To the Editor,
Molecular hydrogen (H2) has been recently introduced as an experimental medical gas in clinical medicine . Beneficial effects of H2 are attributed to its antioxidant, anti-apoptotic and anti-inflammatory properties, with H2 administered via oral, parenteral or inhalational route found beneficial in cardiometabolic disorders . However, no information is currently available concerning its efficacy and safety to affect cardiometabolic risk factors in elderly. This population faces the highest risk for cardiometabolic morbidity , and any intervention that would help improve cardiometabolic profiles is highly required.
In this pilot study, we evaluated the impact of short-term H2 inhalation on the American Heart Association (AHA) cardiovascular risk scores, health-related physical fitness, and cardiometabolic biomarkers in men and women aged 65 years or older. Sixteen (n = 16) community-dwelling aged adults (14 women and 2 men; age 68.1 ± 5.3 years; BMI...
