Randomized Controlled TrialBed rest does not induce hypercoagulability.
Although there is no direct evidence, it is generally believed that bed rest shifts the haemostatic system towards hypercoagulability; thus, immobilized patients are commonly treated with anticoagulants. We therefore aimed to investigate whether long-term bed rest actually leads to an elevated risk for thromboembolic events. ⋯ Our data indicate that the re-ambulation period is associated with a tendency towards hypercoagulability: ttPeak and StartTail were significantly shorter, Peak and VELINDEX were significantly higher compared to baseline. Moreover, plasma levels of F1 + 2, TAT, FVII and FVIII were significantly higher compared to baseline. The results from our study suggest that bed rest by itself is not associated with hypercoagulable states in healthy subjects.
