Sleep medicine is a relatively new field that has gained increasing recognition for its impact on heart health. As we learn more, we are finding that problems with sleep, including sleep apnea, can have potentially severe effects on the cardiovascular system including possible increased risk of hypertension, arrhythmia, including atrial fibrillation, heart disease and stroke.
Sleep apnea carries additional relevant health risks including type 2 diabetes, metabolic syndrome, complications with medications and surgery, liver problems. Patients may notice subjective complaints such as troubles staying asleep, awakening with a morning headache, dry mouth, unrefreshed with daytime sleepiness, difficulties concentrating, with short term memory, irritability and possibly sleep-deprived partners.

Referral to a sleep specialist who will review the signs, symptoms, and sleep history and determine need for further evaluation. Testing includes:
The most widely accepted treatment is the use of Continuous Positive Airway Pressure (CPAP), delivered through a mask worn when sleeping. The mask provides an “air splint” to keep the breathing passages open throughout all stages of sleep. Modern CPAP units are quiet and portable, and new technologies have produced a variety of the most comfortable and least intrusive masks to date.
For those patients who cannot tolerate CPAP, second line treatments are available, including dental appliances and surgery.
