BOSTON—A portable cardiopulmonary screening method could be a reliable tool for the early diagnosis of sleep apnea in patients with acute ischemic stroke, according to research presented at the 26th Annual Meeting of the Associated Professional Sleep Societies.
The technique provided similar diagnostic information to that of polysomnography, said Oleg Chernyshev, MD, Assistant Professor of Neurology at the University of Texas in Houston, and Clinical Assistant Professor of Neurology at the Louisiana State University Health Sciences Center, Shreveport, LA.
Dr. Chernyshev and his colleagues performed simultaneous bedside level-three cardiopulmonary and polysomnography studies of 21 patients with acute ischemic stroke. All patients were observed within 72 hours of stroke onset. The researchers compared the accuracy of cardiopulmonary testing with that of polysomnography using various statistical analyses.
Fifty-eight percent of the study population was African American, and 52% were male. The population’s mean age was 61, mean neck circumference was 16.8 inches, and mean BMI was 30. On admission, patients had a mean NIH Stroke Scale score of 6 and a mean modified Rankin Scale score of 3.
