Cardiovascular disease is the number one cause of death in the US, killing nearly 900,000 people each year. Hypertension, commonly referred to as high blood pressure, is directly related to sleep apnea. The most recent studies prove that people who allow moderate to severe sleep apnea to continue untreated are 7 times more likely to die of cardiovascular complications such as heart attack. Treating a sleep disorder is an important part of heart health.
