TL;DR
Hydrogen treatment, whether taken orally or by injection, can help reduce the severity of lung-related high blood pressure in rats.
Key Finding
In rats with chemically-induced pulmonary hypertension, oral hydrogen water reduced lung inflammation and prevented right heart enlargement with effectiveness similar to injected hydrogen.
Summary
Researchers gave rats a chemical that causes lung high blood pressure, then treated some with hydrogen-enriched water to drink and others with injected hydrogen. Both treatments reduced markers of lung damage and inflammation, and prevented the heart from thickening abnormally. Oral hydrogen water worked about as well as injected hydrogen but would be easier for patients to use.
Practical Takeaway
This rat study suggests hydrogen water may help protect against lung high blood pressure through antioxidant effects, but human studies are needed to determine if these results apply to people. The study does not establish that hydrogen water can treat or prevent pulmonary hypertension in humans.
Abstract
This study aimed to explore the protective effect of hydrogen as an antioxidant on monocrotaline (MCT)-induced pulmonary hypertension (PH). Forty-eight SD rats were equally randomized into four groups: SHAM group, MCT group, MCT+Oral-H2 group and MCT+Inj-H2 group. The results showed that the mean pulmonary arterial pressure, right ventricle weight and right ventricular hypertrophy index in MCT group were significant higher than those in SHAM group; pulmonary inflammatory response, atrial natriuretic factor, 3-nitrityrosine and intercellular adhesion molecule-1 were also increased significantly in MCT group. These indexes were decreased significantly in both MCT+Oral-H2 group and MCT+Inj-H2 group, which indicate Oral-H2 and Inj-H2 have similar effects of preventing the development of PH and mitigating RV hypertrophy. The protective effect of hydrogen is associated with its antioxidative ability and action of reducing pulmonary inflammatory response. While Oral-H2 is more convenient than Inj-H2, Oral-H2 may be ideal for clinical use in future.
