What Researchers Did
Researchers prospectively enrolled 57 patients with peripheral arterial occlusive disease to investigate if hyperbaric oxygen therapy improved circulating endothelial progenitor cells, angiogenesis factors, and blood flow in ischemic areas.
What They Found
After hyperbaric oxygen therapy, circulating levels of endothelial progenitor cells and soluble angiogenesis factors (SDF-1α, VEGF, HGF) significantly increased (all p < 0.001). Skin perfusion pressure, indicating blood flow in ischemic areas, also significantly improved (p < 0.001), with EPC numbers correlating positively with angiogenesis factors and SPP.
What This Means for Canadian Patients
For Canadian patients with peripheral arterial occlusive disease, these findings suggest that hyperbaric oxygen therapy could potentially enhance the body's natural repair mechanisms. This may lead to improved blood flow and better outcomes in ischemic areas, offering a potential therapeutic option.
Canadian Relevance
This study has no direct Canadian connection.
Study Limitations
A limitation of this prospective study is the lack of a control group, which could impact the generalizability of the findings.
