What Researchers Did
Researchers studied gas exchange values in 94 patients who experienced complicated myocardial infarction, also known as a heart attack.
What They Found
They observed that the degree of tissue hypoxia, or lack of oxygen, correlated with the severity of complications during the acute stage of the heart attack. Adding hyperbaric oxygenation (HBO) in a sparing regimen to combined therapy effectively reduced tissue hypoxia and improved the heart's contractile and pumping function. HBO combined with antioxidants was most effective in early post-heart attack patients with signs of heart enlargement and decreased contractility, especially when oxygen levels were significantly low.
Canadian Relevance
No direct Canadian connection identified.
Study Limitations
This study was a case report (or series) and lacked a control group, making it difficult to definitively prove the effectiveness of hyperbaric oxygenation.
