What Researchers Did
Researchers evaluated the effect of hyperbaric oxygenation therapy on echocardiographic parameters in 31 asymptomatic patients undergoing treatment for cognitive impairment.
What They Found
They found that after 60 sessions of hyperbaric oxygenation therapy, ejection fraction increased from 60.71% to 62.29% (p=0.02), and left ventricular end systolic volume decreased from 38.08 ml to 35.39 ml (p=0.01). Myocardial performance index also improved from 0.29 to 0.26 (p=0.03), and global longitudinal strain increased from -19.31% to -20.16% (p=0.036).
Canadian Relevance
This study has no direct Canadian connection as it was not conducted in Canada, nor did it involve Canadian participants or researchers.
Study Limitations
A limitation of this study is its small sample size of 31 patients and the specific patient population undergoing treatment for cognitive impairment, which may limit generalizability.
