What Researchers Did
Researchers randomised 129 patients with acute myocardial infarction into two groups, with one group receiving hyperbaric oxygenation in addition to conventional treatment and the other receiving conventional treatment alone, to assess long-term outcomes.
What They Found
The intervention group, receiving hyperbaric oxygenation, experienced a significantly lower rate of reinfarctions (5.3%) compared to the control group (19%) over two years (p < 0.05). Additionally, survival rates were higher in the intervention group (94.7%) compared to the control group (86.2%) over two years, with a maximal effect of 100% survival in the intervention group versus 91.4% in the control group during the first six months (p=0.05).
Canadian Relevance
This study has no direct Canadian connection as it was conducted in a different country and did not involve Canadian researchers or patients.
Study Limitations
A limitation of this study is its relatively small sample size of 129 patients, which may limit the generalizability of the findings.
