May indicate transient hypercoagulability persisting after presyncope; hypothesis-generating for thromboembolic risk in vulnerable patients.
Does presyncope induced by head up tilt and lower body negative pressure alter coagulation markers in healthy males?
Presyncope induces hypercoagulability that persists into recovery, which may represent a thromboembolic risk factor in vulnerable patients.
Cvirn et al. (2012) studied this question.
