The Link between Sleep Apnea and Heart Health

Research has shown that people with sleep apnea are at an increased risk of developing cardiovascular disease. This is because sleep apnea can lead to several changes in the body that can negatively impact heart health. Some of how sleep apnea can affect heart health include:


Sleep apnea can cause repeated drops in blood oxygen levels, leading to increased blood pressure. Over time, this can lead to hypertension, a risk factor for heart disease.


Sleep apnea can also cause changes in how the heart beats, leading to arrhythmias. These irregular heartbeats can increase the risk of stroke, heart failure, and other cardiovascular problems.

Heart Failure

People with sleep apnea are at an increased risk of developing heart failure, a condition in which the heart can’t pump enough blood to meet the body's needs. This can lead to fatigue, shortness of breath, and other symptoms.

Coronary Artery Disease

Sleep apnea has also been linked to an increased risk of developing coronary artery disease, in which the arteries that supply blood to the heart become narrow or blocked. This can lead to chest pain, heart attacks, and other serious complications.

Heart Benefits of Treating Sleep Apnea

Treating sleep apnea can have significant heart benefits. Here are some ways treating sleep apnea can improve heart health:

  • Reduced High Blood Pressure: Sleep apnea is often associated with high blood pressure, and treating sleep apnea can lower blood pressure levels. By reducing blood pressure, the risk of heart disease and stroke can also be reduced.
  • Lowered Risk of Heart Disease: Studies have shown that people with untreated sleep apnea are at a higher risk of heart disease. By treating sleep apnea, the risk of developing heart disease can be reduced.
  • Improved Heart Rhythm: Sleep apnea can disrupt the normal heart rhythm, which can increase the risk of heart arrhythmias. By treating sleep apnea, the risk of heart arrhythmias can be reduced.
  • Reduced Risk of Heart Failure: Sleep apnea can put extra strain on the heart, which can lead to heart failure. By treating sleep apnea, the risk of heart failure can be reduced.

Diagnosis and Treatment of Sleep Apnea

The first step in diagnosing sleep apnea is to undergo a sleep study, also known as a polysomnography. This study involves monitoring your breathing, heart rate, and other bodily functions while you sleep. The results can help determine the severity of your sleep apnea and guide treatment options.

It’s crucial to work with your McKinney sleep specialist to determine the best treatment plan for your individual needs. With proper diagnosis and treatment, sleep apnea can be effectively managed to reduce the risk of heart disease and other health problems.

Frequently Asked Questions

Can sleep apnea cause a heart attack?

Yes, sleep apnea has been linked to an increased risk of heart attacks. People with sleep apnea are more likely to have high blood pressure, which can strain the heart and increase the risk of heart attacks.

Can heart damage from sleep apnea be reversed?

Heart damage caused by sleep apnea can often be reversed with treatment. This may include using a CPAP machine to improve breathing while sleeping and making lifestyle changes such as losing weight, quitting smoking, and exercising regularly.

Is a CPAP machine good for your heart?

Yes, using a CPAP machine to treat sleep apnea can benefit your heart health. CPAP therapy helps to keep the airway open while you sleep, reducing the risk of breathing interruptions. This can help to lower blood pressure and reduce the risk of heart disease.

Can a cardiologist tell if you have sleep apnea?

While cardiologists are not sleep specialists, they may be able to recognize the signs of sleep apnea and refer you to a sleep specialist for diagnosis and treatment. Cardiologists may be particularly attentive to patients with sleep apnea symptoms if they have other risk factors for heart disease, such as high blood pressure or a family history of heart disease.
