What Researchers Did
Researchers conducted a pilot randomised controlled trial with 24 STEMI patients to compare SPECT findings at 6 weeks in those receiving hyperbaric oxygen therapy (HBOT) after primary percutaneous coronary intervention (PPCI) versus a control group.
What They Found
At 6 weeks, the HBOT group showed a significant reduction in affected SPECT segments from 47.1% to 33.7% (p=0.039), while the control group's reduction from 55.5% to 45.9% was not statistically significant (p=0.090). Both groups experienced a decrease in summed rest score (HBOT: 20 to 12.7, p=0.0017; control: 23 to 16.7, p=0.031) and improved left ventricular ejection fraction (HBOT: 44% to 57.2%, p=0.011; control: 45.9% to 55%, p not fully reported).
Canadian Relevance
This study was not conducted in Canada and does not have a direct Canadian connection.
Study Limitations
A significant limitation of this study is its small sample size and pilot nature, which restricts the generalizability of the findings.
