Attentional Capacity and Working Memory in Coronary Artery Disease Patients: Impact of the Presence of a Sleep Apnea Syndrome and Chronic Effects of Treatment With CPAP (CAPCORSAS)
Attentional Capacity and Working Memory in Coronary Artery Disease Patients: Impact of the Presence of a Sleep Apnea Syndrome and Chronic Effects of Treatment With a Continuous Positive Airway Pressure System (CPAP). Etude CAPCORSAS
The presence of Obstructive Sleep Apnea Syndrome (OSAS) has a high frequency in patients victims of a coronary artery disease (CAD) (myocardial infarction, revascularization). Unlike patients seen in a sleep Laboratory with an impact on daytime functioning, CAD apneic patients do not complain in their daytime functioning. The objective of this study is to explore whether the objective cognitive assessment measures may be a good marker of the efficacy of CPAP treatment given to non-sleepy apneic CAD patients.
Coronary patients with an AHI between 15 and 40 / h will be treated (or not) after randomization with CPAP treatment. The expected results are: CPAP apneic coronary patients should have a positive impact on cognitive performance, particularly on attention span and working memory measured by improvement in the Paced Auditory Serial Addition Test score (PASAT score).

Interventie / Behandeling |
---|---|
Experimenteel: Patients treated
Patients with CAD and SAS.
This patients should have an apnea-hypopnea index (AHI) between 15 and 40, and an Epworth sleepiness score (ESS) <10.
After randomization, they will be treated with CPAP treatment.
|
Patients treated wear a face mask during sleep which is connected to a pump (CPAP machine) that forces air into the nasal passages at pressures high enough to overcome obstructions in the airway and stimulate normal breathing.
|
Geen tussenkomst: Patients non-treated
Patients with CAD and SAS.
This patients should have an apnea-hypopnea index (AHI) between 15 and 40, and an ESS <10.
After randomization, they will be not treated.
|
|
Geen tussenkomst: Control group
Patients with CAD but without SAS (AHI<15).

Maatregel Beschrijving |
Tijdsspanne |
---|---|---|
PASAT-4sec test score
Tijdsspanne: Day 120
|
The PASAT is a measure of cognitive function that assesses auditory information processing speed and flexibility, as well as calculation ability.
Single digits are presented every 4 seconds and the patient must add each new digit to the one immediately prior to it.
The score for the PASAT is the total number correct out of 60 possible answers.
