简要总结
This study is a multicenter, prospective, randomized, open-label, parallel-controlled clinical trial. The participants are adult patients with high-altitude polycythemia who have been long-term residents (for >6 months) in regions at an altitude of ≥2500 meters. Participants are randomly assigned to one of two groups: a conventional medication group and a remote ischemic conditioning (RIC) intervention group. The study aims to evaluate the effectiveness of a standardized 90-day RIC intervention, as an add-on to conventional medication, in managing high-altitude polycythemia.
