Clinical TrialHighlightedThe Effects of Hydrogen Gas Inhalation on Adverse Left Ventricular Remodeling After Percutaneous Coronary Intervention for ST-Elevated Myocardial InfarctionMHID-7076048PMID: 283210092017Circulation JournalYoshinori Katsumata, Koichiro Homma, Masaru Suzuki, Shigeo OkudaBackground: Hydrogen gas inhalation (HI) reduced infarct size and mitigated adverse left ventricular (LV) remodeling in a rat model of acute myocardial infarction (AMI). We designed a prospective, open-label, rater-blinded clinical pilot study in patients experiencing ST-elevated MI (STEMI). Methods and results: The 20 patients with an initial diagnosis of STEMI were assigned to either an HI grou
