About this trial

The study aims to evaluate whether early treatment of obstructive sleep apnea with continuous positive airway pressure in ischemic stroke patients has a favorable effect on functional recovery.

Disqualifiers

Prior stroke

Previous diagnosis of OSA with current CPAP use or previously failed CPAP

Pre-stroke disability (mRS > 1)

Coma or stupor

Trial outcomes

Primary outcomes

1

Functional disability

Measured by the modified Rankin Scale, ranging from 0 (no symptoms) to 6 (death), with higher scores indicating greater disability and dependence on daily activities.

Time frame
3 months

Secondary outcomes

1

Neurological impairment

Stroke severity will be measured by National Institutes of Health Stroke Scale, which ranges from 0 to 42, with higher scores reflecting greater neurological impairment. Neurological deterioration was defined as an increase of 4 or more points on the NIH Stroke Scale within 72 hours after stroke onset

Time frame
Admission, 72 hours, day 5/discharge, 3 months, and 6 months
2

Functional independence

Measured by the modified Rankin Scale (dichotomized analysis with mRS ≤ 2) and the Barthel Index, which ranges from 0 (worst, fully dependent) to 100 (best, independent).

Time frame
Day 5/discharge, 3 months, 6 months, 1 year, and 2 years
3

Cognitive impairment

Evaluated through the Montreal Cognitive Assessment, which was developed as a brief screening instrument for mild cognitive impairment. It assesses different cognitive domains, scoring up to 30.

Time frame
Day 5/discharge, 3 months, 1 year, and 2 years
4

Subjective quality of life

Measured by the EuroQol-5 Dimension (no problems = 1; some problems = 2; and extreme problems or unable to = 3).

Time frame
Day 5/discharge, 3 months, 6 months, 1 year, and 2 years
