IV Hydrogen Nanobubbles for Cardiac Function and QoL

"This study investigated a novel intervention using intravenous hydrogen nanobubbles (HNBs), which are microscopic hydrogen gas bubbles encapsulated in liquid, offering enhanced stability, deep tissue penetration, and sustained antioxidant and anti-inflammatory effects. Unlike other hydrogen therapies (such as inhalation or hydrogen-rich water), this method delivers HNBs directly into the bloodstream.~Participants were randomized into six groups: one control group receiving saline and five intervention groups receiving escalating doses of HNBs (5-25 mL) over 10 intravenous infusions in 5 weeks. This intervention is distinct for its dose-response design, intravenous delivery, and combined evaluation of cardiovascular function and quality of life (SF-36)-a patient-centered approach not commonly found in similar studies."
