Advancing high-altitude medicine: a model for the future

With rising global high-altitude travel, occupational exposure, and permanent habitation, the health burden of high-altitude-specific diseases and high-altitude-related diseases has become increasingly prominent, highlighting an urgent need for in-depth research and clinical solutions in high-altitude medicine. To bridge this gap, this prospective review first proposes the Hypoxia Stress-induced Multi-organ Injury (HSMI) Spectrum as a novel, unifying research paradigm-one that seeks to overcome the limitations of fragmented traditional research by integrating insights into hypoxia-driven multi-organ pathophysiology. Despite growing foundational advances, critical barriers remain: incomplete understanding of individual hypoxia susceptibility mechanisms, overreliance on subjective and non-mechanism-based diagnostic tools, and a profound translational chasm between basic research and clinical therapeutics, especially for vulnerable groups like neonates, the elderly, and females. Building on the HSMI framework, we outline a comprehensive advancement strategy that includes establishing an integrated systems-based research model leveraging multi-omics and machine learning, deciphering core hypoxia-driven molecular pathways, developing objective real-time diagnostic systems with biomarkers and portable imaging, and innovating mechanism-based precision therapeutics. Implementing this HSMI-centered model will strengthen the scientific foundation of high-altitude medicine, optimize the prevention, diagnosis, and treatment of high-altitude illnesses, and offer a scalable framework for addressing health challenges in extreme hypoxic environments worldwide.
