Sleep Apneas Effects On The Cardiovascular System

Sleep Apnea and its Impact on the Heart

The repetitive pauses in breathing that characterize sleep apnea can stress and potentially damage not only the heart, but the whole cardiovascular system. While researchers are continuing to learn about the ways in which sleep apnea affects the cardiovascular system and contributes to heart disease, several biological pathways have been suggested.

Understanding And Improving Heart Rate

Having a healthy heart matters but what can you do to keep your heart rate in a healthy range? Tracking your heart rate;with a heart rate monitor is the best way to evaluate your sleeping heart rate. These tools provide you with important heart rate data that can help determine long-term health outcomes.

You can also use the old fashioned method of measuring your pulse rate with your fingertips just make sure youve had ample time to rest after a stressful event or a bout of exercise. Measuring your pulse in cooler, drier temperatures can also ensure a more accurate reading, as heat and humidity can increase heart rate.

Electrocardiograms;are another test that can be used to measure the heart. Often administered by a cardiologist, these can be especially useful for people suffering from irregular heart beats, chest pain, heart palpitations, or other heart-related issues. This is a fast, simple method to measure the electrical activity of the heart in its resting state.

When it comes to improving your heart rate and aiming for a healthy range, physical activity is key. Regularly meeting your target heart rate while exercising helps strengthen your heart and improve your aerobic capacity, says Harvard Health Publishing. While this is one of the most effective ways to lower your sleeping heart rate and increase your maximum heart rate, its best to proceed with caution.

Sleep For People With Heart Disease

Because sleep deprivation can harm the heart, its important for people with cardiovascular problems to make getting good sleep a priority. Some evidence even indicates that improving sleep may reduce the likelihood of heart attacks or other cardiovascular problems in people who are otherwise at high risk.

Unfortunately, some heart problems can interfere with sleep. For example, diabetes can cause frequent nighttime urination, and other cardiovascular disorders may create chest discomfort when trying to get to sleep. Worry and anxiety about heart health can also make it hard to wind down and fall asleep normally.

Because numerous factors can influence both sleep and cardiovascular health, its most helpful to talk with your doctor about heart-healthy sleep. A doctor can help develop a specific plan to improve your sleep while also addressing other lifestyle factors, such as diet and exercise, that are important for your heart and overall wellness.

Sleep And High Blood Pressure

Several studies have shown that people with obstructive sleep apnea are at a much greater risk of having high blood pressure. OSA causes your oxygen level to drop. Your heart beats faster due to the lack of oxygen. This causes your blood pressure to rise. Over time, this can lead to an ongoing increase in blood pressure. It is important to treat high blood pressure since it is a proven cause of other forms of cardiovascular disease. This includes heart attack, heart failure and stroke.

But treating high blood pressure may not be enough. When high blood pressure does not respond well to treatment, it is often due to the presence of untreated sleep apnea. Once the OSA is treated, then the high blood pressure tends to improve as well. It is vital for your doctor to determine if a sleep disorder such as OSA is a factor in your high blood pressure.

Why Might Osa Increase A

Can Sleep Apnea Cause Rapid Heart Rate

The researchers are unable to describe the precise mechanisms that drive the link between OSA and increased risk of A-fib, but senior author Dr. Richard S. Leung, of the University of Toronto in Canada, has some theories:

âGreater endothelial dysfunction, higher propensity to develop pulmonary and systemic hypertension and impaired heart rate responses to autonomic challenges in women with OSA may explain these findings,â he says, âbut further studies are needed to confirm this finding and understand the potential mechanisms.â

The researchers admit that there are some limitations to their study. For example, they did not have data on patientsâ adherence to treatment with continuous positive air pressure, which is the primary therapy for patients with OSA.

What is more, the team was unable to determine whether or not patients were being treated for high blood pressure.

Why Does Sleep Apnea Affect The Heart

Yet, researchers have yet to fully understand exactly how sleep apnea could lead to troubles with heart health. The sleep disorder is also strongly associated with obesity, stroke and type II diabetes, all health troubles that can play into the development and worsening of cardiovascular problems.;However, the studies are stacking up. Even if you separate out the other risk factorsstress, metabolic syndromesleep apnea is still an independent risk factor for cardiovascular problems, says Mostafavi.

A joint scientific statement from the American Heart Association and the American College of Cardiology outlines some of the biological reasons that could explain sleep apneas influence on cardiovascular disease and death, even when those other conditions are taken into account;^7.

In a typical, non-disordered nights sleep, a persons blood pressure, heart rate and respiration dip and climb as they enter and leave different stages of sleep. But in sleep apnea, those changes are more dramatic and tied to the duration of apnea episodes instead of sleeps natural rhythms. This disruption of the sleep cycle sets off a host of changes throughout the body;^8.

A person with sleep apneas blood oxygen levels can drop to less than 60 percent. Normally these levels are at 95 to 100 percent. This hypoxemia triggers a number of changes. Blood vessels constrict and increase blood pressure, causing spikes that can reach 240/130.

Sleep Apnea Obesity And Heart Disease

Research suggests that obesity may play an important role in the development of both sleep apnea and heart disease. It is important to keep in mind that sleep apnea alone, with or without obesity, can increase the risk for heart disease. Sleep apnea and obesity independently increase the risk of health conditions that negatively affect heart health, like hypertension , unhealthy cholesterol levels, and diabetes.

Obesity is a common cause of sleep apnea, often related to increased deposits of fat in the neck that narrow or block the upper airway during sleep. Researchers have found that even a 10% increase in body weight increases the risk of OSA by six-fold. While 60 to 90% of people with sleep apnea also have obesity, only around 30% of people diagnosed with obesity have sleep apnea.

Changes In Pressure Within The Chest

When a person with obstructive sleep apnea 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. Intrathoracic pressure changes can lead to atrial fibrillation , problems with blood flow to the heart, and even heart failure.

Treating Sleep Apnea To Reduce The Risk Of Heart Disease

Sleep apnea linked to heart disease and stroke

Talking to a doctor about sleep apnea is an important step that anyone can take to protect their heart health. If a person is diagnosed with sleep apnea, treatments are often effective. Treatment for sleep apnea depends on the type of sleep apnea detected and may include:

  • Lifestyle changes: Doctors may begin by informing patients about lifestyle changes that may reduce the severity of this condition. Weight loss, exercise, limiting alcohol, quitting smoking, and even changing your sleeping position may be helpful.
  • Positive airway pressure devices: PAP devices pump air through the airway, preventing the upper airway from collapsing during sleep.
  • Mouthpieces and oral appliances: Oral appliances reduce disordered breathing by changing the position of the jaw, tongue, or other part of the body thats constricting the airway.
  • Mouth and throat exercises: Depending on the cause of a persons sleep apnea, special exercises of the mouth and throat may help tone these muscles, making them less likely to interfere with breathing during sleep.
  • Surgery: Surgery for sleep apnea may involve changing parts of the body that cause airway constriction or implanting devices that causes tightening of the muscles around the airway.

Sleep And Coronary Artery Disease

People with obstructive sleep apnea have been shown to have higher rates of coronary artery disease . There are two main reasons why this may occur:

  • OSA increases the risk for high blood pressure, which is a known cause of CAD.
  • The events that occur during OSA can put great stress on the heart and worsen existing disease.
  • CAD limits the flow of blood due to narrow arteries. This prevents the right amount of oxygen from reaching the heart. Sleep apnea also causes the blood oxygen level to drop during pauses in breathing. This leads to a rise in the heart rate and blood pressure. An extra strain is put on the heart. The amount of oxygen sent to the heart decreases at the time when the heart needs more oxygen. Studies have shown that the presence of OSA increases the risk of death from CAD. But if the sleep apnea is treated, death due to CAD is reduced.

    How Sleep Apnea Affects The Heart

    Poor-quality sleep and heart disease are connected.

    We’ve all heard stories about super snorers, whose snorts and snores rattle windows and awaken the neighbors. Many of these people suffer from sleep apnea. In this condition, the airway becomes blocked, or the muscles that control breathing stop moving. Either way, breathing stops… and then resumes with a gasp. In the worst cases, this can happen hundreds of times every night.

    Because sleep apnea sufferers are constantly awakened, they have poor-quality sleep and feel exhausted all day. They may also suffer from poor cardiovascular health. The sleep disorder is found in 47% to 83% of people with cardiovascular disease, 35% of people with high blood pressure, and 12% to 53% of people with heart failure, atrial fibrillation , and stroke. Researchers estimate that untreated sleep apnea may raise the risk of dying from heart disease by up to five times.

    Heart Rate And The Severity Of Osahs

    In the 62 patients, before nCPAP therapy, heart rate over the 24-h period was positively correlated with AHI during sleep . It was also positively correlated with the percentage time of arterial O 2 saturation <90% during sleep . The degree of the reduction in heart rate after nCPAP therapy was positively correlated with the degree of the decrease in AHI during sleep . It was also positively correlated with the degree of the decrease in percentage time of arterial O 2 saturation <90% during sleep .

    Among the 15 patients whose heart rate was measured for 2 days before nCPAP treatment, heart rates did not differ significantly between the first and the second 24-h interval . This result was unaltered if the two patients who were receiving a beta-blocker were excluded from the analysis.

    Isnt Sleep Apnea Just A Fancy Name For Snoring

    Not at all. Snoring is that annoying sound that occurs when air passes relaxed tissues in your throat as you sleep. Sleep apnea is a disorder in which a persons breathing repeatedly starts and stops during sleep.;Not everyone who snores has sleep apnea, but many who have sleep apnea do snore regularly and loudly. One in five adults suffers from at least mild sleep apnea; it afflicts more men than women.;The most common type is obstructive sleep apnea , in which weight on the upper chest and neck contributes to blocking the flow of air. A less-common type, central sleep apnea , occurs when the brain fails to send regular signals to the diaphragm to contract and expand. CSA has been associated with brain stem stroke.

    Sleep And Type 2 Diabetes

    Type 2 diabetes is a chronic condition in which the level of blood sugar, also known as blood glucose, is too high due to the bodys inability to process sugar properly. Excess blood glucose damages blood vessels, negatively affecting cardiovascular health. People with diabetes are twice as likely to die from heart disease or stroke than people without this condition.

    Many factors affect blood sugar, but studies have found that a lack of sleep worsens glucose metabolism. Poor sleep is associated with prediabetes, a a type of glucose intolerance that does not meet the parameters for diabetes. People already diagnosed with diabetes who have insufficient or restless sleep may have a harder time controlling their blood sugar. Impaired sleep may also worsen the hardening of arteries in people with type 2 diabetes.

    Sleep And Heart Attacks

    A heart attack, also known as myocardial infarction, happens when the flow of blood to the heart gets blocked. Heart attacks can be fatal because of the damage that occurs when the heart does not get enough oxygen.

    Sleep deprivation heightens the risk of heart attacks. In one study, people sleeping less than six hours per night had a 20% higher chance of a heart attack. While the NREM sleep stage helps the heart slow down and recover, REM sleep involves heightened stress and activity. Insufficient sleep can throw off the balance of these stages, increasing heart attack risk.

    Sleep interruptions have also been linked to the potential for heart attacks. Because both heart rate and blood pressure can abruptly spike upon awakening, frequent sleep disruptions can cause cardiac stress and may induce a heart attack.

    There are numerous people who complain about waking up with a fast-beating heart. While some think this isnt anything to worry about, there are studies that link waking up with an irregular heartbeat to sleep apnea. Sleep apnea is a very common sleeping disorder that is very alarming. In fact, a;report by the National Sleep Foundation said that there are over 18 million adults in America that are diagnosed with this condition. Also, that it can be found in all age groups and for both sexes. The report also shows that a minimum of 3% of children are suspected of having sleep apnea and even up to 20% of children who snore have a higher chance of getting the condition.

    Having A Racing Heart Chest Pain And Dizziness

    A racing heart, chest pain, and dizziness are warning signs of a heart attack. If you or someone else are experiencing these symptoms, call 911 or your local emergency services right away.

    Medical emergency

    A heart attack is a medical emergency and needs immediate medical treatment. Go to the nearest emergency room if you experience these symptoms.

    Your doctor will begin by asking about your symptoms and performing a physical examination. Theyll listen to your heart and check for signs of conditions that can cause a racing heart, such as an enlarged thyroid.

    Your doctor may also order one or more of the following tests:

    Youd Be Shocked To Know Just All The Ways That Sleep Apnea Can Harm The Heart

    If youve ever wondered why periods of stopped breathing can be so dangerous to the cardiovascular system even though the heart doesnt actually stop beating, youre about to find out.

    Sleep apnea is usually the obstructive type. This means that while youre asleep, the structures and tissues of the upper airway collapse.

    This may partially or completely obstruct the passage of inhaled air coming through.

    If its a complete obstruction, the person will stop breathing.

    However, the brain eventually senses a drop in oxygen levels, and rouses the sleeper just enough to unrelax the airway tissues and allow for a deep breath.

    Then the process starts all over again all through the night.

    Sleep apnea affects all ages.

    What this all means is that the oxygen levels in the body are dropping , then rising with recovery breaths, then falling again, back and forth.

    Recurrent desaturation and re-saturation and recurrent arousals leads to fluctuations in pleural pressure and strains the heart, and can cause bradycardia and then tachycardia, says Dr. Nancy Foldvary-Schaefer, DO, MS, and Director, Sleep Disorders Center, Cleveland Clinic.

    • Bradycardia: abnormally slow heartbeat
    • Tachycardia: abnormally fast heartbeat

    The heart should rest in sleep, but in the presence of significant OSA, the heart is actually working harder than it should be, says Dr. Foldvary-Schaefer.

    Sleep Tips For People With Heart Problems

    While theres no silver bullet solution, certain tips can often help people with heart problems get better sleep.

    • Develop strategies for relaxation: If heart concerns spur anxiety, they can keep your mind racing when you just want to ease into sleep. Techniques like deep breathing, yoga, light stretching, and mindfulness meditation are just a few beneficial approaches for people struggling with how to sleep with pericarditis , heart disease, or other heart problems that cause chest pain.
    • Plan a consistent sleep schedule: Keeping the same bedtime and wake-up time every day is widely considered to be one of the key ways to encourage healthy and stable sleep from night to night.
    • Design an accommodating bedroom: Set your sleep environment to meet your needs by ensuring that the bedroom has a comfortable mattress and pillow, a pleasant temperature, and as much quiet and darkness as possible.
    • Avoid negative influences on sleep: Alcohol and caffeine can both interfere with sleep and are best avoided at night. Excessive use of electronic devices, including your cell phone, can also throw off your sleep patterns, which is why experts recommend not using these devices for an hour or more before bed.

    These tips and other elements of sleep hygiene can serve as a foundation for better sleep, creating habits that make it easier to get both the quantity and quality of sleep that you need.
