Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This study evaluates two different methods for monitoring a patient's anti-clotting \[heparin\] therapy after they receive a heart pump implant \[left ventricular assist device -LVAD\]. One method tests for how long it takes the patient's blood to clot and uses that to determine if they are on the right dose of heparin. The other method uses a more direct measure of how much heparin is in the blood. The hypothesis is that the method that more directly measures how much heparin is in the patient's blood will provide better medical results for the patient's care after they have the heart pump implant. To that end, the investigators are conducting this feasibility trial to establish the logistics associated with the implementation of these heparin monitoring approaches.
