H2HUBB TAKEAWAY
In rats, 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. These preclinical findings add evidence supporting molecular hydrogen's therapeutic potential within the outcomes and biological pathways measured in this model.

What the Researchers Studied
The researchers studied rats. The study used a preclinical animal experiment.
What Effects Did Molecular Hydrogen Have?
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. 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.
