Pulmonary haemodynamics by echocardiography over 3 days of acclimatization in lowlanders with chronic obstructive pulmonary disease travelling to 3100 m of high altitude
In stable patients with chronic obstructive pulmonary disease travelling to and staying at 3100 m for 3 days/nights without adverse events, sPAP initially increased, along with an increased pulmonary resistance and a reduced right ventricular-arterial coupling reflected by a lower TAPSE/sPAP. Whereas sPAP steadily decreased during acclimatization, other echocardiographic parameters remained unchanged.
