Patient selection: acute ischemic stroke
Usual timing: first few days after the stroke
Risk factors for Cheyne-Stokes breathing:
(1) older age (mean age 66 in study population)
(2) ECG abnormalities (sinus bradycardia, sinus tachycardia, ST segment abnormality, T-wave abnormality, AV block)
(3) lower left ventricular ejection fraction (less than 56%)
(4) stroke location (see below)
The risk of CSB is highest for an extensive left-sided hemispheric stroke. The rate was high in patients with stroke in the anterior circulation
The risk of CSB is low if the stroke is limited to (a) the left insular or (b) the mesencephalic region.
