Save a Heart, Identify Symptoms of Sleep Apnea

April 3rd, 2009 by Jerusha Michael

This week the CleveMed Sleep Disorders Division traveled to Orlando, FL to attend the American Cardiologist Convention. If you wondered what brings a sleep division to a cardiology conference, this article presents educational tools just for you.

Sleep apnea is a serious chronic disorder affecting more than 15 million Americans. Patients with sleep apnea stop breathing numerous times during the night, which fragments their sleep and stresses the cardiopulmonary system during what is supposed to be a restful and regenerative period. The result is worsening of many heart and lung diseases that often coexist with sleep apnea. Sleep apnea has many forms, like Obstructive (OSA), Central (CSA), and Complex (CompSA). OSA is the only form with an effective treatment - forcing air into the patient’s upper airways via a mask to keep the pharynx open (Continuous Positive Airway Pressure – CPAP). Central or Complex apnea events often coexist with OSA. CSA and CompSA, are strongly linked to serious heart and lung diseases.

Here are just a few interesting numbers:

  • 71% of all patients diagnosed with cardiovascular disease have sleep apnea3
  • OSA patients have diminished heart rate variability and increased BP variability1
  • Treatment of coexisting OSA by CPAP can eliminate recurrent hypoxia and reduce nocturnal BP and heart rate1
  • OSA treated by CPAP resulted in a 58% reduction in the frequency of ventricular premature complexes during sleep1

    Agree and I led this area with Respironics (sleep as it relates to CVD) but to date there isn’t good clinical research studies (randomized, blinded, with a large sample size) showing results in treating sleep apnea and improvement in patients cardiovascular outcomes, e.g., improvement in ejection fractions or leveling thereof, CAD improvements, arythmia improvements. About the only thing you can find is improvement in refractory hypertension which is thought to potentially improve things like stroke, AMI’s, etc but no good data actually showing this. Good luck! The only way in my opinion that sleep apnea (Obstructive and Neuro) will make a significant acceptance amongst cardiology referrals for sleep studies or home studies leading to therapeutic modalities is by having a good outcome based study on therapeutic treatment that leads to a PMA approval. We were on track to do this at Respironics until the CEO pulled the plug on it (had trial in place w sites, etc) because of study costs and time to complete. Good luck! I’m a believer!

    Michael,
    First of all, thanks for commenting :) Your time is greatly appreciated!
    CleveMed is actually currently involved in some clinical studies with Cleveland Clinic and John Hopkins Hospital: http://www.clevemed.com/clevemed_newsreleases/2007_presurgical_inpatient_NIH_grant.shtml

    This is interesting since its focused on the hemodynamics of the heart muscle affected through the primary sleep disorder. Many patients require a multi-disciplined approach to either situation since the cardio-pulmonary systems are so interdependent. The American Association of Respiratory Care has many journal articles concerning treatment of CHF with CPAP and BiLevel Ventilation (non-invasive). Hypoxia due to peripheral vascular disease, artherosclerosis, sleep disordered breathing requires testing, xrays and blood work to determine the primary pathology involved. Home testing through a cardiologists consult for sleep disordered breathing would generally be screened first and foremost with an overnight pulse oximetry trend. Desaturations and documentation of the AHI and events pertaining to arrhythmias would only confirm severity upon the cardiac muscle and provide the necessary data to consult the Pulmonologist or Sleep Specialist.

    This stuff is so important, I remember having dreams of dieing because I was snoring and breathing insufficiently until I had some laser surgery that got rid of that problem. I only have a little problem with stress and not sleeping right because of that. I was out blogging yesterday and came across this awesome sleep better site:

    I feel so much better, thank you!
