenging.
Oral appliances like mandibular advancement devices (MADs) and tongue-retaining devices (TRDs) may be recommended in such cases. These devices reposition the jaw or tongue to maintain an open airway during sleep.
Lifestyle modifications also play a critical role in managing sleep apnea. Weight management, dietary adjustments, regular exercise, and avoiding sleep-disrupting habits can significantly improve sleep quality and reduce the severity of sleep apnea.
Interdisciplinary Care and Collaboration
The treatment of sleep apnea often requires a multidisciplinary approach. Specialists from various fields, including sleep medicine, cardiology, pulmonology, and dentistry, collaborate to develop comprehensive treatment plans tailored to each patient’s unique needs. This integrated approach ensures all aspects of the condition are effectively addressed.
Regular monitoring and follow-up are essential components of successful sleep apnea management. Periodic assessments of sleep apnea severity and its impact on cardiovascular health guide adjustments to treatment plans as necessary, ensuring optimal outcomes for patients.
Frequently Asked Questions
Are there any risk factors that increase the likelihood of developing sleep apnea-related cardiovascular problems?
Yes, certain factors can heighten the risk of developing sleep apnea-related cardiovascular problems. These may include a family history of cardiovascular disease, smoking, excessive alcohol consumption, and pre-existing conditions like diabetes and obesity.
Can sleep apnea lead to other health complications aside from cardiovascular issues?
Yes, untreated sleep apnea can have a wide range of health consequences. These may include daytime sleepiness, impaired cognitive function, mood disorders, and an increased risk of accidents due to drowsiness.
Is there a connection between sleep apnea and stroke risk?
Yes, studies have shown a link between sleep apnea and an increased risk of stroke. The intermittent drops in oxygen levels and the resulting physiological stress on the body can contribute to the development of vascular issues that increase the likelihood of stroke.
Can lifestyle changes alone effectively manage sleep apnea and reduce its impact on cardiovascular health?
In some cases, adopting a healthier lifestyle, including weight loss, regular exercise, and avoiding smoking and excessive alcohol, can lead to significant improvements. However, for many individuals, a combination of lifestyle changes and medical interventions is necessary.
