The Sleep and Heart Connection

Sleep. It is as vital as breathing. In fact, without proper restorative sleep even breathing becomes a problem! Individuals who suffer from a sleep disorder such as sleep apnea experience numerous pauses in their breathing rhythm throughout the course of the night and often wake up gasping for air. Without treatment, this lack of restorative sleep can eventually lead to cardiovascular disease. High blood pressure, arrhythmia, stroke and even heart healthheart failure are all associated with sleep apnea.

Heart disease is the leading cause of death in the United States, and stroke is not far behind at number five so it is not something to take lightly. If you suspect you or a loved one might have sleep apnea, it is essential to talk to your doctor right away and be set up for a sleep study. The longer you put off treatment, the more potential damage you could be doing to your heart. In a normal sleep cycle, the heart gets an opportunity to rest; blood pressure goes down as well as heart rate. Without this break, the heart rate stays elevated which then induces high blood pressure which leads to cardiovascular disease.

The European Heart Journal conducted a study of 475,000 individuals and discovered that those who slept less than six hours a night had a 48% greater risk of developing or dying from coronary heart disease and a 15% increased risk of having or dying from a stroke. An individual who suffers from a sleep disorder sometimes never enters into restorative sleep even if they think they are sleeping, and that just plays havoc on the heart as well as other parts of the body.

The good news is that there is treatment available for sleep apnea sufferers. If a sleep study or polysomnogram (PSG) identifies a patient as having sleep apnea, they will most likely be fitted with a CPAP (continuous positive airway pressure) machine. A CPAP machine increases air pressure in the throat so that the airway does not become blocked during sleep; this allows the lungs to breathe properly and lets the body go into restorative sleep.

Patients who have heart arrhythmias or high blood pressure caused by sleep apnea, can oftentimes resolve the conditions by the use of a CPAP machine. Evidence has shown that proper treatment not only lowers blood pressure during the night, but it also lowers it during the day as well. Arrhythmias or irregular heartbeats are also decreased with proper treatment; sixty percent of patients never have to return for treatment of their arrhythmias after starting on a CPAP machine. Good sleep is vital, so don’t ignore it if you are not getting enough rest at night, talk to your physician and take the first step on the path to a healthier you.
