H2HUBB TAKEAWAY
The myocardial infarct size, no-reflow area, cardiac function, microstructure and mitochondrial morphology of I/R model rats were significantly improved after hydrogen inhalation. These results are preclinical and suggest molecular hydrogen's therapeutic potential in the condition studied. Further human research is needed to establish clinical effectiveness.
What the Researchers Studied
The principle purpose of this study is to validate the effect of hydrogen gas on IHD and further explore the mechanism of hydrogen gas in alleviating myocardial I/R injury and no-reflow phenomenon.
How Molecular Hydrogen Was Used
KEY FINDINGS: The myocardial infarct size, no-reflow area, cardiac function, microstructure and mitochondrial morphology of I/R model rats were significantly improved after hydrogen inhalation. The researchers found that oxidative stress and NLRP3 mediated pyroptosis are the important mechanisms for hydrogen to alleviate myocardial I/R injury, and the researchers also confirmed that hydrogen can significantly improve no reflow phenomenon caused by ischemia-reperfusion.
