TL;DR
Drinking hydrogen-rich water may help reduce heart damage after a heart attack by activating a protective signaling pathway in the body.
Key Finding
Hydrogen-rich water activated a protective cellular signaling pathway (PI3K/AKT) and significantly reduced cell death markers in rat hearts experiencing ischemia-reperfusion injury.
Summary
Researchers studied whether hydrogen-rich water could protect rat hearts from damage caused by temporarily blocking and then restoring blood flow (a condition called ischemia-reperfusion injury). They perfused isolated rat hearts with either regular solution or solution containing hydrogen-rich water, then subjected them to a period of blocked blood flow followed by restored blood flow. The hydrogen-rich water activated a protective cellular pathway (PI3K/AKT) and reduced markers of cell death in heart tissue compared to the control group.
Practical Takeaway
This is an early-stage animal study using isolated rat hearts in a laboratory setting, so results cannot yet be applied to humans. While the findings suggest hydrogen-rich water may have potential cardioprotective effects, human clinical trials would be needed to determine if these benefits translate to people experiencing heart-related conditions.
Abstract (excerpt)
Background: The effects of hydrogen-rich water on PI3K/AKT-mediated apoptosis were studied in rats subjected to myocardial ischemia-reperfusion injury (MIRI). Methdos: Sixty rats were divided randomly into a hydrogen-rich water group and a control group. The hearts were removed and fixed…
