Type-2 Diabetes and Sleep Apnea Syndrome (SAS) are both related to an increase in platelet activation. Type 2 diabetes is often associated with sleep apnea syndrome with a prevalence up to 60%.
The main objective of our study is to analyze the influence of sleep apnea on the response to antiplatelet therapy in stable aspirin-treated type-2 diabetes patients.
Consecutive stable aspirin-treated type-2 diabetes patients referred for suspicion of sleep apnea will be recruited after providing informed consent. Response to aspirin will be assessed with the Verify Now Aspirin(TM)rapid analyser in the morning after nocturnal polysomnography, and compared with a group of type-2 diabetes free of sleep apnea. Other endocrine, metabolic, hematologic and cardiovascular confounders will also be assessed at baseline to determine their influence on the response to aspirin.
Then, Patients with severe SAS (Apnea-Hypopnea Index> 30 events/h) and response with Aspirin (ARU > 454) will be randomized to 3 months of active or sham continuous positive airway pressure treatment in a pilot study. After the 3-months of intervention, response to aspirin will be compared between the sham and effective CPAP groups.

Active Comparator: CPAP
This device consists in a nasal continuous positive airway pressure (CPAP). It will be applied 3 months after the beginning of drug treatment and for 3 months.
Other Name: positive airway pressure
Placebo Comparator: Sham-CPAP
This device consists in a sham CPAP. It will be applied 3 months after the beginning of drug treatment and for 3 months.
- Response to antiplatelet therapy [ Time Frame: Measure will be done in the morning after the sleep diagnosis ]
- Effects of CPAP treatment for severe obstructive sleep apnea on aspirin efficacity in type-2 diabetic patients [ Time Frame: Change from baseline after 3 months randomized treatment ]
