Supplemental oxygen therapy & relocation to low altitude in highlanders at risk for PH, & patients diagnosed with PAH at high altitude

Presented at PVRI 2026 Congress by Silvia Ulrich, University of Zurich

Summary

High altitude living affects health, particularly in Kyrgyzstan's highlanders. Healthy individuals show reversible pulmonary pressure changes with oxygen treatment, unlike those with pulmonary arterial hypertension (PAH). Defining PH at high altitudes poses challenges, and access to treatments for PAH patients is crucial. The impact of environmental factors and the importance of sleep studies are highlighted, along with a call for collaboration in future research.
