Sleep Apnea and Heart Disease, Stroke

Elderly man lost in thought

Plain old snoring can get a little annoying, especially for someone listening to it. But when a snorer repeatedly stops breathing for brief moments, it can lead to cardiovascular problems and potentially be life-threatening.

It’s a condition known as sleep apnea, in which the person may experience pauses in breathing five to 30 times per hour or more during sleep. These episodes wake the sleeper as he or she gasps for air. It prevents restful sleep and is associated with high blood pressure, arrhythmia, stroke and heart failure.

Heart disease is the leading cause of death in the United States, and stroke is also a leading cause of death and disability. High blood pressure is a major risk factor for both.

“The evidence is very strong for the relationship between sleep apnea and hypertension and cardiovascular disease generally, so people really need to know that,” said Donna Arnett, Ph.D., chair and professor of epidemiology at the School of Public Health at the University of Alabama at Birmingham and the incoming president of the American Heart Association.

A Common Problem
According to Dr. Arnett, one in five adults suffers from at least mild sleep apnea, and it afflicts more men than women. The most common type is obstructive sleep apnea (OSA), when weight on the upper chest and neck contributes to blocking the flow of air. OSA is associated with obesity, which is also a major risk factor for heart disease and stroke. Besides obesity contributing to sleep apnea, sleep deprivation caused by sleep apnea can, in an ongoing unhealthy cycle, lead to further obesity. In OSA the upper airway closes off because the muscles that hold it open lose tone. The more weight, the more loss of tone and the more severe the sleep apnea. Each time the airway closes, there is a pause in breathing.

A less prevalent type of sleep apnea is called central sleep apnea (CSA). In CSA the brain doesn’t send regular signals to the diaphragm to contract and expand. There is limited snoring and it has been associated with brain stem stroke because the brain stem is where the impulse to breathe comes from.

Listen to Those Snoring Complaints
A roommate or sleeping partner of someone with sleep apnea often notices it. “It’s really hard to detect if you live alone, unless you go through a sleep study,” Dr. Arnett said. People with sleep apnea may be more tired during the day and therefore prone to accidents or falling asleep.

Getting Proper Treatment
Through treatment known as continuous positive airway pressure, or CPAP, blood pressure is stabilized. The CPAP device involves wearing a mask while sleeping. It keeps air pressure in the breathing passages so they don’t close down.

In a sleep study, doctors count pauses in breathing to determine whether the patient has mild sleep apnea, characterized by five to 15 episodes per hour; moderate sleep apnea, defined by 15 to 30 per hour; or severe sleep apnea, meaning more than 30 each hour.

It’s certainly possible to have simple, loud snoring without sleep apnea. But with regular snoring, the person continues to inhale and exhale. With sleep apnea, the sleeping person tends to have periods when he or she stops breathing and nothing can be heard. The good news is treatment that keeps the breathing passages open and oxygen flowing can yield fast results, Dr. Arnett said. “Blood pressure comes down really quite quickly.”

Getting Good Rest
If you’re struggling to get a good night’s sleep follow some of these suggestions:

  • Get regular physical activity, but don’t do it right before bed because that gets your adrenaline pumping and can keep you awake.
  • Limit alcohol consumption to one drink per day for women and two drinks for men; too much alcohol interferes with sleep.
  • Avoid caffeine before bed.
  • Develop a pre-bedtime routine such as taking a warm bath, dimming the lights or having some herbal tea.

If you are experiencing symptoms of sleep apnea, be sure to discuss this with your primary care provider. A referral to a pulmonologist may be necessary. At Medical Associates, Dr. Mark K. Janes is Board Certified in sleep medicine and provides diagnosis and treatment of sleep disorders including sleep apnea. Examination of abnormalities of sleep is available with overnight trend oximetry and polysomnography.

Three Reasons You Should Quit Smoking NOW!


There are an estimated 40 million adults in the United States who regularly smoke cigarettes—putting them at risk for cancer, stroke, heart disease, lung disease, diabetes and more. At Medical Associates, we believe it’s time to kick smoking in the butt!

After quitting, you can live your life to the fullest as a healthier you.

Did you know that in just a few hours after quitting smoking, your blood pressure levels will immediately begin to drop down to normal levels? Along with your blood pressure, your overall risk of disease will also begin to lower immediately. Your lungs will begin the recovery process, and your skin cells start repairing and rejuvenating themselves. In just a few short weeks, you’ll be able to exercise without becoming winded and your senses of smell and taste will return.

Make a healthier home for yourself and your family.

Separating smokers, opening windows, and using air filters will not prevent your family from breathing in secondhand smoke. Secondhand smoke causes ear infections, more frequent and severe asthma attacks, and more respiratory infections in your children.

Besides the major benefit of protecting your children from the harmful effects of secondhand smoke, you will have more money in your wallet for all of those fun family activities! Use the money you would have spent on cigarettes and create lasting memories with your kids! Quitting is hard, and you should reward yourself and your family for your accomplishments.

It’s never too late to quit.

No matter how old you are, there are several health benefits in store for you when you kick the smoking habit. The number one leading cause of death in the United States is coronary artery disease caused by the effects of smoking. In fact, your risk of developing heart disease is 70% higher if you are a smoker. By quitting, you can save yourself, and your family, from the pain of dealing with a devastating diagnosis. In fact, just one year after quitting smoking, you will reduce your risk of heart disease by half.


Smoking is the leading cause of preventable death in the United States, and is estimated to have caused approximately 440,000 premature deaths in the United States annually. Take charge of your health today, and commit to quit smoking with the help of Medical Associates. If you are a smoker and are ready to quit, contact your health care provider or Kim Ehlers in the Internal Medicine Department to help you develop an individualized quit plan.
