Changes of coagulation parameters during high altitude expedition

2010

Data on changes of haemostatic parameters at altitudes above 5000 m are very limited. So far it is unknown, whether altered coagulation could contribute to the development of acute mountain sickness.Thirty four healthy mountaineers were randomised to two acclimatisation protocols and undertook an expedition on Muztagh Ata (7549 m) in China. Tests were performed at five altitudes up to 6865 m. Haemostatic parameters, such as PT, aPTT, D-Dimer, APC-Resistance (APCR), von Willebrand Factor activity (RCo), ADAMTS-13C-Natriuretic Peptide (CNP) were assessed together with Lake Louise AMS score.D-Dimer significantly increased with increasing altitude (median 0.62 to 0.81 mcg/L, p0.0001).
