What Researchers Did
Researchers retrospectively analyzed 98 patients with slow coronary flow, comparing those who received hyperbaric oxygen therapy plus conventional treatment (n=48) with a control group receiving conventional treatment alone (n=50) over 4 weeks.
What They Found
Before treatment, there were no significant differences in vascular endothelial function markers between the two groups (p > 0.05). After 4 weeks, the hyperbaric oxygen group showed significantly increased flow-mediated vasodilation (FMD) and plasma levels of nitric oxide (NO) and calcitonin gene-related peptide (CGRP) compared to the control group.
Canadian Relevance
This study was conducted in China and has no direct Canadian connection.
Study Limitations
As a retrospective study with a relatively small sample size of 98 patients, the findings may not be broadly generalizable.
