Right heart function and pulmonary pressure in asthma patients during 17 days at high-altitude

Conclusions: In otherwise healthy asthmatics exposure to high altitude induces a significant increase in mPAP and heart rate with a decrease in SI resulting in an unchanged CI. During the 17 days at 3200m there is no further change in the indices of RVF despite increasing SpO2. Thus, respiratory acclimatization is more rapid than the one of the pulmonary circulation.
