Title: Usefulness of a Telemedicine System for OSA Patients Follow-up With High Cardiovascular Risk
Brief Summary: The aim of this study is to determine the usefulness of a telemedicine system for the follow-up of OSA patients with a high cardiovascular risk. Our hypothesis is that the telemedicine system will enhance compliance and thus reduce self-measured blood pressure.


Options:
A: Inclusion Criteria:

* 18 to 85 years old men and women
* stable patient
* BMI\<40kg/m²
* OSA patients diagnosed with polysomnography or polygraphy
* SCORE\>5% and/or cardiovascular disease pas history :
* transient ischemic attack, stroke, cerebral haemorrhagy
* myocardial infraction, angor, coronary revascularization, arteriopathy, aortic aneurism

Exclusion Criteria:

* central sleep apnea syndrome
* SCORE\<5%
* cardiac failure
* past history of hypercapnic chronic respiratory failure
* past history of severe or intercurrent pathology which can not allow the patient follow-up
* Incapacitated patients in accordance with article L 1121-6 of the public health code
* patients taking part in another clinical trial
B: Inclusion Criteria:

Individuals willing to participate must meet the following eligibility criteria prior to enrollment:

* Patients referred for a sleep evaluation for suspected sleep apnea.
* Age 18 years or older
* Living within 90 miles of the Sleep Center.

Exclusion Criteria:

Individuals will be excluded from the study for the following reasons:

* Unable or unwilling to provide informed written consent.
* Lack of telephone access or inability to return for follow-up testing.
* A history of prior sleep evaluations, OSA treatment, or sleep disorder in addition to OSA.
* A clinically unstable chronic medical condition as defined by a new diagnosis or change in medical management in the previous 3 months of cardiac disease, thyroid disease, diabetes, depression or psychosis, cirrhosis, or recently diagnosed cancer.
* Individuals already on long term oxygen therapy or requiring bilevel positive airway pressure.
* Individuals with rotating shift work or irregular work schedules over the last 6 months.
* Suspected or confirmed to be pregnant. A pregnancy test will be performed using the urine sample obtained at the initial visit.
* Inability to complete the Assessment Battery - e.g. less than a 5th grade reading level
C: Inclusion Criteria:

* Physician diagnosis of obstructive sleep apnea syndrome plus polysomnography demonstrating greater than 10 apneas plus hypopneas per hour of sleep
* Age 18-80 years
* Ability to use a telephone without assistance

Exclusion Criteria:

N/A
D: Inclusion Criteria:

* referred to the FMC Sleep Centre for assessment of SDB
* meet one of the three criteria for suspected severe SDB:

  1. Respiratory disturbance index (RDI) \>/= 30 events/hour on an ambulatory sleep test
  2. Mean nocturnal oxygen saturation \</= 85% on an ambulatory sleep test
  3. Suspected hypoventilation, defined by an RDI \>/= 15 events/hour on an ambulatory sleep test and partial pressure of carbon dioxide \>/= 45 mmHg on arterial blood gas
  4. On supplemental oxygen therapy with high suspicion of SDB (as determined by physician review of referral)

Exclusion Criteria:

* Suspected concomitant sleep disorder other than SDB
* A previous diagnosis of OSA treated with PAP or dental appliance
* Primary health insurance provided by a province other than Alberta
* Failure to provide consent to participate in the study
* Under the age of 18
