Sleep Apnea and Your Heart: The Hidden Link You Can’t Ignore

Many of us snore at night, but sometimes, this minor annoyance is actually a sign of obstructive sleep apnea (OSA). This is a serious medical condition where the airway collapses during sleep, cutting off breathing. While the immediate side effects, like daytime fatigue, morning headaches, and irritability, are well known, the long-term damage OSA inflicts on the cardiovascular system is far more dangerous. With this in mind, let’s take a closer look at sleep apnea, how it affects your heart, and the ways Cardiac Associates of North Jersey in Oakland and Fairfield, NJ can help.

How Sleep Apnea Damages the Heart

Why does a respiratory problem cause heart problems? To understand this question, we have to look at what happens during sleep apnea. When a patient with OSA falls asleep, the soft tissue in the throat collapses, blocking the airway. The body continues trying to breathe against this blockage, but oxygen levels in the blood plummet. This triggers several negative reactions, driven by the following:

• Drops in Oxygen Levels—When you stop breathing, your oxygen saturation falls, but when you gasp and wake up, it rises again. This cycle can happen dozens of times per hour. These rapid fluctuations cause stress and inflammation throughout the body, damaging the lining of the blood vessels and stiffening the arteries.
• Autonomic Surges—When your brain realizes you aren’t breathing, it triggers a “fight or flight” response to wake you up just enough to open your airway. This releases a surge of stress hormones, including adrenaline and cortisol. Even though you are asleep, your heart rate spikes and your blood pressure shoot up. This places additional stress on the heart when it’s supposed to be resting.

The Cardiovascular Risks of Untreated OSA

Given the ways it can damage the heart, sleep apnea and cardiology go hand-in-hand. Get to know a few conditions that can arise in part due to untreated sleep apnea:

Resistant Hypertension

High blood pressure is the most common cardiovascular condition associated with sleep apnea. Many patients with hypertension also have sleep apnea, and some even have resistant hypertension. This type of high blood pressure remains uncontrolled despite taking three or more medications. For these patients, treating the underlying sleep apnea is crucial, as it can help finally stabilize their blood pressure.

Atrial Fibrillation (AFib)

AFib and sleep apnea are also related. Those with severe sleep apnea may be more likely to develop arrhythmias. The changes in chest pressure during struggling breaths, combined with the structural changes to the heart caused by hypertension, create an environment ripe for irregular heartbeats. Furthermore, if you are being treated for AFib but fail to treat the underlying apnea, it’s more likely that the arrhythmia will return later.

Heart Failure and Stroke

The relentless stress on the heart muscle can eventually make the heart too weak or stiff to pump blood properly, ultimately leading to heart failure. Additionally, the inflammation and high blood pressure caused by OSA increase the risk of stroke. The sudden drops in oxygen levels can reduce blood flow to the brain, while the increased pressure damages the delicate cerebral blood vessels.

How to Get Screened for OSA

Too often, people don’t realize that OSA and heart disease are related. Because of this, they never get screened, and their condition goes undiagnosed for too long. If you’re struggling with sleep apnea, reach out to a cardiologist in Oakland or Fairfield, NJ. They sometimes use the STOP-BANG questionnaire to determine your risk level. If you answer “yes” to three or more of the following questions, you may be at high risk for OSA:

• Snoring: Do you snore loudly?
• Tired: Do you feel tired or sleepy during the daytime?
• Observed: Has anyone observed you stop breathing during sleep?
• Pressure: Do you have high blood pressure?
• BMI: Is your Body Mass Index higher than 35?
• Age: Are you older than 50?
• Neck size: Is your neck circumference large (greater than 17 inches for men, 16 for women)?
• Gender: Are you male?

Sleep Apnea Treatments That Could Work for You

If you’re diagnosed with both a heart condition like hypertension and sleep apnea, seeking prompt treatment from Cardiac Associates of North Jersey is your best course of action. Typically, the goal is to keep the airway open while you sleep to prevent oxygen drops and adrenaline spikes. Here are some commonly recommended treatments:

• CPAP Therapy—Continuous Positive Airway Pressure (CPAP) is one of the top treatments. A machine delivers a gentle stream of air through a mask and keeps the throat open. Consistent CPAP use has been shown to lower blood pressure and reduce the recurrence of AFib.
• Oral Appliances—For patients with mild to moderate apnea, a custom-fitted oral appliance is a highly effective alternative to CPAP. These devices look like sports mouthguards and work by repositioning the lower jaw slightly forward to prevent the airway from collapsing.
• Lifestyle Changes—Weight loss, sleeping on your side, and avoiding alcohol before bed are helpful lifestyle changes that can supplement other treatments. Keep in mind that these may not be enough to cure moderate-to-severe sleep apnea on their own.
