New stroke therapies are needed. This study seeks to provide the preliminary data needed to plan a future study that will evaluate the efficacy of using continuous positive airway pressure (CPAP) to treat stroke patients who have sleep apnea. Our goal is to use this therapy to reduce stroke symptom severity.

Enrollment: 55
Study Start Date: November 2004
Study Completion Date: March 2008
Primary Completion Date: March 2008 (Final data collection date for primary outcome measure)
Intervention Details:
    Procedure: continuous positive airway pressure
    Continuous Positive Airway Pressure initiated within 48 hours of stroke onset and continued for 90 days.
Detailed Description:

BACKGROUND Sleep apnea occurs in 60-96% of stroke survivors and is associated with poor functional recovery and higher post-stroke mortality. Among patients without stroke, continuous positive airway pressure (CPAP) is a safe and effective treatment for sleep apnea. This feasibility pilot study is a step in planning a future efficacy trial of CPAP for patients with acute ischemic stroke.

OBJECTIVES The primary objectives are, among acute ischemic stroke patients, to: (1) determine the feasibility of performing polysomnography; (2) refine the process for providing CPAP within 48-hours of stroke onset; and (3) determine the effect of CPAP on blood pressure.

METHODS This randomized controlled feasibility study will enroll 100 acute ischemic stroke patients. Intervention patients (N=60) receive CPAP within 48 hours of stroke onset and continuing for up to 30 days. At 30 days post-enrollment, the intervention patients undergo unattended polysomnography. Control (N=40) patients receive unattended polysomnography at baseline and after 30 days.

SIGNIFICANCE CPAP represents an important new potential therapy for acute stroke. CPAP may reduce both the neurological symptom severity of the acute stroke and prevent stroke recurrence.
