Sleep Lab & Heart Disease

Sleep studies are designed to help diagnose and treat all patients with a wide variety of sleep-related disorders. The National Sleep Foundation estimates that 40 million Americans suffer from some form of a sleep disorder. There are over 80 diagnostic categories of sleep disorders in medical literature and the list is expanding.

Sleep Disorders:

  • Obstructive sleep apnea
  • Periodic limb movements in sleep
  • Insomnia
  • Narcolepsy

Comprehensive Testing

Together, UnityPoint Health - Des Moines and The Iowa Clinic's West Lakes Sleep Center provide a comprehensive variety of tests. They are all digitally recorded, including video monitoring. The initial test - polysomongraphy - is a non-invasive monitoring (no devices need to be inserted inside the body) of a patient's sleep. The test records brainwave activity, eye movements, cardiac activity, oxygen levels and oral/nasal airflow.

Other tests or services include:

  • CPAP/bi-level PAP titration - Continuous Positive Airway Pressure (CPAP) is used to set the right air pressure for CPAP therapy in patients with sleep apnea.
  • Bi-level Positive Airway Pressure - delivers a positive pressure flow, but it changes between inhaling and exhaling. It is most commonly used for patients with obesity-hypoventilation syndrome, COPD, CHF and patients with neuromuscular disease.
  • Multiple Sleep Latency Test (MSLT) for the evaluation of patients with suspected narcolepsy and daytime sleepiness.
  • Maintenance of Wakefulness Test (MWT) is indicated in the evaluation of whether patients can stay awake under low light and monotonous conditions.

The Connection Between Heart Disease and Sleep Apnea

Sleeping five hours or less each night significantly raises the risk of developing high blood pressure in adults. Getting enough sleep is important to your health, and might be helpful in warding off high blood pressure, which can lead to a number of other problems, including heart and kidney disease and stroke.
