Heart failure (HF) is increasing in prevalence in many countries around the world. HF is a complex clinical syndrome characterized by the heart’s inability to pump blood effectively, resulting in significant morbidity and mortality. After an initial cardiac event (e.g., myocardial infarction, valve dysfunction, hypertension, etc.), adaptive mechanisms are activated to preserve cardiac function. Su

Oxidative stress is responsible for the pathogenesis of many diseases, and antioxidants are commonly included in their treatment protocols. Over the past two decades, numerous biomedical reports have revealed the therapeutic benefits of molecular hydrogen (H2) in relieving oxidation-related diseases. H2 has been found to have selective antioxidant properties against the most dangerous oxidants (hy

Mitochondria originated from aerobic bacteria in endosymbiosis. Through this symbiosis, eukaryotes acquired an efficient energy-producing system, but at the cost of exposure to oxidative stress from reactive oxygen species (ROS). Molecular hydrogen (H2) was recently identified as an antioxidant that selectively reduces ROS, such as hydroxyl radicals and peroxynitrite, which are strong oxidants, and

The aim of the review was to examine the main characteristics of hydrogen ion metabolism and its hemostatic function in the human body. For diagnostic purposes, molecular hydrogen (H2) is considered a biological marker. The results of the analysis of therapeutic programs for the clinical use of hydrogen are presented. The use of H2 as a drug in the treatment of more than 170 diseases is also discu

Obstructive sleep apnea (OSA) is a chronic condition characterized by recurrent upper airway collapse during sleep, leading to chronic intermittent hypoxia (CIH) that can cause oxidative stress and chronic inflammation that lead to cardiovascular disease (CVD). Although continuous positive airway pressure (CPAP) treatment is the gold standard for OSA treatment, it has little or no benefit in reduc

Disproportion between reactive oxygen species (ROS) production and the body's antioxidant system can cause oxidative stress, which is considered a common denominator in various pathological conditions, including cardiovascular diseases, aging, and cognitive disorders. The generation of free radicals, which occurs through partial reduction of oxygen, can quickly overwhelm the endogenous antioxidant

Over the last two decades, a plethora of disease models and human studies have confirmed the beneficial effects of molecular hydrogen (H2), a simple biotherapeutic gas. Recent small-scale studies evaluating the effects of hydrogen-rich water (HRW) on various metabolic conditions pointed to advantageous effects of HRW in regulating blood lipid profiles. However, to the best of the authors’ knowledge,

Hydrogen-rich water (HW) has been suggested to possess antioxidant properties of value in treatments of lifestyle diseases and for prevention of latent pathologies. To date, the potential benefits of HW against the deleterious effects of excessive salt intake and hypertension have not been investigated.

Molecular hydrogen (H2) is a colorless and odorless gas. Studies have shown that H2 inhalation has the therapeutic effects in many animal studies and clinical trials, and its application is recommended in the novel coronavirus pneumonia treatment guidelines in China recently. H2 has a relatively small molecular mass, which helps it quickly spread and penetrate cell membranes to exert a wide range

Oxidative stress and inflammation are closely related to atherosclerotic cardiovascular disease. It is established that hydrogen has significant protective effects on many diseases as a potential antioxidative and anti-inflammatory agent. The purpose of this study is to evaluate the effect of hydrogen on unstable angina in vitro and in vivo. An atherosclerosis model in vitro was constructed by ox-

Background: Mounting evidence indicates that hydrogen gas (H2) is a versatile therapeutic agent, even at very low, non-combustible concentrations. The Chinese National Health and Medical Commission recently recommended the use of inhaled H2 in addition to O2 therapy in the treatment of COVID-19-associated pneumonia, and its effects extend to anti-tumor, anti-inflammatory and antioxidant actions.

Purpose: Metabolic syndrome is associated with several medical risk factors including dyslipidemia, hyperglycemia, and obesity, which has become a worldwide pandemic. The sequelae of this condition increase the risk of cardiovascular and neurological disease and increased mortality. Its pathophysiology is associated with redox dysregulation, excessive inflammation, and perturbation of cellular hom

Background: Measurement of the reactive hyperemia index (RHI) using peripheral arterial tonometry (PAT) has shown benefits in the evaluation of vascular endothelial function and prediction of cardiovascular disease prognosis. Thus, it is important to examine the factors that promote the RHI. In this study, we aimed to investigate the effect of molecular hydrogen (H2) on reactive hyperemia-PAT of t

Excessive production of oxygen free radicals has been regarded as a causative common denominator of many pathological processes in the animal kingdom. Hydroxyl and nitrosyl radicals represent the major cause of the destruction of biomolecules either by a direct reaction or by triggering a chain reaction of free radicals. Scavenging of free radicals may act preventively or therapeutically. A number

Studies on molecular hydrogen have evolved tremendously from its humble beginnings and have continued to change throughout the years. Hydrogen is extremely unique since it has the capability to act at the cellular level. Hydrogen is qualified to cross the blood brain barrier, to enter the mitochondria, and even has the ability to translocate to the nucleus under certain conditions. Once in these i
