The Predictive Value of the 4Ts and HEP Score at Recommended Cutoffs in Patients With Mechanical Circulatory Support Devices
The 4Ts and HEP scores have a modest predictive performance for probable HIT in patients requiring MCS devices. A low 4Ts or HEP score does not reliably rule out HIT in patients requiring MCS, and clinical suspicion for HIT should be investigated, utilizing laboratory tests in this population.
